Aquaponics on Mars with Benz Kotzen (GotG61) – The Unconventional Gardener

[Orbital Gardens, this is Mission Control. We are confirming acquisition of your signal. You are live in 5, 4, 3, 2, ….

Hello, and welcome to Gardeners of the Galaxy, the podcast for all of the sentient beings in the Universe who have a passion for plants. I’m Emma the Space Gardener, and I will be your host as we explore gardening on Earth… and beyond!]

…

It has been an thrilling summer season in area, with two astronauts from the Polaris Daybreak mission conducting the primary non-public spacewalk. That mission additionally included an astrobotany experiment – LEO PLANTS – from the US Air Drive Academy. That workforce is now partnering with Rhodium Scientific to ship Arabidopsis vegetation to the Worldwide House Station with Crew 9, to develop in low Earth orbit there for 4 to 6 days. The Polaris Daybreak mission flew at the next Earth orbit, so a comparability between the 2 units of outcomes might present insights into the manufacturing of crops on long-duration area missions or in higher-radiation environments.

Our Mission Specialist for this episode is Benz Kotzen, a Professor of Panorama Structure and Nature Primarily based Options on the College of Greenwich. Benz’s analysis focuses on actual world points and fixing them by combining new and previous applied sciences with revolutionary and tried and examined pure options.  He has particular experience in arid lands, restoration and aquaponics. He additionally initiated and manages the inexperienced roofs on the Stockwell Avenue constructing in Greenwich. He’s right here to inform us about his FEEDING MARS venture, which showcased a stay experiment rising greens, herbs and fruits in Martian simulant soils, utilizing fish effluents from an aquaponic system as fertilizer.

Interview transcript

Emma (00:02:20):

Hello, Benz. Thanks for approaching the present right now. It’s nice to have you ever right here. And we’re going to be listening to about some actually fascinating analysis that you’re doing. So howdy.

Benz (00:02:37):

Hello, Emma. Thanks very a lot for having me on the present. Actually recognize it.

Emma (00:02:41):

You might be most welcome. OK, so you’re a professor of panorama structure and nature-based options on the College of Greenwich. And one of many areas that you simply’re significantly focused on is aquaponics. So are you able to clarify to us what aquaponics is, please?

Benz (00:02:58):

OK, so, aquaponics is a meals manufacturing technique which truly has been round for hundreds of years, and it was practiced and it’s nonetheless practiced just about in China right now after which additionally on the time proper the world over, I imply South America by the Aztecs and in a method it’s nonetheless practiced right now in Mexico Metropolis.

Benz (00:03:21):

So what it’s principally is what you do is you feed the fish and by feeding the fish, the fish produce clearly waste merchandise, and these waste merchandise turn out to be the vitamins for the vegetation. And, you already know, this has additionally been going round for hundreds of years. In fact, folks have been utilizing horse manure and issues for rising vegetation. So it’s in an identical method, besides what the system depends on is, after all, is fish are produced or rising in water and what we’re doing is by feeding the fish, the vitamins which come from the ammonia which is being produced from the gills of the fish in addition to from their urine, after which additionally the waste that’s coming from the faeces, however we are able to discuss that as a result of we take away most of that.

Benz (00:04:08):

That nutrient is transformed completely naturally within the water by microbes that may happen truly completely naturally after about six weeks in any water. And these microbes change the ammonia, which is what we’re speaking about now, from ammonia into nitrite,  after which from nitrite into nitrate. And nitrate is fertilizer for vegetation, principally. After which, after all, we’re speaking about potassium and phosphorus, that are the principle type of vitamins.

Benz (00:04:40):

Now, what we’re doing truly, so now we have the fish in tanks and this water is then being filtered by. And now we have very, very, at our college, now we have very non-sophisticated filtration strategies. I can clarify. So the water is passing from the fish tanks into these filtration strategies, eliminating many of the faeces or eliminating the faeces. After which it’s flowing into plant tanks. And the roots of the vegetation are dangling within the water. The vegetation are floating on some rafts and the vegetation are absorbing these vitamins as they go previous, cleansing the water. So that is the opposite a part of it, cleansing the water that then will get pumped again to the fish.

Benz (00:05:22):

Now, it’s very, very vitality environment friendly as a result of all the method that goes from the fish by the filtration to the vegetation after which by quite a few plant tanks, it will get to a small pump on the finish of the plant tanks and will get pumped again to the fish. So it’s very, very environment friendly. And also you’re getting multiple product for what you’re placing in. So yeah, so it’s fairly sustainable.

Emma (00:05:47):

Okay. So if we take that on board, what made you get focused on whether or not aquaponics would work on Mars?

Benz (00:05:57):

Okay. So after all there’s been lots of speak and lots of stuff within the media about man[kind] transferring away from planet Earth to the Moon in addition to to Mars, that are the one type of two different type of locations in our photo voltaic system the place man[kind] might presumably survive, clearly with very particular type of tools and stuff like that.

Benz (00:06:22):

Nevertheless it’s a little bit little bit of a protracted story as nicely, as a result of principally the Moon and Mars are very,

very hostile, despite the fact that man can stay there underneath, you already know, closed situations in area, I assume in pods and issues like that. However now we have locations on Earth that I’ve visited

that are very, similar to the locations on Mars, okay. And these locations, for instance, are very arid and so they don’t have what we’d name soils so the factor about Mars and the Earth, they’ve issues that are known as regoliths. And regoliths are principally rocks which were worn down over time by radiation, by chilly and warmth, et cetera, et cetera.

After which principally that type of makes finer particles and it’s on the way in which to creating soil.

Benz (00:07:15):

However so as to have soil, so as to have one thing to develop in these regoliths, you truly must have natural materials. And clearly on Mars and the moon, we don’t have natural materials. And in some locations on Earth, like, for instance, in Africa, very dry components of Africa, I’ve travelled there and it made me suppose, you already know, these individuals who stay there wrestle enormously to make a dwelling, additionally to get recent produce. You realize, they’d stay on, I assume, animal meat, goats and stuff like that and milk primarily. However they don’t get any greens, can’t develop something, and so forth.,

Benz (00:07:57):

And I began taking a look at aquaponics for these type of areas. After which studying concerning the Moon and Mars, these two type of areas type of paralleled each other. And in order that was it. And it additionally made me suppose, you already know, why is this type of rush to get to the Moon and Mars? And, you already know, I began trying into it. And it type of grew to become apparent ultimately that sooner or later we’re going to have one other extinction occasion on Earth. It’s inevitable. And mankind goes to vanish, presumably disappear on Earth.

Benz (00:08:31):

And the concept is, you already know, clearly there’s a scientific purpose why folks need to go and the political the reason why folks need to go, geopolitical the reason why folks need to go to Mars. However the principle purpose is to create one other a part of human civilization someplace if we get destroyed on Earth. And that type of me.

Benz (00:08:49):

And I believed, nicely, OK, you already know, if you happen to go to the Moon, you could possibly most likely get a McDonald’s to the moon in a few days. However on Mars, you possibly can’t do it as a result of it’s eight months away or a yr away. And so it’s a must to develop your individual meals there.

Emma (00:09:06):

Yeah. Though it did make me suppose, I believe anyone stored a McDonald’s burger underneath a bell jar for years and years and years and it didn’t change very a lot. So it’d truly survive the journey to Mars!

Benz (00:09:21):

Sure, you most likely don’t want a lot type of remedy. I assume you could possibly vacuum pack it as nicely, simply to verify.

Emma (00:09:30):

Okay, so that you and your colleagues, you carried out a pilot research in Greenwich known as Feeding Mars, and that was in spring 2022. So what did that contain?

Benz (00:09:41):

Okay, so on the time, I believe I had a possibility. Sure, this was mulling round in my head. And there was, I used to be attempting to consider tips on how to do a venture. And I believe some type of inner funds and monies took place. And I believed, nicely, okay, what I’ll do, I received’t do a type of all singing and dancing, you already know, bells on the wrists and ft venture,

which might take lots of money and time.

Benz (00:10:07):

I can do a really small venture, which can simply take a look at the rules and see whether or not the type of proof of idea would work. And I managed to do that with a, you already know, a really,

very small funds in a, in a just about small time frame.

Benz (00:10:22):

And on the identical time I had this concept of, you already know, I used to be attempting to determine the place I used to be going to place this in on our campus. And I believed, nicely, you already know, that is one thing that I do know folks will likely be focused on. Why don’t we put it in a type of exhibition or gallery area? You realize, one thing that myself and different type of scientists or researchers wish to do is to convey analysis to the general public. Yeah. And that was, you already know, all of it type of fitted collectively fairly nicely on the time. In order that was type of the impetus for doing it then.

Emma (00:10:58):

And what did the venture truly contain?

Benz (00:11:01):

OK, so the venture itself concerned is principally the precept of aquaponics, which, as I stated, what you want is fish tanks, and also you want some filtration. You additionally want to have the ability to clearly have the vegetation as nicely. Now, there are totally different sorts of aquaponics programs there. There are aquaponics programs like now we have on our roof, which I described, which is a type of a return system. It’s known as a recirculating aquaculture system, RAS. And the water, as I stated, goes from the fish by the filtration to the vegetation, will get cleansed, goes again to the fish. Right here, we’re not doing that.

Benz (00:11:38):

What we’re doing is we’re taking the water from the fish, we’re filtering it. And what we did is take that water and put it on the vegetation. And that is principally what we name a type of soil-based aquaponics, which truly is an anomaly as a result of aquaponics usually doesn’t have any soil concerned. However, you already know, we might have pure aquaponics programs on the Moon and Mars, type of this one-way type of system which retains type of perpetually going spherical and spherical, or we may be extracting the vitamins from the aquaponics system after which placing it into the regolith. And so placing the microbes, 

et cetera, into this regolith or to the soil after which so making it truly alive.

Benz (00:12:22):

And truly that’s one of many rules of natural agriculture, et cetera, that the soil must be alive. The soil of locations in Africa, which I spoke of, and on the Moon and Mars, in Africa there would nonetheless be some microbes, et cetera, in these very harsh regoliths, however on the Moon and Mars, there’ll be no microbes. However what we’d be doing is placing these microbes into this regolith and attempting to create a soil, so a dwelling soil.

Benz (00:12:48):

So what we did, attempting to emulate the type of factor that might occur on the Moon and Mars, we additionally bought a develop tent, which is principally utilized in very intense agriculture of a sure variety. And so principally, they’re actually fairly good issues in themselves. It’s about two and a half metres tall, the one we had in about one and a half or two metres sq.. And inside it, it’s acquired very extremely polished silvery surfaces on the within. There’s home windows that you may look into, which is nice, so the folks might look into it. After which there’s a really robust gentle, after all. So what we’re doing is we’re attempting to emulate daylight and, in actual fact, much more intense gentle in order that we are able to get the vegetation to develop.

Benz (00:13:33):

After which principally that’s what we did. We put this all collectively. After which we planted the produce or the vegetation in a wide range of regoliths and soils. So what we did with regard to the planting medium, there’s a firm in the US known as the Martian Backyard who produce simulant Martian soils for analysis functions. And we acquired in contact with them, and so they put collectively a mixture of regoliths, what they thought can be good for us. However, you already know, importing it from the US was costly.

Emma (00:14:09):

It’s vastly costly, the delivery, yeah.

Benz (00:14:12):

Sure. We couldn’t develop every part in that simulant. So what we had was what is named an analogue, which principally what we did is I adopted, I assume, a recipe for making a Martian soil utilizing the components that had been devised by the Chicago Botanic Gardens. So I truly manufactured these regulars right here within the UK.

Benz (00:14:38):

Now, the components are just about the identical, however I believe the simulant that got here from the US was a little bit bit extra subtle. Principally, the rocks on Mars are basalt, and so they’re pink basalt, whereas, for instance, within the UK, it’s gray basalt, nevertheless it’s the identical stuff. After which this feldspar and some different issues. So we had two, I assume, Martian regoliths that I used to be utilizing.

Benz (00:15:05):

So, for instance, utilizing the pink regolith, which got here from the US, we grew issues in smaller pots like lettuce and onions and issues like that. However after I was rising potatoes and beans and issues like that, I used the gray regolith, which I manufactured myself or made myself due to the price.

Benz (00:15:25):

After which, after all, we needed to have a management medium to see how the vegetation would carry out compared to, for instance, a horticultural soil, only a regular horticultural soil that you simply get from a DIY store, after which these two totally different sorts of simulants.

Emma (00:15:42):

That sounds actually thrilling. Actually fascinating.

Benz (00:15:46):

Yeah, it was. It was enjoyable. Quite a lot of enjoyable. Yeah. Yeah, I like doing issues which might be enjoyable and fascinating.

Emma (00:15:51):

Okay, so… What occurred? You place all this collectively. You had your exhibition. What occurred subsequent?

Benz (00:15:57):

OK, so one of many issues was the outcomes of what we did. There have been, I assume, simply taking a look at it in several methods. The exhibition concept was an excellent one as a result of folks had been crazily or, you already know, very, very focused on every part. They had been within the know-how. They had been focused on, you already know, why going to Mars, all the explanations behind it. They had been focused on how the vegetation had been rising from everyday, and so forth.

Benz (00:16:27):

So, you already know, we had folks from exterior, after all, after which it was in a in an extension of a gallery area the place college students might stroll by day-after-day. And there can be myself and one other PhD scholar who can be taking care of the vegetation, and so forth.

And day-after-day we’d have questions and interplay with primarily college students and workers,

however then after all on the weekends and in addition through the week from individuals who got here into the gallery area. Our floor ground of our constructing in Greenwich is definitely open entry, so members of the general public can are available, and so they did.

Benz (00:17:03):

After which by way of the outcomes, one of many issues we additionally did was we additionally had a little bit develop tent the place we grew all of the seedlings and issues like that. We grew them within the in these totally different regoliths and within the horticultural soil. After which we transferred them into the larger pots as soon as they had been viable as seedlings. The outcomes on the entire had been very constructive.

Benz (00:17:28):

On the entire, the vegetation that had been grown within the two regoliths didn’t carry out in addition to the horticultural soil, which is just about to be anticipated in a method as a result of there was a type of error in type of what we did.

Benz (00:17:44):

In hindsight, it appeared… one thing we must always have completed. And in addition with the horticultural soil, there was a type of a little bit little bit of an error. So what occurred is many of the vegetation, for instance, the potatoes, we produced potatoes in each the regoliths and, after all, within the horticultural soil, however a couple of extra potatoes, for instance, within the horticultural soil.

Benz (00:18:08):

The beans, we acquired beans. Each plant did okay. The onions had been fairly comparable. We had lettuces, and what was fascinating, truly, with the lettuces and the potatoes, these species truly was far greener in color. So they’d far more nitrogen in them. And that is coming from the fish water than that was coming from the horticultural soil.

In order that was very fascinating.

Benz (00:18:36):

In hindsight, the factor that we must always have completed, which was fairly foolish of me, was after we began the seedlings, I began the seedlings by rising them with simply regular water. After which, truly, no, I didn’t. I began them utilizing nonetheless regular water for the horticultural soil. After which for the regoliths it was the fish water.

Benz (00:18:57):

So that they, they, they, each of them grew advantageous, uh, at seedlings and, and that’s fairly regular as a result of most seeds and seedlings that, you already know, the seeds even have the vitality within the seed to provide the seedling. So as soon as the seedling is grown, we transferred it to the pots. However what I ought to have completed is I ought to have began watering these pots or placing fish water into these pots so the microbes began already working. So as a substitute of ready a little bit bit, you already know, so principally we had a type of slowed response within the regulars with the fish water, whereas the horticultural soil was already type of, you already know,

swimming with vitamins after which the vegetation might simply develop.

Benz (00:19:39):

The opposite factor, after all, which type of skewed issues a little bit bit was truly, so while after we had been feeding the regoliths with fish water and you could possibly see, for instance, that the potatoes had been inexperienced and the lettuce had been inexperienced, every part was greener with the regolith pots, there was a beginning to get a nutrient deficiency, the horticultural soil, as a result of most horticultural soils truly, you already know, they are saying they are going to have sufficient vitamins for a month or no matter it’s.

Benz (00:20:08):

And so…However, you already know, all in all, it was by no means meant to be type of this huge, heavy hitting scientific train. It was a proof of idea to type of present that, you already know, this type of analysis may be completed and that we wish to, you already know, take this ahead into a much bigger venture. However we did type of show that, you already know, we are able to develop vegetation, sure sorts of vegetation. In fact, we didn’t develop every part. We selected a type of balanced weight-reduction plan for our neighborhood on Mars. However we didn’t develop completely every part, after all, as a result of it’s simply, you already know, simply not sufficient area and money and time.

Benz (00:20:46):

Yeah, however we’ve proven that, you already know, even with our type of little primitive experiment,  folks might have survived. We had potatoes, we had beans, we had lettuce. You might get your greens, and you could possibly get a little bit little bit of flavour from the onions and stuff like that.

Emma (00:21:04):

Mark Watney would have had a a lot simpler time on Mars in the event that they’d despatched him with a couple of packets of seeds, wouldn’t he?

Benz (00:21:09):

Precisely, precisely, sure.

Emma (00:21:11):

Not simply regular weight-reduction plan potatoes.

Benz (00:21:13):

Sure, and some fish. I imply, the opposite factor about having fish on Mars, sure. So by taking fish, let’s say, to the Moon and Mars is, you already know, we’re speaking about making a dwelling soil. Now, after all, if you’re rising any type of vegetable, whether or not it’s in if you happen to’re doing it in soil or in a pot and even in aquaponics, you’re going to get some detritus. You’re going to get some leaves that not doing so nicely. You’ll lower them off.

Benz (00:21:44):

You’re additionally going to, for instance, a few of, you already know, some, you already know, if you happen to’re making a lettuce salad, there’s some components of the lettuce you’re not going to make use of. So that you may be making compost from that after which including it to the soil. After which the opposite factor is that, for instance, you’re going to have fish. When you’re going to eat the fish, then you definately’re going to have the bones and the pores and skin and et cetera, which can also be going to then turn out to be extra vitamins that you may put again into the soil. So you’ll type of have this type of enrichment happening this course of happening and you already know now we have right now now we have this um this idea of the round financial system uh you already know the place waste is a part of the entire manufacturing system and that’s precisely what you already know would occur in one thing like you already know having fish on or aquaponics on Mars

Emma (00:22:33):

Yeah. OK. And so that you talked about that this was a pilot venture, and also you had hopes of it changing into one thing else. Are you happening and doing extra analysis on this space? Is that also on the playing cards?

Benz (00:22:44):

Sure, it’s on the playing cards. It’s simply, you already know, you already know, discovering funds for analysis initiatives.

Fairly often notice, I imply, generally there are open calls.  So, you already know, you possibly can simply ship in a analysis venture, et cetera. And it’s very time consuming. And the probabilities of getting them are type of slim. However generally there are calls which might be very directed. After which, you already know, most likely simply ready for a directed name or a little bit little bit of more room and time, which I can, you already know, I can work on.

Emma (00:23:17):

OK, so we’ll sit up for that and we’ll maintain our eyes out that that will likely be arising sooner or later. OK, so I don’t know whether or not you simply noticed the information that Blue Origin simply took a biologist into area. He was doing his personal analysis on their suborbital flights. Rob Ferl was performing some experiments with vegetation in little tubes.

Emma (00:23:39):

I all the time ask folks, you already know, in the event that they got that chance to take their analysis into area, would they need to go? So would you need to go into area? Would you need to go to Mars?

Benz (00:23:47):

Sure, for positive. Yeah. Yeah. Sure, I’d. I imply, sure. Sure, I’d. I believe I believe I imply,

one of many issues, you already know, I used to be attempting to get my head round after I was enthusiastic about having colonies on Mars was why would anyone need to go to Mars? As a result of truly we stay on paradise. I imply, I’m simply looking my window and I can see, you already know, it’s simply phenomenal.

Benz (00:24:12):

You realize, there’s organic life and that doesn’t exist so far as we all know anyplace else

amongst the billions and billions of galaxies and stars and black holes and all of it so far as we all know. And so we stay in a spot which has acquired a lot biodiversity and stuff like that. And there’s a lot variety that I nonetheless have to see on this planet.

Benz (00:24:34):

So, you already know, I imply, you already know, I imply, though all of us have been, I assume, fortunate to have travelled or most of us, however we’ve seen, you already know, most of us simply don’t see the entire planet. So I assume if I might go to Mars and are available again, I don’t need to keep there.  Then that might be good. I would really like that, however I’ve nonetheless acquired a lot to see and, and, and take a look at in, um, on Earth.

Benz (00:24:57):

I’d, I imply, the opposite day, for instance, I used to be travelling, and I noticed a chameleon cross the street. And, you already know, I imply, what number of tens of millions of years does it take to make a  chameleon? You realize, and I imply, simply taking a look at any type of plant, you already know, any plant that’s drought tolerant or it’s acquired leathery leaves and, you already know, and might survive with out water an entire, you already know, an entire yr and issues like that. How lengthy does nature take to try this?

Benz (00:25:26):

And there are literally thousands of these totally different species and such who all have tailored or do various things. After which, after all, we’re not speaking concerning the, you already know, then there’s the bugs and the animals and such.

Emma (00:25:38):

And the ants.

Benz (00:25:38):

And, you already know, who is aware of about, no person is aware of about all of the ants. So, sure, I’d prefer to go there, come again and discover the remainder of the Earth.

Emma (00:25:46):

Sounds good. OK, so that you’re packing on your journey to Mars. You’ve acquired all of your analysis vegetation and all of your meals, every part like that’s set. However there’s room in your baggage for one plant to be your private companion on the journey. What plant would you select to take with you and why?

Benz (00:26:04):

OK. You could possibly collect from my accent that I originate in South Africa. I originate most likely in the midst of the nation from Johannesburg. All people’s heard of that. However after I was a toddler, and even right now, if I journey from the center of the nation to the north,

we begin getting baobab timber. And baobab timber, in actual fact, if you happen to go to the Kruger Nationwide Park, which is the sport reserve within the northeast of South Africa, there’s the southernmost baobab tree on this planet.

Benz (00:26:42):

After which I’ve travelled in Kenya as nicely. And also you get these forests of those baobab timber. And these baobab timber are, there’s one thing about them. You realize, they’re principally what’s above the tree is fairly much like what’s beneath the tree. So it’s type of roots within the sky. And there’s one thing very phenomenal. And a few of these timber are so huge that they’ve been hollowed out and folks stay in them. And, you already know, and so they’ve acquired tales to inform and so they’ve acquired this biology and this historical past that’s so phenomenal. Now, you already know, in area, Baobab tree, I assume, would by no means be allowed to get full development.

Emma (00:27:24):

Not but.

Benz (00:27:24):

No, no. You’re going to must have a fairly type of costly pod or area you already know, glasshouse to maintain your baobab tree. However yeah, it’s only a phenomenal species. And those, you already know, they’re all barely totally different. Those in Madagascar, for instance, are simply so lovely. There’s one thing concerning the trunk, which is type of elephantine and,

you already know, like elephant pores and skin and stuff. It’s simply lovely. They’re lovely issues.

Benz (00:27:53):

After which, after all, additionally they produce a fruit known as, or a pod, a seed pod, which is principally cream of tartar. That’s the place we get cream of tartar from. And it principally means cream of tartar, you can also make truffles.

Emma (00:28:08):

I didn’t know that.

Benz (00:28:10):

Sure, it’s. That’s our origination. I believe now they most likely make a chemical model of cream of tartar. However yeah, that’s it’s an elevating agent. And that’s the place it initially comes from.

Emma (00:28:21):

Yeah, that’s wonderful. I don’t know whether or not anyone’s ever tried to bonsai a tree so you possibly can have an area model.

Benz (00:28:31):

There are different succulent kinds of vegetation which type of appear to be baobab timber. However I believe after they’re small, they don’t look something like after they’re huge.

Emma (00:28:41):

I used to be simply attempting to think about what a baobab seedling would appear to be, and I’ve acquired no clue,

so I’m going to must go and Google that now. They arrive in these huge pods, longish, I assume possibly a foot lengthy pod, which is type of, I believe, a little bit bit furry, khaki inexperienced or

brown after which inside there’s this vary these black seeds – I believe they’re black seeds – inside this white powder which is the creme of tartar.

Emma (00:29:14):

Yeah wonderful, yeah no that’s completely wonderful

Benz (00:29:16)

I don’t know why they don’t name it creme of baobab!

Emma (00:29:22):

No, I imply, I’m assuming it’s fairly a sluggish rising tree as a result of they’re very lengthy lived aren’t they?

Benz (00:29:29):

Sure sure sure so good although. Yeah, hundreds of years previous, a few of the, sure, positively, yeah. I assume all timber type of develop horizontally in addition to vertically, however the baobab places lots of effort in rising horizontally, you already know, so the trunks are fairly, you already know, a few of them are huge. I assume that’s one of many issues why they develop slowly is as a result of they’re attempting to develop horizontally and vertically on the identical time.

Emma (00:29:53):

No, that’s wonderful. I’m simply picturing a baobab tree in my area greenhouse, so that might be completely sensible. I believe that’s great. Yeah. Okay. Yeah. In order that’s completely fabulous.
