Bump This is two weeks of growth. Lettuces, mint, eggplants from seeds out of eggplants I cooked, peppers under it all which I’m about to free.

 Any idea what this could be? Growing mangold in GHE flora series, I mixed it 1.5ml grow, 1ml micro and 0.5ml flower per liter. Could this be nutrient burn because of too much nutrients? Never grown anything but peppers in hydro before. Edit: I guess it's called Chard in English. Sistergodiva fucked around with this message at 12:11 on Jan 8, 2022 |

That looks like it could be leaf spot, a fungal infection. That one won’t go away so I’d pull it before it spreads.

Usually nutrient burn is a universal thing that shows along the tips of the leaves all around. I’d chop off that leaf and see what happens, all the other ones look happy

Yeah already removed some leaves. Seems to keep happening to more leaves. I think I hosed up by starting them in the tub with high water level, so the rockwool got mouldy.

Sistergodiva posted:Yeah already removed some leaves. Seems to keep happening to more leaves. Yep. Once it’s in the plant it doesn’t go away. Sanitize all your surfaces with a surface sanitizer. Bleach works when there aren’t plants around, I’ve used my food safe brewing sanitizers before but they’re more expensive. The surface wipes can also work, but give everything a good scrub and sanitize to keep it from coming back.

Any chance that other plants in the same tub could be ok? Or should I just cut my losses and remove everything and sanitize and replant? I have some StarSan I assume you mean something like that?

I liked that there's no worry about wiping it off and already have it laying around. If the others look okay, they might be. It's the curled leaves and yellow/grey spots. I started putting grapefruit powder and paying more attention to the oxygen levels in the water when it happened to me. Better circulation on the leaves would also help keep it away.

It’s tougher when it’s tight on space of course. That’s a cool looking cabinet space for it. It’d be easier if you put it in the middle, they can get to be large plants. Mine get 16-18” tall outside, but I don’t do greens indoors anymore. Ran out of space for it and I still have four plants growing outside with the cabbage and collards. Benefits of moving to a climate with less cold in the winter. Now I mostly just use the indoor setup for rooting peppers and other house plant cuttings.

A cautionary tale. I've never grown broccoli before and I always like trying out new things in the grow tent, but I was not aware at how monstrous broccoli is. I assumed, what, like 2-3 feet tall to make a broccoli? More like 5ft! Does broccoli normally grow this large?  It is just about done, but it shaded out everything growing in there with it, including some parris island romaine that decided it would just grow up to where it could get light. Anyone ever see a romaine vine?  The photos don't do it justice just how dense and jungley it is in there, but someone gonna have the most expensive broccoli side real soon now! The lights consume about 30 cents worth of electricity and the plants consume over a gallon of nutrient solution a day. These bois have been growing since early November.

I tied to grow cabbage in my aquaponics setup when I had it and I had a similar thing happen- the leaves just got huge and it never formed a head. I suspect brassicas just don't do what they are supposed to when not in soil.

Oh it is growing broccolis too, you just can't really see them at all through all the leaves. You can kinda see one poking up on the last photo. It just cracks me up how giant the thing is when every photo I have seen shows broccs being harvested from 2ft tall plants.

I suspect brassicas just don't do what they are supposed to when not in soil. I was able to grow red cabbage in my NFT setup. Decently dense heads, only real problems were they choked out the tube at times causing it to overflow and my eternal curse: aphids. Last year I grew exclusively tomato, pepper, and eggplant because those fuckers loved the broccolini and other leafy stuff (it's all outdoors). I'm not sure if it's soil they need vs some sort of stability for the roots to hold onto - I'm going to try brussel sprouts again this year in my clay/pearlite buckets.

So glad I found this thread. I was hoping to get a more balanced view of how hydroponic lettuce *really* goes, and finding people talking about everything constantly dying of molds and aphids does great for putting me off throwing down $100 on all the hardware and consumables for 6 wilty gross lettuces and then giving up.

I'll say this as someone who has now had multiple aquaponics and hydroponics setups- you need to look at it as a hobby, not a way of actually efficiently growing food. It's almost like figuring out a puzzle and any food you get is a reward. To do it efficiently it has to be done large scale with natural sunlight. The biggest trap in hydroponics is that youtube has hundreds videos showing systems in their prime a month or so in, but almost nobody has followup videos a year later showing all of the problems that ultimately crop up and cause most people to tear it all down. The few people that do have long term followups with working systems are all growing outside or in a greenhouse.

I started at "what the gently caress why would anyone buy this $900 automatic lettuce growing thing that can grow 12 lettuces at a time, once you factor in the running costs that'd take like 40 years with no problems to even pay for itself", then I found the $50 half-assed DIY ones and was starting to get tempted, but once I ran some numbers on the nutrients and pH balancers and poo poo it was looking like you're paying half the regular grocery store price of a lettuce per lettuce, plus a bunch of effort and the up front cost, and I assume the success rate is a fair bit less than 100%. (And I'm in Florida, where the humidity can grow mold and mildew even on an acidic piece of fire that's in a freezer.) I guess mustard/alfalfa/sunflower sprouting in a jar is more my speed.

I mean I love my system but I'm also a chemical engineer that never got to work in a refinery and loves Zachtronics games so an endless tinker system hits a lot of spots for me. That said, I've never had mold issues and just stopped planting things that aphids love. And as you point out, leafy greens are definitely on the "easier to just buy" end of the spectrum, but one or two plants gives me enough bell peppers in the freezer for over half a year and fancy tomato production, even after loss to birds and a very fat mouse, was ridiculous. Also, and this is the big selling point for me, it lets me do garden stuff without having to bend over.

Indeed. A home hydroponic vegetable garden is like if you made a machine that could turn charcoal into a single 1 carat diamond and all it takes is about 20-30 hours of your dedicated time over 4 months and $50,000 worth of supplies. I think we all started out thinking that maybe we were going to grow reasonably priced, perfect food but it is comforting to hear that others have had a bit of sticker shock when it comes to their hydroponic-grown delights. My broccoli grew for 3-4 months, using roughly $35 in electricity and about $10-15 worth of nutrients, or around $50 for 4 good sized heads of broccoli. The cauliflower that was in there too got so shaded by the broccoli it never achieved its potential, so I let it grow after removing the broccoli plants and it took off but then where the cauliflower would actually grow it just became filled with mold so I ended it. I am also in Florida and during the winter the indoor humidity is around 60% since both the A/C and heater don't really run, so it is challenging to keep up with a tent that's transpiring a gallon every day on top of that. This year I even bought a 50 pint dehumidifier ($220 + 60 cents a day) to run in the same room. It has a significant but ultimately fruitless effect on the humidity level. Yup, you gotta do it just because it is fun and interesting. Most of the other conditions such as watering, light intensity, fan speeds, and nutrient mix are fully under your control, so the whole thing is like a fun experiment more than anything else. I've also spent hundreds of hours building custom control solutions, sensors, designed PCBs, and had a dozen failures of trying some cheap eBay generic parts. I'm disappointed when things don't provide a product at the end, but it just means I'll either try again or just grow something else random next. And if anyone wants some of the billion thai bird chilis I still have in the freezer from a grow 2 years ago, swing by!

My insane plan to do aquaponics from a fish tank has failed and I lost everything. I still think it's 100% possible to set up a system that needs zero water changes ever. If I ever had the chance to try again I would buy green coconuts (live ones I mean), and try to germinate them from a salt water fish tank. Once that worked I would slowly add in more cool fish & corals and stuff. Alternately, there's glasswort or whatever it's called. That could be easier to manage.

I setup this 5x6'x2' "pond" outdoors and other than scooping about 30 gallons of water out during a freak thunderstorm all I ever did was top it off with the garden hose every couple of weeks. Rightnow I have water hyacynth and water lettuce sucking up all the nutrients, but if I removed about half, I could probably feed my family on the plant matter grown from this 150 gallon stock pond thing. Many thousands of goldfish live in stock ponds across rural america keeping the mosquito population in check Hadlock posted:Put together a 450 gallon above ground pond for father's day. It is about 6' x 5' x 2' deep Started out about two weeks ago with a bowl full of water, added some dirt from the pond site, leaves, moss, sticks from the immediate area in an attempt to cultivate something approaching local outdoor acquaculture to prime the pond. It's now a disgusting mosquito larvae infested dish. Soon to be fish food I guess. Color of the water looks like tea, orange brown but clear. Some pond plants arrived, tossed them in large Tupperware storage bin with a pump. My toddler promptly disassembled them but I think a few survived. Innoculated the Tupperware container with two ounces of water from the bowl of mosquitoes. With the aquatic plants and no fish the water has stayed very clear. I think I have ~4 lbs of ceramic and plastic bio balls in there And a year later: Hadlock posted:Pond update. Pretty amused how well this has worked over the last year or so. I'm pretty sure the huge amount of water relative to the number of fish has helped with the overall health of the system. Anyways Then I moved to California and things are going fine, I just top it off with a hose once a week (a lot hotter/less humid here) Hadlock posted:Ricefish breeding update plants getting out of ontrol Hadlock posted:I have a bunch of water pond plants you can have Hadlock posted:
Adding fish slowly, and not overpopulating the tank are key. I have like 3 dozen 1.5-2.0" fish + 3 Large goldfish plus six snails and maybe a couple hundred daphnia.

the actual purpose of the freshwater aquaponics setup was to try and flip the script: instead of maximizing fish and trying to use plants to recuperate waste into some kind of side product, the animals are instead only in there to convert whatever i throw in to fertilize the plants. I was thinking there's gotta be a way to figure out and model how nutrient loads work -- like electronics or something as a metaphor -- and if i can do this I can have completely crazy poo poo, avocados and limes and whatever stuff, basically for free by throwing dead leaves into a tank of water. The assumption being that throwing some stuff into water makes it break down pretty fuckin fast, possibly faster than in normal soil. Eventually you might be putting all kitchen and a lot of yard waste into a tank and it is able to rip through everything no problem, if you carefully select the tank residents. the saltwater version was supposed to be slightly different: stuff like coconuts or mangroves or whatever, but the system set up to self-regulate in a simple way, because a lot of saltwater animals have very fragile reproductive cycles and if you could have a reliable baseline system that stabilizes all that you could get crazy cool stuff like scallops and weird critters reproducing in there. It'd be like putting an electric grid in a state of continuous brownout, but for nutrients (which if they build up will kill the inhabitants), but also have the benefit of not needing all kinds of bullshit like nutrient skimmers and poo poo like that which is a huge pain to clean and deal with. The plants being strong enough and demanding enough that they strip every available bit of excess out of the water column. Somebody surely has already figured out this modeling system, but i couldn't find any info about it and tried to DIY

I just top off this planter every couple of weeks with untreated hose water. There's some heavy feeder pond plants on top, and a big ball of probably java or Christmas tree moss at the bottom, along with two small (1/2" and very fat - you can see a baby blue silver blur on the right of the first photo, that's one of them) fish and about 9 baby fish fry in there. And a chunk of cuttlefish bone about the size of my thumb. Total water volume is probably 8-12 gallons   My pond snail population exploded and I had a bunch of fry hatch about two weeks ago so I've been dosing it with a shake or two of fry food every morning during coffee. Also started picking pond snails out of there so they're not out-competing the fish for algae/infusoria. Also there might be a handful of daphnia in there keeping the water from going too green The yellow-orange stripe along the bottom is pH which is reading about 6.5-7.0 which is about right Hadlock fucked around with this message at 20:27 on Jul 24, 2023 |

This is an interesting idea I think you'd need a pool at least twice the size of a regular pool, so like 30,000 gallons to create a bioreactor for your kitchen/family of four. I'm not sure how exactly you'd model it but something like 4-8" of gravel on the bottom, some daphnia, pond snails and then I dunno like 40 medium to large size koi and 3000 rosy red minnows Probably like 2 cubic feet a week of biomass (leaves and sticks mostly) fall into my pool, presumably natural ponds of the same size have the capacity to absorb and digest this. The big problem I see, besides slowly ramping up the bioreactor/pond in your backyard, would be that if you go on vacation, or start eating out more regularly, you'll starve off a lot of your pond and end up with a death spiral fish kill with low-oxygen/hypoxic/blackwater situation. This could probably be solved by having an even larger pond (90,000 gallons?) dilution is the solution and all that
