In short, has anyone here looked into Wolfia Globosa as a food to grow in the limited space I have. Does anyone here have experience with it, or thoughts about it in general?To get started I'm planning to grow it in a wide metal washbasin I have, covering it with plexiglass roof and mosquito net sides to keep rainwater and insect away from it. It's a small tray though, so I'd need more space to grow any significant amounts of it. All hydroponics basins I've found are made of plastic, and I'm worried that with Globosa being an excellent bio accumulator it would also be excellent at absorbing microplastics into it. I'd need a total of 4 square meters of 20cm deep water, so where could I get large, wide, non-plastic basins for it?

Look for old bath tubs in the trash. As long as you don't mind cleaning it up, both the fiberglass and iron ones will last forever and neither should leach anything. Farmers use they as watering troughs for livestock.
>>2983938Thanks! I should clarify that the wash basin I currently have is about 2 x 0.75 meter one made for washing carpets, and what I'm looking for is something with several square meters of surface area. Something with the surface area akin a kiddie pool, but shallow and made of metal or some other non-leaching material.>>2983975Bath tubs are unnecessarily deep, as the water only needs to be about 20cm (about 8 inches) deep.
>>2983984>several square meters of surface area>8 inches deep>can't be plasticThe likelihood of finding something prefab meeting those specs I think are going to be pretty low. If I needed what you're describing, I would probably have a piece of sheet metal delivered, 16" larger in each dimension than the tray, and use some boards and a hammer to bend the sides up and fold the corners over, forming the tray. Or using a metal brake if you have access to one.Like this, only on a larger scale and without mangling it in the process:https://www.youtube.com/watch?v=rcDhx2IJdtE

>>2983984Doesn’t sound like a super good idea to me. I didn’t try your use case but did a lot of hydroponics and a good rule is you don’t put everything in a single huge tank. It makes things unwieldy and introduces unnecesary risk. Easier and better to compartment stuff. Just get 4 or 8 or 16 of whatever of that rug washing tin, or some 1200x800 pallet drip trays. Weld them together if you must, you could even stack them.
>>2984007This is what I thought too, so making them yself seems like the best way to go about it. Thanks for the seamless video, getting the corners watertight has been my biggest hurdle with this idea.>>2984195Thanks for these tips too. My logic was that a single large pool would be less work to fill than several small ones. A steel drip tray would be absolutely perfect for this, as long as I can find where to get them in Finland.
>>2983927Literally anything with water and sunlight, just urinate a little bit in the water and it will grow great.If you really want to be fancy you could have a tilipia farm where they eat bugs and duck weed so you have both du k weed and fish.https://m.youtube.com/watch?v=T15gXm6ha_I&pp=ygUMdGlsYXBpYSBmYXJt
>>2984027They are only weeds because people don't like seeing it, and mug property values come into effect, but it removes toxins and provides protein for fish and wild life.
>>2984195>don’t put everything in a single huge tank.this so many hydroponic start up get diseses because the soil acts as plant immune system and without it the plants have aids
>>2984569I've heard that diluted urine works, so I'm definitely going to use that outdoors. I've heard of fish being beneficial too, but I don't want to take responsibility for animals.
>>2984579They displace native wetland plants
>>2985339why you green homos care about that but are ok with invasive human species ?
>>2983927Oh I don't suppose you just saw that newish video about unlimited food ponds and that's why you're interested in Duckweed?https://www.youtube.com/watch?v=v3T8CAR3cTU
>>2985339They are native to most of the world, just different species.
>>2986335Yeah I was wrong but they can become a nuisance because they thrive in runoff and shit water and proliferate faster than most other plants
>>2986381Theyre a symptom mostly of too much phosphorous often caused by sewage runoff or fertiliser/detergent in the water
>>2983927>DuckweedThe first I've heard about that plant was when I saw a thread about people discussing the treatment section of a water loop system for the plumbing of some sort of "off grid" project.
>>2986640It is indeed excellent at sucking up all kinds of things from the water - which is why I'd rather not grow it in microplastic-seeping containers.
>>2987836If stainless isnt an option you could always go with glass, with a simple wood frame around you can use the thinnest glass at some €30/m2. >>2984238Silicone aquarium caulk? Super strong no microplastics and it’s toxin free because exotic fish are very sensitive
