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
