I understand that growing in a tank is really really stupid, but i think i found a way. I planted 6 seeds in a 20 gallon tank( dont ask how it works) in seperate planters. I intend on moving them to a different type of set up but for a few weeks while i get everything sorted out i want to keep them in there. I set up a drainage system. I elevated the planters and poked holes in cups to drain out excess water which is leaked to the bottom of the tank. i than drilled a hole in the side of the tank so water would leak out into a milk carton below the table, which i have this 20 gallon lizzard tank set up on. The main reason i have this set up is because i wish to cover up the smell and i cant afford a carbon filter. I however did invest in a top to the tank a while ago that has holes at the top and allows air to circulate. There is also a fan blowing air directly at my set up. The light is also located at the top of the tank. Tell me what i can do to improve this set up, and in a few weeks when my plants are biger and i have sexed them, what type of set up should i use. Thanks
