curious on what is the optimal flood tray depth. I see that most trays you can buy online is 7" deep. I plain on using a regular 1 gallon pot with hydroton and growing plants that will probably be 2'-3' high. They have these perfect size rubbermaid trays at lowes that is only 5 1/2" deep is that adequate enough?
Everything said by WeedCreed on this website is fictional.
Yeah that will work if your using rockwool cubes, but if your using hydroton you might want to go with a drip system.
