Question on using an Ebb & Flow as a RDWC.

I was wondering if I was to adjust my overflow tube could I grow in 1 gallon grow bags full of hydroton and leave the pump running constantly and use it like a RDWC?

Maybe?

Any reason you'd want to grow in bags of hydroton?

I'd say, whether you want to try this idea or not, use XPS board and net pots. Lighter, cheaper, no algea - plus you won't have to worry about hydroton breaking your roots if you need to move the bags.

youd have to cover your flood table to keep light out
