Sorry to answer your question i plan on having stones across the entire bottom section of the pipe.

And next question for the group. Everything weve discussed is for the flowering room. When i start off vegging....needless to say i need to start off in 3.75 in net pots......but in what type of set up? Ebb n flow? Would the roots be too large to safely transplant after 1 month of vegging?

It's something that we shouldn't be afraid to talk about.
I try to encourage the use of food grade products as much as possible.
