Nice. Here's what I'm working with.
4x5 veg 3-4 18 gal rubbermaids
5x5 flower -1250 watts led,
Acinfinity ventilation system. If I needed it I have a portable 10000btu AC.
2 31gal rubbermaids
2 18 gal rubbermaids
I need to keep everything inside the tents as I'm severely limited by space.
I'd like to do it right and be able to autofill the resevoirs if I'm away for a couple days. (Unlikely)
It's being built as a single cola SOG system. 16 sites with room to walk around.
My main concern is cutting holes in the sides and them being solid and no leaks
I can do pvc no problem but, what about rubber grommets with barbed T's?
I guess I'm thinking just bottom recirculation and stones in all my tubs.
