Thanks for your answer. yeah i only had the angel on my mind, i forgot that the water would just naturaly push it to the drain, Which in my system , might actually have anoter pvc tube, going direct into the bucket..so there isnt any spillege:S
i was going to start a new thred for this question , just wondering if you could answer it or just give me some opinions.
im growing in a aero that will be 3footX2foot. 3 tubes, each probably 6inches? so that they can hold more root mass...and i was going to put the pots closer together, so although i only have 36Inches per pipe ( 3 of them ) i would still place 4 pots in each, leaving a 3inch gap between them . do u think it would work ?
