i sold my stuff and and cab but now the new owner wants to build a new cab, but has some questions before he starts building it.
1x1x2m cab and 400w hps with digital ballast and cooltube. Is this lamp ok to cover this area or 0,8x0,8m would be a better choice for the setup? and how many plants would be optimum? i was thinking about 5, then they would have enough room to grow and develop branches/tops what you guys think?
he also has 1x250m3/h inline fan and 2x160m3 "computer fans" but not plastic, those have metallic cases.He was thinking, maybe the bigger inline fan moves too much air and maybe RH would get too low?(before he had 0,9x0,6x1,5m cab, RH was always 15%), And so, maybe he should replace the inline fan with computer fans, so that one would be cooling the lamp and the other would be connected with a carbon filter and also move the air through cab?
i think it's all right now; waiting for responses :)
