Well Im not to worried about the air pump. One of us is always home once a day and the feed line coming in agitates the water quite a bit if the pump fails. As far as hanging bulbs vertically, I too have seen it done well. For some reason I am just really skeptical about the results. I like aircooling and being able to cool the lights without taking CO2 out.

I think we are fairly decided on the 4 rows of 4 because the room is essentially a square and this would enable use to get the most equal distance between plants. I dont know about the drip though. I am not concerned with water temps at all (in fact I know with just an A/C it would be fine because the outside temps are around 50-60 and shady, but we have a 1/3 hp water chiller which can easily bring temps down over 12 degrees F). The only time the temps will get high is during the CO2 and the chiller will keep things nice then (were going to have a problem getting temps high enough for proper CO2 absorbtion cause its so cold but the dehumidifier will hopefully take care of that).

I feel like we have almost everything taken care but I am always open to opinions and looking for suggestions.

Bluebear, I also feel like 2 plants for 600 digitals is excessive. The 600 digitals really are putting out nearly the light of the 1000s magnetics. I mean I know they will be trees, but wow. I think we will do a lot of LST because my roommate is afraid to do screens for some reason. Trying to convince him otherwise. I think right now the most ideal choices are Purple G and Purps, the Grapefruit might have to wait.
Racerx Reviewed by Racerx on . Recirculating DWC - # of Buckets / # Lights I normally like to figure stuff out on my own without asking questions but this is relatively uncharted waters for my roommate and me and we dont have a lot of time to mess around. I am looking for some input on the amount of buckets and lights to do with my new recirculating DWC hydro setup that is currently under construction. A new room has become available to me and its time to put it to use. The plan has been to do a recirculating deep water culture (DWC) setup with between 8 and 16 Rating: 5
