Hi I'm setting up my new flower room and I was wondering about optimum Lighting and venting.
I have a can fan 33 combo(275cfm fan + carbon filter) and a 440cfm inline fan and a few 6" and 8" duct fans. I also have a 1000watt hps or mh a.c. reflector, bulb and ballast and a second (1000mh or a 600hps) r,b,and b.
I plan to use 2 passive intake 4"x10" floor vent cans on one side of the room and 2 lights and exhaust from the other side of the room.
I have 2 questions.
1. what combination of bulbs to use?
I want to harvest every month so the 1/2 the room will be on 30-60 days and the other on 60-90 days (no barrier between the two). so i thought 1000 MH on the younger plants and the 1000 hps on the ones going to completion(2000w total). or should i just run 2 HPS (1600w total)?
2. when i vent the lights which way is most efficient.
A. i pull fresh air from an existing 4"water heater roof vent thru the lights with the 440 and out to the attic. And pull hot air @275cfm thru the filter and into the attic. and the 2 passive intakes.?
or same as above but pulling room heat from the last hood instead of fresh air from the vent.
B. Exhaust the room inline in this order
filter-275fan-hood-hood-440fan- out to attic + passive floor intake? and seal up the heater vent.
C. Same as B. but with an additional active fresh air intake (6"duct assist fan)from roof heater vent to floor via 6"flex duct?
I live in San Diego so temps are around 70-80 tops. im having heat issues in my attic room so im moving down stairs to keep it cool under the big lights. This should do it I think? I grow in soil and i dont use co2.
Any input will be quite appreciated!
Thanks
