Grow box will be: 2ft x 2ft x 3ft high
Required lumens @ 5000/sq. ft = 20,000 lumens
I will be using CFL's for the grow box. It will also be holding 3 fluorex 65w 6500k (6825 lumens each). Those will be swapped later for 3 105w CFLs 2700k ([FONT=Verdana,Geneva,Arial,sans-serif] 6720 lumens each).
The questions I have are fairly simple about box design, however I wanted to get verification from everyone else who has input.
I have a carbon scrubber I am going to place at the top of the box with a 110cfm fan attached. The fan going through the carbon scrubber is a true 60cfm fan. This is still more than enough to evacuate the 12cfm area 5 times over in a minute. However... because this will be a VEG and FLOWER box here are the ventilation questions...
1) how many passive intake holes at the bottom should I place to ensure proper airflow without creating too much of a vacuum effect from not having enough intake air?
2) How big should the passive holes be? I assume the fewer holes the better depending on size.
3) How can I have unrestricted airflow and not allow light into the box from outside?
4) Would I still need a small fan inside to circulate air considering how much will be exhausted per minute in this small area?
Lighting Questions:
5) Can I add two smaller 23w CFLs during the veg. phase without posing any problems? Or should I stay with just the typical 6500k bulbs only?
6) Would a reflector be necessary for this size box? I will be painting the entire area with a flat white paint instead of messing with mylar.
Thanks! I might have more later.
