New to this. I would like to grow 2-3 plants.
My closet is 2x (deep) 6x (Length) 8x (height).
I have mylar on all the walls and I have completley sealed the doors with weather stripping so its fairly well sealed when doors are shut.
I have purchased a 400W HPS light with a sunlight sun tube reflector.
For ventilation I have the following:
Intake is a 4" duct coming in from ceiling (far right side of closet ceiling) and run down the wall to the bottom of the closet. It's mostly passive but it is tied right into my AC insulation/ductwork so it gets some fresh air pushed in when AC is on. Not too much, but enough to feel a draft.
For exhaust I have a 110CFM bathroom fan installed on the other side of the ceiling (opposite end from the intake duct work) which I tied into a programmable digital switch. This vents into my attic with 4" duct which ends in a 4"/6" carbon scrubber, so I think I have odor under control.
After doing more reading I am starting to wonder if this will be enough ventilation/cooling for my space and a 400w light. I have been keeping a digital thermometer in the closet right now and its been about 72 to 80 degrees, but I also haven't been running my exhaust yet. I am guessing the exhaust will drop the temp 2-3 degrees.
I am also going to put a small oscilatting fan in when grow is under way which may help cooling a bit as air is moving around more....
Anyways my general questions are do you think I have enough ventiliation?
How many degrees do you think a 400w will raise the temp in that space?
I do have the option of leaving closet doors open if I choose to but I would have to keep the bedroom door closed and I am not sure if that would help/hurt the odor and the exhaust system I do have in place now.....
