Hey all,
I am nearing the end of my growbox build (see my journal here for the details) and decided to test the temps and humidity within the box before fitting my fans.
The box is located in my shed, which is in my garden with no type of insulation so the outside temps will affect the environment of the shed and thus, I guess would affect the box temps (colder the shed, the colder the box).
I opened the box up at 8:30am and I found that after 10 hours of the 4 85W CFL's being on with the box closed and the two holes for where the intake and exhaust will be situated, the temp was 73 degrees and the humidity at 41%. From what I have read I would imagine that this is pretty much ideal and so I was wondering whether I need to install the pc fans for the exhaust or the intake?
I am worried that if I do install them then I will end up lowering the temp and this is not going to be great. The outside weather is unpredictable where I am as it has been raining non-stop and been rather cold for the last 2 weeks (10 degrees) but for the next few days the temps could rise to 21 degrees and so I think this could have an effect on the temp of the box.
I want to do some more testing and so I am going to put the lights on the 18/6 cycle that I usually would and then go in regularly and check the temps. But back to my original question...can I do with passive intakes/exhausts or should I fit the fans?
