Hey all hope everyone is doin well.so I just finished my first ever grow and everything turned out relly well actually.everything is hanging or in jars. Ill add pics later on tonight. But during my grow on days that were kind of hot (75+) my box got as hot as 90...not often but it did a few times, it averaged a high of 82 and low of 62. With the days getting warmer now I really need a re design.
Box dimensions
23"x19"x 5ft tall
I'm using a 400watt mh/hps,air cooled hood with a 4" fantech fan..I think about 150cfm pulling the air from the light out the top and pointed toward the window....and before I had a 4" axial fan for an intake and another 2 inch comp fan that propably did nothing...
So what I am thinking of doing is getting another 4 or 6" inline pulling air through a scrubber and out the top, my questions are...
How strong does the fan need to be to pull through a carbon filter and still create enough negative pressure for passive intakes to work?
And how big should the passive vents be? And how can I make the vents lightproof?
And is there any way to use one carbon scrubber for 2 inline fans? With ducting y's? Sorry for the flood of questions but its all I can think about and any help would be apreciated, ill add pics of the whole setup when I get home tonight so my rambling can make more sense.
Not sure if it matters but I plan to use 6" pots with about 9 plants sog style in ffof soil
