Hello RIU!
I'm starting my first grow, and I just xfered from jiffy -> ffof and perlite (roughly 70/30). My concern right now is temps in the box. It's a 36x26x19 box lined with 6mil black/white poly. Got two holes, one for intake one for exhaust. Exhaust fan I'm using S&P TD100 inline fan hooked up to 4x8 phresh filter. I also added a 45 cfm to the end of my ducting to help out the td100 cause it seemed like the cf was restricting a lot of air flow. Not quite sure how efficient it is but temps settled down to 80F-83F with the 150w HPS running. Intake is a 45 cfm computer fan. So I'm sure you need circulation of air flow in the room right? So I got myself a 5" O2 fan for circulation, and I thought by adding that it would REDUCE the temps but it climbed up to about 85F~. My first thought was maybe just more space taken up which would lead to higher temps? (fans only 5" so its pretty compact). Anyone have any insight?
And one other thing about temps, it may sound stupid but I feel like I must know. So I measure temps regularly and the way my box is set up, the HPS is more or less in the center of it. So when I put my thermometer on the pot next to my plant, it gets around 83-84. But when I put my thermometer anywhere else in the box, temps are around 79F ish. Is this normal? Should I be worried? Thanks a lot in advance.
ONE last thing! I'm actually very new to gardening, and I transplanted today into FFOF, and I have a one gallon fabric pot, and to pre-water before transplant I put maybe one quart of distilled water? It seemed to be dripping a nice amount at the bottom so I stopped. Did I just flush out my nutes in the ffof?
EDIT: Was more like two quarts o.o
Again, any help would be great!
