I'm going to bring his thread back to life. Fucking sweet info here...the problem is, I'm retarded and still don't understand a few things.
I grow in soil, so I don't need to chill a nute rez, just my 5x5 gorilla tent. I'm running LED so I can't just cool the hoods. I'm assuming a 1/10 hp chiller, with the icebox fan thing and a submersible pump(maybe 550 gallons/hour) are all I'll need? Maybe a 20 gallon tank for the water?
If there is something I'm missing, or if there is a cheaper DIY I can use(please be specific with diagrams if possible as, again, I'm retarded) please set me straight. This tent will be fired up in a couple weeks, so I've got about 2-3 months before the first flower in there. That's really when I'm worried about the heat getting a bit crazy. Thanks in advance to all that offer advice! Peace
