nice little setup you got there humboldt!nice exaust fan setup too,inline centrifugal fans...are those daytons? and how many watts you have total there?looks like a 1000W hps and a 400W MH? is that all you have,or is there more?in either case i'm impressed.it's nice to see some people here are'nt wasting their time.i've got a simmilar setup,with 3 1000W HPS and 2 400W halides to veg with.same exaust fans as you ,if they're daytons.and your growing for medicinal use.that's really beautiful man. god speed!
