im gona take the hps out till i get a bigger blower i tryed inline blower from meards it wasent any better than bath fan.Just to much of a pain in the ass to keep the temp down
The bathroom fans vary a lot in cfm's, for the $20 ones at 50 cfm to $150 170 cfm (bathroom fans) There are a lot of them in the 70 cfm range. My guess is that you will need at least 70 cfm. You will want to move it to the top eventually when the plants get bigger. Looks like a great cooling idea there Is is keep the temps down now?
Well 2 of the three large plants was male and as for the babys there not showing sex yet new blower is in mail so i started working on my new grow room 4ft x 4ft x 4ft heres a pick
Its my scrog box i guess i never said that you will see if i ever get time to work on it. Screen will be going after i finish panting and running the duct work i gona start using dry ice i found out i can get it from work
