jeez guys i dunno how you keep temps down. my cab isnt as small as some others. 18" X 30" X 60" and im constantly around 90-100degrees. i got 1 X 150hps, 1X42w cfl, 1 X 60w cfl and a 24" T5 fluro tube. thats about 130w of CFL on top of the hps. i got my scrubber with a 130cfm fan thats exhausting out of the box (scrubber is in the bottom of the cab though and its connected by duct hose so the air is being pulled from the bottom portion of the cab) the only exhaust is whats being passed through the scrubber cuz im paranoid, but i realize i need more exhaust. i also got a 100 or so cfm fan blowing around at plant level and smaller 80cfm above the 150. i just got the hps and added it to my previous arsenal around 4th week of flowering. i have been watering more to make up for the heat, it doesnt seem to be bothering the plant (only got 1 now, 1 died RIP)
im growin The Church also, just finished 5th week of flowering and its lookin good
forgot to add, grown in soil (pro mix) and all organic
