yep. that is my dilemma at this point, pup. my grow area gets warm with the lights on even with just the t5's. i have a vent to the outside that will fix that but even with a carbon filter, when i use the outside vent, the smell spreads. maybe need a better quality filter(tried 2 different htg supply filters). the tent i have is intended as a mothers tent anyway. this was never really going to be my long term setup but in all honesty, it keeps the fogeys flush with herb. however the grower in me wants to grow figuratively as well as literally. this will probably result in me retooling when i get around to my next indoor grow. maybe in the fall. i have a clone left (lost track of what it is - either buckeye purple or super buckeye) and i'm probably going to plant her outside and get some clones off her. right now she is pretty sickly with a temperature induced nute lockout. the basement is too cold without the lights, fans and dehumidifier going but i am not going to run all that stuff for one little plant. she is living upstairs with the fogeys for now though mrs fogey is not on board with that as a long term plan...
