Okay, quick intro…Haven’t grown a plant in 30 years, and certainly nothing on par with today’s strains or systems. Long story short, I used to grow whatever decent seeds I could get ahold of using a basic fluorescent grow light and miracle grow. Stumbled across the ILGM site whilst carousing the internet a little bit ago and decided to try my hand at one of these advanced strains.
I plan on trying some blueberry autos, and for my grow area, I’ll be using an old basement shower that’s 3x3x6 1/2. After driving myself near batshit crazy looking at all the different lighting options, I’ve settled on a 400w HPS.
My question is about how much venting I’ll need. I was considering the possibility of hanging a carbon filter in the shower, run 4" vent tube from it, through a cooled reflector, and connecting it to the cold air intake of my HVAC system. I’m just not sure, with either the furnace or the ac only coming on sporadically as needed, will that be enough for the amount of heat that a 400w hps generates?
Is it worth trying that or do I need to just scrape up some more money for a proper exhaust fan?
