How important is it to keep the plants in COMPLETE darkness during lights off during flowering? Thinking of running some ducting with cut-to-size furnace filter out the vent hole on the side of the tent which supplies air right now. Will that be enough?
It's pretty important. Any leaks that can get in can cause stress on your plant which in turns results in a hermied plant. And no one wants that. You need about 3-4 times the size of a passive intake as you do your extraction. (I used a thing to cover my intake that I found on Amazon. Was a bug screen carbon filter shield that you could stretch over the duct work) As long as you can hit that number it shouldn't be an Issue friend! Happy growing! 👊
Well you did a very good job. It took me almost 2 years of trial and error to get it down. Mistakes will be made but they are necessary for learning.
CHEERS!!!
