Its just a 8'' case fan mounted on the inside of the cabinet with a light trap vent on the outside and a box with a 4'' duct going to my hood on the inside. I can put it about 6'' and its stil cool. I have the room temp at 74 so my grow space stays about 76 and up to 78 closed. Im changing to 12/12 tonight.
Hey man, just finished a grow with Mandala White Satin & White Widow. The setup looks like yours too - First grow - Sea of Green style
Looking back at my setup (started next grow) I kind of regret not setting up a ScrOG. And I only had 9 plants in 9 square feet, so this might give you a better yield than me. Just wanted to let you know, but lookin' good bro.
Not as much as the WW - at this height, 22 grams or so per plant. It's crazy you're from FL, cuz when some of my friends sampled my MWS, they were like, "Holy shit - this tastes like the weed we used to get in Florida!"
