yeah you will need to extract the heat somewhere or it will acumalate, the oscilating fan only moves the available air, and does not cool the room at all, just freshens it!
with a four hundred watt lamp i use an extractor of 450 meters cubic per hour fitted to a cool tube!
i dont need to pump air in, as i extract a vacume is cuased drawing in the equall amount of air to where i want it!
if you seal your tent or grow room it will suck in a vacume! if you install vents where you want them or even pipes down the wall with holes in and the end sealed, it will "blow air" on the plants without any mechanical device! moving the plants and all! saves money! on needless extractors, however the room must be airtight or near enough!
apart from that i think ya have it all, except that in a neter square in SOG i use 36 plants not 6,
you would be better to grow your plants a little bigger and nip out the tips to encourage side limbs, and maximise your crop!
SOG works on large numbers of ;plants in a small area, not grown more than 12 inches high b4 flowering and maintained on one stem!
good luck with your grow zandor! cya in chat
