ok i think i have the attic room dealt with but it is basically 10ft x 40ft crawlspace, with a max heigth of 5 ft all the way to zero heigth, get it? it is sitting in a crawl space hidden because of a room that was put in the middle of the attic... that room wall that creates this space is r-19'd, i r-19'd the exterior walls as well, and the floors/ rafters... i also caulked from the inside all visible seams to the exterior. it is vented by a grate on one wall that is about 1'x2' maybe a little bigger... and 8"x1' on the opposite exterior wall...

i have some of the pink 1" foam insulation board to put in the rafters above the grow space, as well as tar paper and black plastic vapor barrier...

i am going to put the black plastic over the entire area; roofs, exterior walls, floor, and main wall... not too mention tar paper over the r-19 on exterior walls, and floors.... i will create a grow space out of black plastic around my grow unit... i am gonna get a 400w but am afraid it is too short...

i live in the south east btw... think; memphis, charolette, atlanta, birmingham.

i know i need to get a fan for the whole space... but don't know how to run all the air shit,,, like which vent to fan.

for the space, i have 6" air ducting, an inline 240cfm fan,thermostat, and an oscilating fan

the house doesn't have central air... but one of the attic rooms has a/c and a heater...
