I watched the vid, most of it anyway. I skipped through since it was a bit lengthy.
The new room will be either 10X10X9'tall or 10X12X9'tall, not sure yet how long I'll make it and really depends on how my back holds up while building. There's vents that go directly to the outside of the building that I plan on using to pull air in and push it back out of for cooling the lights so this time of year everything should run pretty cool. During summer months I'll kick the AC on but for now I'd like to save on elec. I'm mostly concerned with odor control since things are gettin funky with the grow and it's only going to get worse.
