The air for cooling the lights is drawn from outside the tent, through the light(s) and then back out of the tent. No tent air is involved in the process. You will need another fan and a carbon filter for air being drawn through the tent itself
Slowly getting set up I have a 6 inch fan with carbon filter to be used to suck air from tent to outside. Getting another fan to be used to draw air in but do I need a filter for the 2nd fan if its used to bring fresh air into the tent ? Or could I use the one 6 inch fan to be used for both bringing air in and drawing air out
No ... no tent air should be involved in the process so no odor should escape.
Thanks. Would passive air intake work on a 4x4 tent with a 6 inch fan
Put a short piece of rigid 8" duct through intake on the side opposite the exhaust duct and cover the opening with a filter. Hepa is ideal but not completely necessary. Most hydro shops sell 8" duct covers. You want the intake to be slightly larger than the exhaust so you can maintain negative air pressure without sucking in the sides of the tent.
Thanks. Will I need a carbon filter for the air cooled hood ?
you shouldn't
Awesome . Will have everything set up this weekend and post some pictures
Im worried about it caving in with the filter up top
Yeah that's all about grow style, I always ran 18 in a 4x8. 3 gallon pots of coco. Shooting for 3-4 oz a plant. The more you run in a space the less veg time it takes to fill it up.
6 plants will fill up your space pretty quick so you will need to hang it eventually or put it outside the tent.
Going to be doing 4 plants but yeah gonna connect to the hood and make some space
