Ok, Roots look great, I'd say yes, its kinda emulating from the resevoir. Its not bad now, I dont have a vent setup for the room yet, just in the tent.
Plants, and roots look great, just noticed the smell this morning.. Now its kinda gone.. I close the door to the room at night because of cats, & just notice it in morning until I open door and windows..
Thanks for the reply SF..
