I normally do an inside/outside grow and wash my harvest, which is expected to look grungy. But my LAST grow was hydro indoors and I washed that harvest and it was almost as nasty. The other thing I notice is the flower stays fresh longer.
I store my harvest in a non frost free freezer. You don’t want anything with a defrost cycle because it will degrade the flower into a sleepy time cannabis (THC degrades to CBN).
BTW: here’s two of my journals…if you are interested.
