The conditions are okay... It just takes a bit longer. My dries in the grow tent have been there for 8 days, they are getting drier, but it will still take another 2-3 days before I can put them in the jars. I only have a strong exhaust in the tent and nothing else. The exhaust sucks the humidity out, it looks like a vacuum from the outside. It's going pretty well. Morning sun on the black tent film is enough to maintain the temperature....
You just need a bit more patience. If you want to smoke something right away, 50 degrees Celsius in a convection oven for 30 minutes should make it dry, if not, repeat...
Have fun with your harvest!
