Growing Marijuana in Rockwool

Skuff

We’ll talk about ‘skuff’. This is the sifting of dried tops. When you sift your dried harvest first through a rough, then through a fine sieve, you remove all the remaining plant remnants, and get balls of resin (thus; THC) left on the sieve. It’s a fairly simple, but time-consuming job. Sift the dried harvest first through a size T-44 sieve. The THC falls through (with a little extra material). We have a T-77 size sieve under the T-44. You must carefully rub your harvest through the T-77 sieve. Then you have THC in it’s pure form without chemical processing
