@ Nana, You got me thinkin about the term "master grower." I always thought they use the term "master grower" way to often, and without any real criteria . Well, I just read somewhere that to be a real "master grower" of weed, you need to have 10,000 hours of combined ID, OD and green house experience. Plus, knowledge to manage staff and design a successful grow environment . Now we're talkin  !! Peace
