Toker, you are exactly right. That's why I asked a very rudimentary question that even a beginning grower would never be stupid enough to ask! Because I know that I don't know it all, and when I saw the vast experience of this sites users I thought there might be something I could learn. As to the quality and potency of my stuff, all my friends that use clinic stuff say mine might not look quite the same, but it does the job just as well, and often far surpasses.
Korn, please see above! Thanks for your attempted insult, I just had to laugh! And it's 40 years of growing strong.
