Hey, I've been growing weed since 1975.....AND HAD NO IDEA WHAT I WAS DOING!!!
Seriously, I learn all the time thanks to the internet discussion forums, books, magazines and YouTube -MOST of which didn't exist in the 70's, 80's and into the 90's! Well, maybe it did, but all I knew about was High Time Magazine!
What I could have told you from all my years of "experience" would fill a thimble! (maybe). But, in the last 10 years, I have taken a crash course in the subject and now I think I get it...at least I understand enough to get decent results and to enjoy the process.
As far as weed growing knowledge goes, sharing is caring!
