Well he's a good teacher !
Here I'm not trying to teach a whole bunch really, I'm more into getting people to research and to think for themselves. THAT is how one learns to read plants IMHO.
That's probably what Elvis got you to do as well I'm guessing....
For me it's impossible to teach how to read plants and also how to defol as you must be able to read plants to defol. Everything else could be spelled out in black and white.
I could list off do A, B, C, and don't do X, Y, Z but in the end what would a noob learn ?
Nothing for their next go round methinks....
