I lucked out years back with getting the Masters Growers Course from @GreenCulturED and while there was a lot of review from my years of already growing there was also a fuck-load of new info and perspectives from other viewpoints which did really help me hone my skills much more!
Though I have the certification, I’d never actually call myself a “Master grower” because the plants can’t lie so I don’t need to and neither do you! (if you have happy plants lol)
OGM! “What’s in your garden?” OG web-series!!!
So that’s how you learned my tricks!
