I watch a lot of YouTube gardening videos, especially with tags such as: PNW, Outdoor, Organic, Cannabis, KNF, etc. I'm subscribed to a lot of Cannabis-specific ones:

The Emerald Cup's YouTube channel also has some great videos; some expert guest panels with Q&A from prior years.
There's a lot of info on non-Cannabis gardening/farming channels too; soil science and plant biology, root/canopy training, propagation, organization, companion planting, IPM, DIY projects, etc.
Like, I watched some videos from a tree and shrub nursery and they explained how they start their trees and what specific things they do to give the saplings a vigorous root system. And some of those techniques I had never seen applied to growing Cannabis, but could be. (An experiment I may try, for example.)
