Mr Grow It has a couple of YouTube channels. Check out garden talk episode 5. Don’t just watch this one - follow the links to welcome to the grow tent you tube stuff. His advice made sense to me. I am trying to grow organic and he isn’t, but he won’t try to sell you a new light or other equipment. If he doesn’t work for you watch a bunch of mr grow it stuff - most of the peeps he interviews have been growing for over a decade. One should make sense to you - there really are more ways to grow cannabis than there are growers.
