1968; A local friend and professional landscaper grew excellent bud each summer. Got some tips from him, he grew very simply. My friend and I would try and grow out a little. Some success, lots of losses. Also read some of the early hippy grow books, could have been Mel and Ed. 1970s I worked in UMass and they had a nice scince dept with environmental chambers and grow rooms. I learned some things there. When I moved to Vermont there were many guerrilla growers. And I learned a little there. But after all this time I'm still learning all the time, especially since being on the island.
