I am growing Purple Haze outdoors in Massachusetts. My best sun is in the front of the house, facing the street. I have four plants in 4 gallon pots that I move through the day to make sure they are in direct sun as much as possible, as well as out of sight as much as possible. I also have 7 plants in the ground behind the house, where they get only about 4 hours of direct afternoon sunlight each day.
All are in flower. The sunny plants in pots are larger, and as flowering progresses, the fan leaves are turning yellow en masse. Only the sugar leaves are staying green. I think they are root bound, but as I need to move them, I didn’t want the pots to be too heavy and here in mid-flower, I don’t want to disturb them by one more transplant 4 weeks before harvest.
The plants in the ground are all nice and green with just a few lower leaves turning yellow, like they are still in veg stage. My theory is that the lack of sunlight is making these plants retain their chlorophyl later in the season. The segments on these leaves are very fat, I think for the same reason, to maximize sun absorption in their mostly-shady environment. These low-sunlight plants have decent flowers and pretty good collections of trichomes.
Anyone have thoughts on planting in pots with good sun versus planting in the ground with limited direct sunlight? I am trying to make a plan for next year.
