Great point about the debris and keeping them off the ground. Mine are on a deck, but once the flowers get thick, hard to keep out the moisture in the Pacific Northwest. It's been a crappy Sept this year. Last year, no rain and warmer temps through Sept.
My new rigged shelter in attached pic.
It's been terrible this year. Last year no rain until October. I looked at some pics of last year, I harvested 2nd week in October. That's not going to happen this year. My Sativa could use another month, sadly that won't happen.
Good luck!
Lots of rain in the Northwest this year. I'm in Seattle and trying to ward off chopping them for a few weeks.
I concocted this cover (see attached). I clipped it down to the lip of the pot with little spring clamps from Home Depot. It worked pretty good, though I'm sure the plants hate it...
