No frost down here last night, but I was riding the edge of it ........ bet you guys from up North felt it though ! Top of the car had frost, but no plants in the area had any whatsoever. And looking like temps are beginning to climb back into the upper 60's and 70's real quick here. This will really push them into the final weeks where they start to fatten up and possibly lend some nice fall colors into the buds. Although I have been insect free with every plant actively tended this season, these cold temps also serve to stave off any members of the insect population that would prey upon my plants and really dampens down any leaf spot spore production as well.
Things are a-ok here and this grow pushes forward for the next couple weeks and into October hopefully. A lil rain seems to be on the way next week, so I will have to monitor that. But no mold at all this year. Things appear to be under control as far as that goes. I attribute that to a dose of Eagle 20 in preflower, really boosts the defense against mold well in advance. This coming rain will be telling.
Thanks for the questions and I hope I mostly answered them indirectly. I only smoke what I personally grow, ever. So a small branch broke off of the shiny with trichomes NL and I sampled some early bud. I am very stoned !
