i dunno if everyone is an amateur, but i know i am...this is my very first grow. i tried so many times in the past, and they don't make it past the cotyledons. but now, i am armed with all the FAQ in this forum, and other ones. plus feedback from experienced gardeners. Cant get this info anywhere elseeveryone here is an amateur? i'm not. mid-atlantic. cannabis is fine fine fine down to the upper 20's no problem, no problem whatsoever, it is not going to curl up and die, not a mature plant, with a little frost, i mean it can get totally frosted and still be just fine. but as the temps go down down down, to those upper 20's what happens is the growth stops anyway, and the cold, damp increases chance of frost and it is time to pull them. i will keep one out until the very end!
