dustin, I ahve a question about germination, I have a flat with the sphagnum all ready just as your article states, however, I cannot provide bottom heat. It gets to about 105 in the greenhouse on sunny days, however I have a corner for my highlanders, where I grow N. inermis (just started a vine, yay!), and N. hamata, so I have two questions, first: should I grow these as highland, or lowland? second: do I abseloutly have to provide heat or is it jsut going to help the seeds germinate faster?
