One plant in particular's sprouting recommendation is to grow it on @ 40 degrees for three months to acquire a proper foundation, and I can't think of any way at all that I can simulate that environment here.
You mean
after germination, right? I find this to be a very tough one too, the problem being finding a place in this climate that is cool but consistently above freezing, and also with light. (Dark, I can manage easily in our cold room, which I use for stratifying. However, putting a fluorescent light setup in the cold room would cause the water lilies and tender roses that are overwintering in there to start growing, which would not be good.) An unheated solarium or porch might be the answer... if one had one. Which particular plant is it? Maybe winter sowing will provide enough of a cool growing period, one can hope.
