I have a bunch of peppers that I've been growing under 315W CMH lights. They've been sitting 12-24 inches underneath these lights, which are pretty hot. I haven't been bringing them outside much, because we keep getting nighttime temps in the 40s, and it's a lot of pots to move. Do they need to be hardened off against the sun, given that they've been under hot CMH lights? I've put a number of other plants (nasturtiums, mint, chives, cauliflower) that I had under these lights directly out in the sun, and they didn't seem to be hurt. But I also care a lot more about these peppers.
