Just a thought...since mg's like heat, you might try a heat mat or some other heat source and then once they sprout, take them outdoors for light if your days are warm. Sorry if I have repeated somethings already mentioned on this thread. If your nights are still cool, bring them back to heat at night. Might keep them from being too "leggy". Also, I have started soaking and watering all of my seeds and watering seedlings with a peroxide/water mixture. I use 1 tablespoon of 3% peroxide in 2 cups of water. Supposed to help with germination and prevent damping off. Don't give up!
