I have them underneath a 2-foot grow light and I'm doing them indoors. I planted them in seed starters for the first time we're growing them this year but now we start platinum in a bigger the two inch round cardboard like Planters to keep them in there without transplant too soon last time they all seem to die. I am going to try to keep them indoors. Thank you for your comment living life freely Ralph and Cindy have fun.
