YAY!! I have stevia germinating. I didn't use a heat mat, but did keep them off of the wicking mats, so on the dry side. Looks like I have about 15 -18 of the 20 seeds I planted that have germinated. It appears that the fresh seed and less moisture did the trick. Cindy--they do grow slowly. Last year, after they had gotten probably 2 sets of true leaves I took them out of cell packs and potted them into 2.5" pots and watered with 1/2 strength fertilizer. They finally took off then, but they were still relatively small at planting out time. They seem to like being outside in the sun better than the lights; eventually, they got to be probably 20" tall.
