Ok, last year was my first time growing peppers outdoors and I had some pretty good success. Now I want to start from seed indoors but I have a few questions. First, for the heat source, should I buy a grow mat? I have heard that they do not supply enough heat for hot peppers? Or should I try a waterbed heater, I have one available? Second is the light source, would a shop light with 2 ge bulbs recomended for indoor plant use be sufficent? Third about the soil mixture, would miracle grow cactus blend be a good choice or should I go with something else. Sorry for the length and the questions but any help would be appreciated. I have some seeds on the way and need to get everything ready.
