I've always wanted a heating pad, but I'm to cheap to buy one. I raised my lights to take the pic, but it's only a single 200 Watt 6500K CFL. Notice how when the seeds first sprout they don't stretch, instead they stay very compact. I don't have a fan, I'm not feeding them anything, no pre-germination, and I'm using city tap water. Even as my plants grows the spacing is just about perfect. To me, this is how they should look. These are in one gallon smart pots. The lights hung 4" to 6" away.
Some seeds were tiny, some were big, some sank right away and some floated. None of that mattered because they all look great. Indicas and Sativas all getting along together. Really the only thing special I did was add a thin layer of coir after they sprouted, and this was simply to prevent bugs from having a place to lay their eggs.
