hello friend, I wanted to give you my input on the seedling issue, I myself use a flexible clip on desc lamp with a 60 watt regular utility bulb, that you would be able to keep 6"-12" over your lil flowery friends, I myself grow on a hydroponic top feed, and start my seed's in soil, and transfer them when I deem ready. Hope this helps, I do it every time, no nutrients during the seedling stage, the seed actually has enough energy resources to get itself to the vegetation stage without.
Have an awesome day friend
