You know last night when I read your post I just skimmed it. Let me start off by saying that it sounds like you have done allot of work/research and I do commend you. Super Thrive, cloning gel and so on are good things. Let me know a couple of things before I try to give you some more advice, what does your spending limit look like? With about $100 to $150 you should be able to nock out those heat problems, you can spend less, but will have to probably be a little more experimental. Second question, is there a garden store around you that sales name brand equipment like Dayton, Vortex or Hydro farm?
When your ready to clone just ask and we will help.
