The hydrofarm humidity dome tray/w heat mat is this set up. I set it up exactly the same way as he described, but instead of sponges I use rabid rooters(sponge like material made of organic substances) that once sprouted straight into whatever. It also comes with a tray inside to separate the rooters from the water as in above. This set-up is only $25-35 depending on where you go. I know where I live its cheaper to buy this than to get every thing separate. I had the same issues as the original poster on the seed issue and since I switched to this I get awesome results.bassman i think i will look into building 1 them,
my germ rate was really bad to start with now i just put in soil in heated prop with no germ and have had better rates but still not 100%
and i love my cloners i build they stand me about £50 but thats to root 40 at a time
