Hi folks!

zart, i strongly suggest you buy full spectrum floros and use those for the first 2 weeks instead of halogen... halogen doesn't have the right spectrum for any growth phase and is emitting a tremendous amount of heat.. perhaps thats why your seedlings are burnt.. ok, i think you got my point for halogen lights, its crap trust me

Floros will give you economical way to veg your seedlings till they reach 2 - 3 weeks, and then you can put them under stronger lights like Metal Halide or HPS (Sodium). Remember, keep the distance between plants and MH or HPS light lil higher for the first couple of days to avoid heat stress and stunt

Hope this help a bit

Good Luck & Happy Growing!
