What kinda lights you got?

Shopping for those now trying to decide. I'm going to get some cfls, I'm still just unsure about how many I need to get the proper amount of lumens for 4-6 plants.

The dual spectrum lights from that same website vegged 5 plants for me just fine then i switched to hps for flower.

Wait, I'm growing in soil, this says it's for hydro. Can I still use it?

Oh, I don't know if they work in soil. look at these,
