I assumed the CFL because even though it had almost half the wattage of a HPS, plants need more of the blue spectrum during veg?

Go with the HPS, trust me you wont be sorry.

Thanks i think ill go with the HPS i think they have a bit of blue spectrum in them anyways

Not an option, to much heat :P

If you go with hps make sure you get a switchable ballast so you can run a MH bulb during veg. Although hps is good and powerful and shoots off alot of lumens. Its spectrum is not ideal for veg. Then when ready to flower switch to hps bulb. You could even run that cfl through veg then switch to hps during flower. Im surprised no one said that on here.

if your growing 1 or 2 plants then use the cfls. your practiclly just wasting money by using the hps until they flower. ive seen a lot of plants on here vegged with hps and they looked stretched out. i started my grow with 100w of cfl per plant. it was plenty of light (and u have more than that!) .......... OR you could start your plants off under the hps and do 1 with cfls (for veg) and tell us (with pics) wich one looks better.
