Hey guys! my veg area is a 4x4 tent and im currently using a 400w HPS to cover it. i cant reaqlly afford to throw in more lights but i would like a better spectra then the HPS gives..
Would i be able to cover this area efficiently using 400w of cfl insted of HPS or would i not get enough lumens ?? Thanks for your time

You can buy a 400w MH for 28 bucks at home depot. You will end up spending more trying to rig cfl's.

Just add the cfls in with the hps, then you will cover the whole light spectrum range.

i cant afford to run more lights might be better to say? im still looking to get a good answer to what is better for vegetative growth. 400w HPS or 400w CFL of mixed spectras?

Heck for under $150 you can buy a Lumatek LK400 ballast and a 400w MH and HPS bulbs...just need a reflector if you want one...pretty darn inexpensive. I saw the Lumatek for $113 and you can choose your bulbs anywhere.Then you can use the MH for veg and the HPS for flower...either way MH or HPS for veg...you can't go wrong.
