It is a GE 400W putting out 36,000 Lumens ... with the color temp of 4000K . Guess my question is , would the MH bulb with 36,000 Lumens but a lower color temp (4000K) be better and have more growth or would the setup i have now be better with better results. The set up is just like u said ... Im using CFL , and they are putting out about 12,000 Lumens between all of them , but they do have the color temp that is best for Vegging (6500K) . Would the higher Lumens compensate for the color temp of the bulb ? I dont have the option of going out to buy a 6500K MH bulb right now (Because im going to buy a HPS bulb for flowering when the time comes) . So as of now , those are my choices. Some EXPERT advice would be awesome for this rookie.
