I decided to try it anyways. I still have more 2700k light bulb the I do of the 5500k. I dont think they are growing at a faster rate but I do feel like the crystals/tricombs are coming in quicker then they should. But then again it is just a CFL grow so we will see what happens. Like I said in my grow log...I am hoping for about 1-1.5 oz from each plant
