I upgraded to 6500k vs. the 4100k. *What results can I expect to see with my VFTs. *I am using a total of six lights with 2,700Lumes each and a co2 reactor. *With the 4100k, I seemed to get good color but growth was very slow. *However a co2 reactor seemed to help some. *I hope these lights will produce healthier plants.
My guess is that the higher temperature will cause the plants to have more compact growth. *Lower temp lights cause more flowering from what I have heard.
best of luck,
