T5 lights

I recently purchased a 4' 8 bulb T5 fixture it came with the 8 54W 6500K bulbs and I grew a very good and plentiful "garden". I now purchased 8 54W 3000K bulbs, my question is on my next go around when I put the 3000K's in for flowering what is the differnce in outcome going to be. THANKS!!!!!!!!!!!!

Well, according to a lot of research, having a spectrum closer to the 2500K area while flowering increases yield as that is the light that the plant is looking for at that point in its life. I use cfl's at the moment and I noticed a slight difference when I added 200 watts of 2700K cfl's during flowering. So, you SHOULD see a difference in bud density and thc amount. Best of luck to you.
For best results, I say buy a second 8 bulb fixture and setup both of the lights on the plants, grow a lot!

No I cant get another in the roon its just a 2'x6' and with 40,000 lumens thats perfect any more might by dangerous.
