**HPS 2200K vs T8's 1850 K and 9000 K**

[420caregiver]

I have a range of differen spectrums that i can use T8's (1850 kelvin) and 6500 Kelvin CFL and 9000 Kelvin T8's


I would like to know if 9000K is better than 6500 K For Vegging or is their any better ranges in kelvin?

For Flowering 2200 K or 1850 K ?

the standar i see using here is HPS and MH i use these i have a 600 MH and 1000 HPS what do you recomend?

Has anyone seen / use 1850 K for your growth or anything above 6500 K?

The 600W MH and 1000W HPS bro go with what's tried and true unless you want to experiment. But the 600 with the 1000 sounds like a sweet setup to me.

Thanks for your advice and i will!


But my main questions is can the different Kelvin's make a differents in growth?

As a general rule you want more of the "blue" spectrum during veg ~6500k and more red during flower ~3000k. 1850 seems really far off the end for a CFL. For that matter, the lowest I usually see a T8 is 2,700k.

i Thought i could get a t8 for 1850 so i wonder if i get closer to the blue (6500 +) or lower than a 1000w HPS at (1850 T would this benifit my grow at all?

So mainly my Question is if i get
a bunch of t8's and cfls at


1850k and 9000k would these 2 mix be better than a

2000k HPS 4000k MH Kelvin wise? or should i not waste any time with different kelvin?
