Why do so few use the 2700k led chips? I'm going to order six vero 18 chips next week and seen the 2700k while looking at the 3000k & the 3500k.
 
I use 3500k in one tent and 3000k in 2 other tents, and have no clue which performs better. I have a feeling it doesn't really matter as much as we think as long as there isn't a crazy amount of blue. (it would be great to see someone experiment with a 5000k 70cri from start to finish to see if it's really not good for flowering. What if we're actually missing out?)

I'm using 4 x 5000k and 8 x 2700k vero18 @1400ma in a 1mX1m area the plants finished veg yesterday and look amazing if anything the growth was very compact no stretch at all I ended up moving the light 3ft above the canopy so they would stretch

I'm wondering if there is any beneficent to doing it like this as opposed to shooting for a 'middle of the road' spectrum.
 
thanks everybody, i just knew i never seen many 2700k on the led side. i have always ran a mix if lights and have talked to churchhaze on this project. captainmorgan i have watch most of your grows dude you got the green thumb. nice plants camandcandice.
 
i'm leaning to the 3000k for this project. the first round i'll use it as veg and bloom, but by the time it's done i'll have another setup for veg. i'm down sizing so my new space will be a upright freezer. it's 24" wide 19" deep 54" high if i remember right. i thought about a mix of 3000k and 3500k but with 6 cobs i think i'll be better with all the same.

Seem like another one of those hippy myths to me. All the research I've seen, says cool white is not optimal for anything but human vision.

And I imagine it came straight from the CFL Buyers, (make profit on you) Club. :)

This really opened my eyes. Science, not myth.

In the meantime, as I mull over the details, have a gander at this little gem I stumbled across:
