My last grow was start to finish w/2700k did fine in veg, though I think this time w/the 6500k they're growing a little faster ... think I'll mix them in as you saay it makes sense...Thanks!I do it as a matter of course, just a couple to balance the CFL spectrum. I kind of figure that if the Grolux HPS I used to use was full spectrum then it makes sense to add that bit of 'blue' in there but I have no scientific justification for that! I've seen plenty of grows start to finish with just 2700k's though so it will be interesting to hear replys here.
Thats what I was thinking might speed growth in flowering stage.Probably wouldn't hurt to mix them in now with yours.Ever since I switched to 12/12 with 2700k, the plant's haven't grown much. I think next time I'll put some 6500k in to help out. someone should do a study on how much...
