I have a 8 bulb T5 just completed the 3rd week of flowing. Everything is going great. When I switched to flower mode I replaced 4 of the lights with 3000k. I have a few more bucks to spend should I bother switching out the other 4 bulbs to 3000k ?, or just keep it with 4 and 4?

I also am using with it
3x68 watt 2700k cfl
3x27 watt 2700k cfl
1x250 watt 2700k cfl

Thanks in advance

what i mean by diminishing returns is there is a point where you get less for the extra light, so if your only going to increase your lighting by 1200watt? out of..i aint adding up your current wattage, you might not get all that much more for that extra bump, money might be better spent on another cfl? or maybe an LED ligtht just to mix up your spectrums,

i am not adding any light I was asking if I should switch the 4 bulbs running 6500k to 3000k like the rest of them

I would only switch 2 of them, but I prefer a mixed spectrum in flowering. 2 of the 6500k/6 of the 3000k is a nice balance.

Yeah that's what I was torn on, I know a mix is a good idea I just didn't know if I was still a little 6500k heavy. thanks
Anyone else share the same opinion?

i use an 8 bulb t5 fixture as well and i use 4 - 6500k and 4 - 3000k during flowering. seems to be doing alright. i also use a few cfls of each spectrum. you can see how theyre doing if you follow the link in my sig.

stick with the 6500 K in there, they produce more plant sugars = more resin and will keep your plants shorter, I've seen a grow with 75 % 6500 K that was beautiful.

Thank you frmrboi, I have often wondered by looking at this chart if the color temperature of an HPS is what really gives the tight buds when growing and not so much light output like many suggest. That's a different discussion tho.
