Thread: 2700 vs 6500 question on wattage

Ok, i have a kewl setup here, and was wondering.

i have 3 lights

LEFT: 2700k 1700lumen 23watt CFL
CENTER: 2700k 2700lumen 42watt CFL
RIGhT: 2700k 1700lumen 23watt CFL


As you can see its all 2700k lights
and i know i can go start to finish with it.
but i was wondering if I changed it so
LEFT: 6500k 900lumen 13watt CFL


I know thats half the lumen, but
its 900lumen of BLUE spectrum.
would that be better to veg with
if i changed the left and right to those, and kept the center the way it is.


the space is 2sq/ft

13w seems a bit low. i like to use all 26w bulbs and i usually go 3:1

so 3 x 2700k to 1 6500k daylight or cool white

then you get the full spectrum


you could even change one of the 23w to a daylight 23w or even a 26w

Hey man I'm new to this as well. From what I underrstand its crucial to have mostly 6500k during veg. U can mix it a lil which is what I did but u want most of your light during veg to be 6500k. This will ensure u get the most from your plant. I have 4 6500 and 2 2700 on four plants. U mos def should consider changing some of them to 6500k

Nice ty.
What i did was put 3 bulbs in, 2700 lumens

in the middle i put 6500k and on the outside i have 2600k

its all they had ;/ but that should do for flower and veg.
plants are already a few inches now, wont change lights again
want to avoid stress, thx for the responses
