Importance of Spectrum

I was curious how important the spectrum of the light is? I ended up with 83 watts of 6700k and 42 watts of 2700k. How necesscary is it to get more 2700k bulbs for flowering?

it depends on how much yield you are looking for you can do a grow entirely with one or the other but you will get better results with mixing them the blue spectrum promotes veg growth because it simulates summer sun and the red spectrum promotes budding because it simulates fall sun and tells you plants that summer time is over and it's time to flower you will be fine vegging them with the light you have but when you got to 12/12 you will want to get some more red spectrum

Buy as many of the 2 mixed as possible. Depending on which stage theyll be in longer go 60/40 with that spectrum. be more worried with getting enough light on them and keeping them cool!

Thanks for the advice, i think ill have to make a trip to the store soon and pick up a few more warm light bulbs.

not sure were you are from but lowes sells 6 packs of 2700k 23 watt cfls for $13 and i think its the same price for 6500k 6 pack
