When you say balance of cool white and warm red whats your ratio? And when you the biggest wattage what do you mean by "biggest wattage?"

My ratio is 50/50...and add another red for budding, but I'm coming from the world of T8/T5 lighting, but if you don't like that ratio I have others ...lol just look to your favorite LED maker(mine is solarstorm USA) and adopt their ratios
CFL's are getting big these days, I saw a 450w cool white in my grow store the other day, but most are around 300w
..and yeah plants never get enough light ...lol

What is a watt? What is a lumen?
A watt is the measure of power consumption, and is the common way incandescent light bulbs are identified—for example 60-watt, 75-watt and 100-watt. When purchasing a light bulb, what you really should look for is lumens, which is the measure of light output. A 60-watt incandescent bulb produces about 800 lumens. A 13-watt CFL bulb will also produce 800 lumens, and it requires much less power. You know how most say we should look into wattage? This just came across my desk. Interesting. But wattage is good understand so that you know how to deal with it accordingly.
Dont want underestimate the power of it unless youve taking a liking to the fro and wqnt one...lol:peace: The part thats interesting is the argument that some say dont look for lumens look for watts. Others say look for lumens instead of watts. They both have important significance.

You need a balance of cool white(6500k) and warm red(2700k) understand kelvin is the color of the light, sticking to just one color will screw your plants up, I did a test recently and even I was stunned by growing a plant totally under cool white(6500k) was squat and flat the other warm white(2700k) was tall lanky and stretched...that said I germ under 4000k, called daylight and am suspicious, .. waiting on results ...lol
as far as lumens go study this up ...well worth the effort bottom line is get the biggest wattage you can afford,
ensure the kelvin is equal and plants never get enough lux ...lol

wouldn't 4000k be in the green color range?

5000k is your green. a lot of white led growers have moved more to the 3500k to 4000k for their grows and liking the results. i had a bunch of 5000k 23w cfls, and was wondering why my plants was going after my 2700k bulbs. seems they wasn't getting anything from my 5000k's. i gave them to the wife, and switched to 2700k to finish the veg..

I don't believe that's correct giggy based on the temperature chart someone else posted earlier on this post, but hey, I could be wrong...

maybe your right, when I looked at the chart again I see it's 4200 that looks like it's right in the green zone and 4000k is all white light....hell what do I know?
