Compact Fluorescent Light Discussion

just a quick question i have a few 15w cfl's that have a rating of 6500k lumens and i was wondering what equation you are using to get this figure is it, 6500k divided by 15 watts, as for me this workes out to 433.33 lumens per watt or do you use the full wattage i.e 15w =75w output, such as 6500k divided by 75 watts= which equal about 86.6 lumens per watt

no...your taking the color temp dividing the wattage...what you need to do is take the lumens and divide it by the wattage....2000lumens/30watts=66 something lumens per watt

hey istayblunted...you don't want to use soft white..you want to use a "cool" 6000k for veg...and a "warm" 3000orless bulb for flower...got it?...good.....

what should i use for just the germination process until flowering?? and the bulbs that u described, is that good enough for just one plant or how many?? thanks in advance!!

SO here it is please let me know what you guys think.. Im growing in a 2ft by 2ft by 5ft space. Im using 1 105w cfl 5000k, 1 43w cfl 2700k, 4 23w cfl 2700k and 2 19w cfl 5000k. supernatural 20-20-20 supernatural 11-31-15
superthrive.. whole area is lined with mylar top to bottom.. my wuestion is should i chang these lights around . i thought of getting another 105 w and another 43w and doing away with the smaller ones or puttinf them on the sides any inputs

I have a box right now with a light T5 sunsystem 2ft 4 bulb fixture. Its working well for growing right now and the guy told me as long as I have mixed bulbs 2 red and 2 blue I should be fine for flowering as well. but I want to start another box and wanted to use Home Depot as my light source instead of 280 CAD for another T5 light.

I like the Fluros cuz the Heat factor so I wanted to use them will they be as effective as my Light from the plant store? Or should I look into getting a 150W Hps which i saw at home depot to mix with the CFLs

one more question I can use Cfls for both cycles Warm lights for flowering 2700K and Colder lights for growing? 6500K or should I keep a mix of them through both cycles? The Hps bulb is tempting and Im pretty sure It fits into a reqular socket 125V 660W As I have herd Hps is better for bigger buds. but if its going to mean more hassle from heat than I dont want to bother.

any help would be greatly appreciated. thanks

i read somewhere that if your using CFLs you shouldnt bother adding co2 because there isnt enough lumens for the plant to process it.
Is this true?

That is right. a co2 generator will not work with low intensity lighting.

Look for co2 soil suppliments (if they exsist in your area)

This CFL light stuff seems pretty good, Nice grows BObBong :thumbsup: . I have one question for you man, What type of lights are you using? The warm, soft, or cool light CFL? I was looking almost everywhere to see if you posted it already but i couldn't find it...
