******All mighty (( LIGHT )) thread*****

[Mr.Wicky]

For those with questions regarding CFL's inparticular the envirolite 125w both blue and red, I am growing just using those, 3xblue for vegative growth and 3xred for flowering. I dont have grows with hps/mh to compare with, however I have just entered flowering and I think the results in vegative growth were great. I think the true test will be how well they do in flowering as this seems to be a grey area on grass city as I cant find a grow journal that uses envirolites. My grow is here

I chose CFL envirolites because:

Cheaper to run
Less heat problems
Less space needed(height wise)
100% correct spectrum(no wasted light)
and I believe the lumen output per light is above 10k per 125w lamp.

what kind of light is this? and what bulbs would I need?

It is an incandescent bulb and is not really any good for growing MJ at all, its for plants that need little light, such as the orchid in the picture. If you want to grow MJ, look at either CFL's, HPS/MH or possibly LED's although LED's I am unsure of.

can I use CFL's in that fixture tho?

[ksw870]

i'm mainly looking for fixtures

CFL's use the same type of fixtures as incandescents, but you can get a clamp fixture similar to that at Walmart,or home depot for 6 bucks.

To my understanding i can get CFL's with blue specturm for veg and Red Spec for flowering??

Is this correct??

and if so

say i'm growing 2 plants would two 45 watt blue cfl's be good for veg and would 2 45 watt red cfl be good for flowering or when flowering do you have to increase or decrease the wattage

[doob3r]

maybe but im sure you wont be able to get away with one or two to get the full effect. id guess youd need to put it with alot of cool/warm white bulbs or whatever the standard CFL is, but more light is almost always better, i dont think you can give a mj plant too much light unless its like a seedling right under hps or something.

nice thread, how about some info on LED lighting

LOL toasty after reading a bit more you already answered my question to the T in this thread:

I'll hit up the hardware store this weekend for some of those socket plugs.
Thanks

In addition to being full spectrum, the light quality changes with the seasons as the sun climbs higher in the sky during spring, reaching its zenith in summer (June 21 in the northern hemisphere) and then declines as it heads toward fall and winter.

The amount of atmosphere the sunlight has to travel through absorbs various wavelengths of the visible spectrum and changes the color of light the plants receive. During summer the sunlight has less atmosphere between it and the ground so more of the shorter, blue waves pass through. In the fall, the atmosphere absorbs more of the blue spectrum, and more of the light is made up of the longer red waves of energy.

At least that's my theory.
