heat problems and electreic bill problems solved!!!!

I have found that flouracents are the way to go! A normal 100 watt bulb pulls 100 watts and puts out 1800 lumens. Well a flouracent 100 watt puts out 1800 lumens and only pulls 26 watts. Using a 2x2 closet you would usually use a 400 watt hps. Well I tested the lights myself and put 4 100 watt flouracents on some og kush and N.L. #5 all grown in soil. The flouracents also cut down dramatically. If any questions or comments let me know. Also if you wanna check out my stuff i just have one pic of the og kush on my profile pic.

cfl veging is great.
i would invest in a 400whps for flowering.
you wouldnt regret it

I would put my 400 in there if i thought it would help but with my bills so high i doubt i will cause it has blown my mind how good its doing now. I know the cfls your talking about are blue spectrem but they also have red spectrem whitch i swoped to when i started to flower.

some people are happy with popcorn

you do know the 400 watt hps uses around 400 watts of power, but also puts out around 55,000 lumens.. you would need 30 of those cfl's to get the same amount of light. by then you're using near 800 watts of power. cfl's DO work, but you need more then just 1 or 2. maybe 2 per plant. they are good for getting them closer to the plants, or for small grows. larger amounts of plants love the super high lumens.

hid lights are great if the situation permits it...a lot of people rent apartments or houses and cant cut holes in walls or ceilings for ducting the heat hid lights generate...you can grow some nice bud with cfl lights...may not be primo bud that some people would rather have but it will still be much better than going to the local dealer buying it...if someone wants to grow with cfl lights that is their choice for their situation...they shouldnt be criticised for at least trying

it might not be the best in terms of running cost, but for a quicker cheap set up, or to invest a smaller amount of money in lighting and slowly expand, cfl's can work great. my plants are growing at a tinny bit over 1 inch per day under 100 watt cfl's. they are about 14 inches now and I just started 24 hours of darkness, something else cfl's are great for I currently have 8 cfl's over 9 plants, but I need to double that to something more like 15 150 watt cfl's for flowering. next grow, I should have a hps for flowering. anyway, my point, 1 inch of vertical growth per day under a few cfl's. they really are not the limiting factor. maybe it's just the grower and methods that limits the effectiveness of cfl's.

The incandescent equivalent onn the cfl's doesn't mean a thing! A 26 watt cfl puts out 26 watts of light period. 4 26 watt cfl's do not equal a 400 watt HPS bulb! 4, 26 watt cfl's put out 7,200 lumens, a 400HPS puts out 55,000 lumens.

I know I know.. no where near as powerful of light, but they do work, and they can work well! a 26 watt cfl supposedly puts out the equivalent of a 100 watt incandescent. that's what the number means. they usually do lie about it and stretch it to say it's brighter then it really is, but it's still what they mean. the 26 watt rating is the amount of power the bulb uses, that number really is irrelevant to growing. the 100 watt rating isn't exactly relevant either, but it's of closer relevance.

That really doesn't make any sense. You want to look at the lumen output, the watts are important to know in order to calculate your electricity bill. A 26 watt bulb uses 26 watts it does not equal 100 watts in any way, shape or form.

for an electricity bill, yes, the 26 watt rating is what you want to look at, but I was talking more about growing itself. the 100 watt rating is kinda proportional to the lumen output of the light. not exactly, but close enough for use on a forum. hid's are much more efficient, so comparing equivolent cfl watts to hid power usage watts doesn't make sense, but so many people do it.

the 100 watt rating doesn't mean a thing, period! It is the incandescent equivalent, a 26 watt bulb is a 26 watt bulb.

yay another thread of people arguing over whether CFL's are better than HID's
CFL's are better if they fit your application....HID's are better if they fit your situation....
I am growing in a small closet, so it doesnt take a genius to realize I dont want to burn down my house so of course im going to use CFL's, from seed to flower
If I had a full room, or a basement, I would use HPS duh, on movers, supplemented by CFL's near the plant.
I have seen incredible results with using only CFL's, they are ideal for small grows, and anyone with any experience could tell you this. BUT you cannot just compare straght HPS to CFL's because of course with the lumens/watts ratio theres no comparison. Its all about the application.

With a little experience, fluros work ok for cheap, stash growing. My last grown under fluros were 4"-9" buds and mostly tight. Of course fluros aren't enough to bring the lower buds much size, and thus, lots of lower pop-corn buds . . . perfect size for a quick bowl. For free stash, it's fine.

I know! haha.. how do we always get pulled into that same conversation time after time. all I was saying is that the 100 watt rating of a cfl bulb is loosely relative to the lumens. it depends if you're talking about the lumen output or the power consumption of the bulb as to what rating you want to use, the 26 watt or the 100 watt. the 100 watt rating doesn't mean much in terms of detailed specs, but it can be used to help beginners understand the amount of light they are dealing with. for instance, I have about 1200 watts of cfl lights in my grow room. I'm not really using that much power, it's more like 250 watts. around 2 amps while all the lights are on. enough light to flower a good number of plants in a small space, but still uses roughly half the power of a 400 watt hps, and less heat.

no wait, I don't think we're done arguing in this thread yet. here we go.. I'm gonna try LED's just kidding yo

There we go again, same old thing...CFL's v HPS Its up to personal choice, back in the seventies everyone was growing under flouros and happy to be doing so! You're all spoilt thesedays, but seriously quality will NOT suffer under CFL's but you got to pack em in and get the buds very close, yield however WILL be down but then we dont all need to grow buckets of bud..... 14 grams a month does me nicely thesedays.

And who said "popcorn" ?????? This guys been doing it for 26 years, CFL grow..... do you see popcorn here?

the lumens a light puts out is irrelevant too I thought, as lumens are only visible to the human eye...but I too have seen cfl's perform, maybe not like HPS, but let's compare a corvette to a chevette...

Old thread revived but here goes....


Well yes and no. Lumens is based on the green level (human eyes is tweaked for that) But humans can also see blue through red, so.....

Plants like the PAR range, which is part of the lumen spectrum, and then some.

Lumens is a baseline to gauge off. Intensity is subjective in a range of the spectrum. If you have a light meter for photography (for human perception) you can add filters, be them notch an/or band-pass to measure the PAR value of a given light/lamp.

Plants don't use lumens. They need intensity in the PAR range.
Lumens is intensity in the green/human tweaked range.

(also mentioned often is that plants don't use the 'green' part of the spectrum. I've never seen a PAR curve that fell off that drastically, if any, in the green range.),
