Light intensity CFL's

here is the full bright light it is to much for my camera to capture it takes a min to get to the full brightness here it is in stages the guy that made it really knows what he is doing with all bulbs it is 840 watts at 80,000 lumens.

first proper CFL grow i've seen so far.

after all this, isnt there still the same old problem of light penetration, with no side lighting at all? Its a proper setup for sure, but i think if i had access to that many cfl's id have them surrounding the plants from every possible side, make the most of your light.

how much is it costing you per month to run this many bulbs?

with the hood full it depends on the way it is set up because the 6500 kelvin bulbs that you see in the picture are 26 watts and the 2700 kelvin ones are 42 watts so if they were mixed it would be 680 watts all 2700k = 840 watts all 6500k = 520 wattsthat was just a picture i took in response to some one saying they did not like it when it had the lights straight down with all the light bulbs in i have bloomed 12 plants using the bubble bucket method. 10 bulbs is normaly how i run it with two plants. i have had the best results the light is not wasted at all i have a light meter and this hood kickes ass it is very verstile in spectrum also having 5 bulbs at 150 watts is less lumens per watt a lot of people make the mistake trying to buy the highest watts they can find lumens per watt and kelvin rating is where it's at why run the same total watts with less lumens you know. so to answer your question it cost very little during bloom it pulls 3.7 amps 420 watts 12/12 and i veg 20/4 it pulls 260 watts my last plant i yielded 5oz dry.

The whole point about using cfl's, is that you surround the plant with cfl's 1 inch away from the foliage. With the wattage you're using, you could of had a decent HPS and got more yield. A lot of that light is being waste.

A mate of mine had less then the amount of watts you had and got 7 ounces.

Not bad though.

well using a HPS system at 400 watts is to hot and only produces 50,000 lumens for the first 100 hours some at 500 hundred hours and then it can drop as far as

10,000 lumens making it 40,000 lumens my light with 10 bulbs is 39,500 lumens at 420 wattsi think this is all so close that it will not make or brake your yield it is how

you grow also in HPS if you ballast or bulb blow it will cost you i think that has happen to us all you go out of town camping and you get back and the bulb or ballest

has burned out 2 weeks from crop if i loose a light or ballast that is just one and not much of a loss at all which means it is cost effective to maintane i think the heat and customization of the kelvin rating up or

down is the reason i use CFL's that and they kick ass i cant say that putting them around the plant is better then the way i have it set up now taking into

consideration that i have bloomed 14 plants with this light.

well, it still seems like even with all those lights you are still using much less energy than 1 HPS. The CFL technology sure is amazing, and only getting better. There are already loads of examples of amazing yields on CFL alone. The notion that CFL is inferior will soon be one of history. With some tweaking and experimenting, I think already more than possible for a CFL grow to match that of a basic HPS setup with the fraction of the cost.


EDIT: Frontier, you need to learn to use punctuation.

get some side lighting in there... like a 150w HPS or even some more CFLS.... nice grwo..

PS i thought people use CFLS for "budget grows" it seems to me that a much more efficent set up would be having an HPS on top w/ all those cfls as side lighting( some type of ventilation would be very neccesary)

no i sold all of my hps & mh lights and the ballast and the hoods it was all to much i am not a production grower with this light i can bloom 14 plants good size too i bought another hood from [email protected] the guy gave me trade in on my old hood it has a better angle you know i am sorry i know what the light is capable of and i will never buy another light system again you just dont need all that to get fat dank buds growing organic of course tho.

when you bloomed those 14 plants, what was the yeild (total and per plant)?

each plant varied but the ere was no less then 2 OZ per plant and no more the n 4 OZ on the airated root system growing soil but that is not a feet there are people that have grown more then that with less and hydro i choose organic because i am not in production and i prefer the tast less cure time also.

if you dont mind,what were the other details of your grow? im using a similar amount of wattage, (except mine is a 200W on top and then 12 23W cfls, and a 70W hps) and im trying to find what i might be able to yeild from a similar setup.

there is simpley no way to tell you it depends on your experience and many other factors any one who says diffrent is BS'ing you.

no less than 2 oz per plant under cfl?


bull fucking shit!!!!

no kidding those pics with buds look like a half tops

have you not seen the buds for less -CFL book you guys are to quick to hate on some one and that is not what this is about CFL's do just as good if you have failed in the futeur then explain you set up and mabey we can find some real flaws in it mabey i can help you reace 2 oz per plant.
