sorry to hear that.... i mean about th computer. that sucks
So.. Whats up Bob?? Dry yet? Have you smoked any of it?:)
Yield, etc.?:)
all I have to say is..... Brilliant!
Please explain or show how you handled the odor.
I have about the same type of space I am going to be working with. Starting to gather materials and info. thanks! your thread is giving me alot of info!
Compact Fluorescent Lights
I'd like to talk about these lights.. I've managed to complete a number of nice grows using only CFL and incandescent lighting. Those that know my grows will know that i have managed to yield quite a bit of porduct using just these lights.
So i'd like to talk about them
Have you any questions for me? concerns? I'm currently in the process of making a FAQ on these lights and would like to know what kind of concerns or information people would like on these lights before the FAQ is put up.
These lights are simple to use, simple to install and very effective for the "amature" grow.
So.. Let's begin!

These are links to past grow "reports" i've done with CFL based grows. You will be able to see what kind of yield i got, how these bulbs can be utilized properly and what kind of results you can get with them.
CFL's are great, and with the right spectrum are perfect for growing.
I used 1 15 watt, yeah, just 15 watts to veg a 1 foot high plant, and it was fine, no stretching or anything.
Btw, incandesants dont promote vegative growth, only stem growth, but thats only in high, not thickness, so realy it promotes stretching and possibly the plant falling over, so incandesants are ultimatly useless.
Exellent grows bob. cfl, i have never used them i use fluro tubes for beggining of veg. I have heard great things about them from mobay.They solved hiS heat prob and his yeid was exellent so it will be intresting to follow this thread and i will read up and see if i can throw a couple of questoins your way thanks.The Postman.
Bob is writing up a great FAQ for us so please be nice with your posts and keep that in mind.
Thanks Bob.
incandesants whats is this like a regular everyday bulb or are these the CFL's? only cause you mentioned LIP that it only promotes the stem growth like higher not so much thicker, why is this?

hello everyone wassup bobbong actually when i first became intrested in cultivation i spent several nights just reading over previouse grow logs and yours were definietly insightfull i mentioned it several times in previouse post including my first grow log under bkskillz which i recently completed and a continueing i attempted to complete growing with cfls but became sidetracked and progress hungry and switched over to 250w hps but i aggree completely theres relativly no better alternative for the cost friendly grower then cfls and thus far a combanation of cfls and hid's seems to work wonders as well especially if you mix up the kelvins such as my grow which consist of the 250w hps then 2 55w 5000k(blue spectrum) cfl's...i also have several 2700k(red spectrum) cfls but i tend to use those for the week prior to my clones going under the hps...moving on seeing as you did ask for questions i'll start it off with a good foundation point im sure youve already included the brake down of the kelvins chart in your faq(which a cfl faq is way over due in my opinion) but for those first timers can you brake down the spacific differences in light spectrums and there end results with that said great to see you posting in the cultivation section and safe growing!
Cool Bob Can't wait to see that FAQ and start a CFL Grow seen the pic's from your last grows and they looked Great most ppl would prob want to know what type of cfls and how much is need per Square foot of space and that type of soil when to switch to diffren't specturm lights for flowering what nutrients you use thats about all i can think of for now :)
you can use the same lights from what i heard it's just a change in the cycle
hey bon in your threads i noticed you had CFL's and regular bulbs, don't they just stretch the plants and provide no lumens? what is there purpose
Yes, incandesant bulbs are your every day household bulbs, that produce NO lumens, and are the wrong psectrum, therefor rendering them useless.Quote:

Hey guys, thanks for the input.. It's helpin make this FAQ come along nicely.Quote:

I found this in my CFL research, thought it'd shed some light on the incandescent issue.
""In a 120 volt, 100 watt "standard" bulb with a rated light output of 1750 lumens, the efficiency is 17.5 lumens per watt. This compares poorly to an "ideal" of 242.5 lumens per watt for one idealized type of white light, or 681 lumens per watt ideally for the yellowish-green wavelength of light that the human eye is most sensitive to.
Other types of incandescent light bulbs have different efficiencies, but all generally have efficiencies near or below 35 lumens per watt. Most household incandescent bulbs have efficiencies from 8 to 21 lumen per watt. Higher efficiencies near 35 lumens per watt are only achieved with photographic and projection lamps with very high filament temperatures and short lifetimes of a few hours to around 40 hours.
The reason for this poor efficiency is the fact that tungsten filaments radiate mostly infrared radiation at any temperature that they can withstand. An ideal thermal radiator produces visible light most efficiently at temperatures around 6300 Celsius (6600 Kelvin or 11,500 degrees Fahrenheit). Even at this high temperature, a lot of the radiation is either infrared or ultraviolet, and the theoretical luminous efficiency is 95 lumens per watt.""
So from this we see that Incandescent, like LIP says is almost useless. The percentage of useable lumen per watt ranges from 12 - 35lm/w Compared to practically any other type of lighting this is poor quality light. CFL's give us about 45-65 lumens per watt.
You can see there also the Overall Efficiency which makes it obvious that for 100watts it's really just not worth the heat and energy. However...It's still better than no light at all.
Incandescent than, should only be used as supplemental light...and that is if you have no other choice.
The temperature of light varies from blue to red. Blue produces the most amount of growth...it is the light that plant utilize the most and is what the plant requires to produce as much photosynthesis as possible. The kelvin temperature for your plants will range from 5500k(blue) - 2200K(red). Fluorescent lighting can be found in varying kelvin temperatures to suit your specific needs. There are different "names" for these bulbs, such as "warm white", "soft white" and "cool white". "Warm white" being much lower on the kelvin scale, thus giving off a "warm" or red tone to it. "cool white" being the opposite of "warm white" and "soft white" being between the two to give a combination of both. Do not use "Soft white" this is between the red and blue spectrum, specifically designed to be easier on the eyes for some people. Often the lights in your lamp or kitchen fan will be "soft white". Plants do not see the middle of the kelvin colour temperatures.. yellow and green will not be seen by the plant...hence the whole Blue/Red conversion when it comes to flowering.Quote:

You will also be able to find many places online that will shop worldwide with reasonable prices...
Online maybe the best source for many people for these lights.. you will be able to find exactly the colour temperature you'd like (from 6000k to 2200k). Often the bulbs you find in your local hardware store will not be as good quality as the bulbs you can find online. These stores will not carry bulbs with specific kelvin colours.. rather advertise them as "warm","cool" and "soft" white.
These bulbs will range from 10$ -25$ and up(USD) depending on where you get them from..and the size you wish to go with
NIce work BOB,
I have just finished the first draft of an 85 page book. It is the life of a single mango plant that was grown under CFL lights and harvested 3 ounces in 70 days.. started from seed.. Each page has a picture of the plant and a description of what needs the plant needed on that particular day...
I am going to start a thread soon requesting pictures of other CFL grows. I want there to be a few pages in the back of the book with many different CFL set ups....
you da man BOB
when you only think about the well being of others, you can never be offended
-MY MOM
I fucking love you...Quote:

Remember my frist grow log? That's a prime example of what a noobie can do with CFL's.. amazing stuff. :D
Happy 420 Folks!! I'll keep inputting my CFL info as much as i can.. and this thread is where it'll be.
I was thinking about next grow putting CFLs on the floor to light the bottoms of plants and keep the HPS for the top 1/3.
Would that cause a power overload and potential fire hazard if it was all on the same power strip? I'm no expert on electricity. It would be in an older apartment, built probably in the 1950s.
Thanks.
If you are looking for pics on cfl grow mobay could help you out there garden . Thanks bob very intresting can you tell me are they more expensive electricity wise or do they use less than a hps watt per watt.thank.The Postman.
i saw in your posted threads you had a few regular bulbs in the mix, if they're useless then why have them is there any effect that's benificial

I personally believe through trial and error that incandescent can be used as supplimental light for the source that you are already using (ie.CFL's). Most of my information is through direct reading from Ed Rosenthal and Mel Frank's "Guide to growing Marijuana" and trial and error. I've completed a number of reasonably successful grows... and currently working on my next with already great results.
As you can see.. my sensi star white widow is turning into a big girl.
These pics were taken just now.
Very nice muh man
First of all: NICE GROW! I've been considering doing a CFL and Waterfarm grow as an experiment to see what happens.
I have some questions about CFL growing. Namely, do you use SOG or just let the plant grow on its own? Also, what your grams per watt yield? I'm getting about .33 g/W yield with my 400W HPS. Meh.
krusty, that's what I just did and the buds grew wonderfully.
I use the SUPERCROPPING method.
another thing about those 125 watt compact flo's
they are great for new clones!
you can get the lights really close!
I am super impressed. I spent alotta mula on bulbs and ballasts and reflectors when all i needed were a few sockets with some cheap bulbs.
read your top 2 grows and i am closing in. On my 2nd day of flower.:dance:
Here are some pics
with a before and after of an LST session. also having some fun with a plant that had problems and is now on recovery, but i still dont expect much.
buy lighting.com has cfls up to 85w.= to 350wts
not much I can add...I am enjoying this. ON the retail tip:
lowe's sells 7pak of 14/42w cfls for 10 bucks...now that is a small lamps, but equal to almost 300 watts...
the point is; I buy these for my whole house.
thanks Bob. Looks like alot of info. lw
Great pictures guys!
Glad to see others have good results with these CFL's.
I'd like to point out that this lighting is ideal for "Noob" grows.. If you have the knowledge,money and space to get HPS or MH , then by all means.. do. your results will be tenfold.
But.. for those who can't do the 1000watt MH in every room of your house... CFL's are handy.
I'm going on about 3 weeks to harvest
...here are a couple pics.
I wanted to say that I have used them a few times for veg and they grow extremely nice under 4 of these 45w cfl's
I have so many experiments going that I use them as mobile utility/fill lights.
Here is an idea I had awhile back and I was thinking of blackjack when I saw this...utility light string...it is one of those multi receptacle light-strings for parties and construction sites...they are not that expensive, and you could string them all over a room.
I will find out which distributor has them, but I think it might be Zandor's favorite...Harbor freight...Great supplier for the small closet grower.
And finally, I agree with BB! These lights are great for newb grower's because they will not burn up your plants or your pocket book.
dont forget the 4 foot shoplights are also cheap and can be overdriven by 4x.
www.1000bulbs.com has some pretty good stuff
nice grow lets see that yeild
hello bob bong , i have been keeping up with your thread and i wanted to wait til i got my 4 in 1 cfl hood reflector. iam using 4/ 125w cfl cool bulbs now on my plants, i will veg for 1 week and throw the reds in. this hook has light hitting every part of the plants. my grow box is 3x4 and the reflector has 6 inches around the box for movement , perfect fit.
cheap too run good crop of them have a look www.envirolite.com
Great info folks, much appreciation for taking part in this open discussion.
On another note, i'm getting close to my first harvest and will be flushing within a few weeks. :thumbsup:
Enjoy
Bob.:stoned:
