How to get huge, dense, sticky buds using CFLs - ONLY!

Hi everyone,

Rob Narley is the name and CFLs is my game! I am a huge CFL user, and I don't think I want to ever use anything else, at this point at least .

I'm so tired of the negative talk that CFLs get, such as "you can't get dense buds using CFLs," or "CFLs are for vegging and cloning, NOT flowering," blah, blah, blah. I'm here to dispel these myths, based on what I have learned in my 7 months of growing Cannabis.

Yes..I'm a newbie at growing weed! However, I take a scientific approach to everything and I push the limits to get the best results possible. I'm also a huge DIY'er.

That being said, here's my take on how to get huge, dense, sticky buds, using ONLY CFL lighting. Let's dive in...

----

1. Genetics


Before you know what genetics you're working with, don't expect to get huge, dense, sticky, buds using CFLs or any other lighting setup. Make sure the genetics you are growing produces those types of flowers, or else you're chasing your tail in vain.

Dont expect dense buds from a sativa plant with naturally-airy buds or a phenotype or strain that
grows stringy. Even if you buy a seed that touts to grow into the most compact, resin-dripping, largest flowers on the plant; you can't tell until you grow it out (properly), or get a clone from someone who got the results that you're looking for.

Genetics first, then......

2. Complete fertilizer solutions


Don't pump your plants full of nute-of-the-week marketing hype. Use as close to ONE type as possible.
I personally use Dyna-gro foliage pro for veg and bloom (sometimes--rarely), and I think my plants are greener and buds look better than many pumping silos full of synthetic crap into their plants, because Mr. Executive Salesman says YOUR plants NEED it. Don't overload your plants with hormones and so-called sweeteners, just to become a marketing statistic--paying obscene prices for FOODS you can buy at the nearest Walmart--dirt cheap. I always saw past the tactics when I started out, and I avoid them now.

For instance, the Bud Candy you're spending oodles of cash (or credit) on, can be replaced by good ole' un-sulphured molasses. Or, perhaps the expensive RO water and filters you spend money on, coupled with the expensive loads of CALMAG--can totally be replaced by using regular tap water and some epsom salts, depending on your municipal water quality. Then you can take those savings and upgrade your lighting or ventilation, and really hit your targets!

Do the research on this one and go with the most basic, professional formula you can find. And dial it in. That being said dial it in--DON'T over-feed your plants. Burn them too bad, and you may get little to no harvest at all. Go easy on the nutrients and learn the ropes using bagseed before spending money on expensive equipment, nutes and genetics! That's what I did and it's working well for me so far!

3. CFL intensity


If your CFL reflector has two-23 Watt, 6500K bulbs under it, and your plant is in anything larger than a small party cup, expect the worst! Your reflector should incorporate the amount of bulbs equal to the amount of lumens and watts that you want to shine upon your plants.

Seeing how the sun provides around 100,000 lumens per sq ft. on a sunny day, you want to get as close to that number as possible for best results. Or a decent amount of wattage per square feet; 50 w.s.f is a great start. For instance, my 300+ watt hoods give 20,000+ lumens for a 2-square foot area. That equals 10,000 lumens per sq ft; 150+ watts per square foot. As long as the temps stay within a nice range (70°-78°), the more light, the better.

-----

4. CFL coverage


Stop buying 20 or more 2,700K and 6,500K CFLs, and scattering them ad nauseam all around your HUGE plant that takes up 6 cubic feet, expecting "dense buds!"

Here's a CFL rule to remember: INTENSITY matters, NOT coverage.

Stop making reflectors with 2 to 4 feet in length, and spacing your lights miles apart from each other! Totally defeats the purpose for our intents and purposes. Let's not see you on here screaming, "I have a 1,200 watt CFL grow, but my buds came out airy and I only yielded 18 grams!" Concentrate your light ALL ON ONE SPOT!

So many growers found online, space their CFLs all around the plant; yeah, each bud might be getting it's own 40-watt light; but what does that give each bud...2,600 lumens?? Awful...always!

Remember the "as close to 100,000 lumens as possible rule?" Yep, that goes for EACH bud and leaf on your plant. The sun doesn't divide up into 40 small suns , so why should your lights shine on your plant that way, while expecting "sun-like" results? Blasphemy.

Here's a picture of a CFL hood with enough coverage to shine on a SMALL AREA of one or two plants, which is what you want when flowering for max gains. Or some variation thereof...

Here's an idea of how to place your bulbs:

Here are some examples of how NOT to space your bulbs/lighting:

And PLEASE don't get caught doing THIS:

5. Don't let HID the bandwagon jumpers deter you.


Laugh at anyone who suggests you stop using CFLs and buy a MH or HPS, when you simply ask for advice using CFLS.

For instance, I run a setup with 2-CFL hoods, ONLY. One is 334 watts, the other is 300. The total lumens for hood #1 is 22,000+. The hood is roughly 1-2" away from the plant's foliage and/or buds. So considering light diminishes at the square of the distance (measured in FEET), at an inch or two there is a negligible loss in lumens, with all other factors mentioned in this post being in place.

Most people go with a 600 or 1000-watt HPS for flowering, and scream "CFLs can't make dense buds..blah, blah." Now, remember, a 1,000 watt will need to be kept at least 2 feet away from the top of the plant/foliage, usually more. A 600 watt will need to be kept 18 inches to two feet or more away from plants, due to the intense amount of heat being generated, unless a cooltube is being used. And we all know a cooltube reduces the lumen output even further.

==> A 1000 watt HPS has 140,000 lumens at 1 foot away; 35,000 lumens at two feet away.....

==> A 600 watt HPS has 90,000 lumens one foot away; 22,500 lumens at two feet away.....

==> My 334 watt CFL hood has roughly 20,000 lumens at 1-2 inches away...

( Lumens + wattage) + proper placement = HUGE light intensity = Excellent buds! :weed:

Get my drift!!! Good....

6. Lower humidity (if possible)


No, lowering humidity won't help your buds get bigger or necessarily denser. It WILL affect your plants' transpiration, and arguably help with resin production. Transpiration occurs less during low humidity, since plants want to perserve their "water." Low humidity forces plants to create more resin to coat their leaves, to shade them from bright light and to prevent from drying out.

The naysayers yap about humidity higher than 30% in flower is a problem, and it must be 40%-50%. The thing is, low humidity isn't hurting your flowering plants, and if nothing else is helping you to prevent or minimize the risk of dreaded mold.

Besides, plants seem to be more sensitve to humidity during veg, from my experience, and low humidity during veg doesn't help them, and could slow them down.

If you want to possibly increase resin production and watch the trichomes stack up, try running at humidity levels
between 20 and 35%.

7. Use the correct spectrums


Too much red early in flowering can increase the amount of stretch a plant experiences (as well as giving too much P in the beginning of flowering). So when you introduce more space between nodes due to improper light spectrum you are messing up your chances of getting good light penetration, since your plant will grow in height and won't be as compact. Not only that, but tighter nodes = tighter buds. Extra space
between nodes can equal sparse buds.

Mix your spectrums, at least during the stretch, to include at least 1-blue for every 3-reds that you use.
Or even try 50/50. Mixing spectrum of light gives your plant(s) as close to the full spectrum of light that the sun provides, giving you the upper-hand in award-winning CFL flowers!

DON'T use this kind of red...

nope.jpg
Nor this type of blue:


not blue.jpg

These are what you need to correctly mix for max results:

Ok, I'm being a smart a$$ here. Lol. Moving on.....

8. Use CFLs in close enclosures only!


CFLs are pretty much crap without walls to reflect the light and concentrate it back to the plants as much
as possible. Planting in your large, neutral-colored dining area is killing your results; those lumens are all over the place--although they LOOK like they're on your plant--they aren't.

Mylar reflects up to 95% of light, hopefully back to your plant(s) where the light is actually needed. Get a grow tent or equip your walls with Mylar, and make sure your plants are as close to those walls to absorb the light as possible, or your CFLs are near worthless for huge, dense buds. And make sure there are no light leaks, which could be wasting your precious lumens on who-knows-what.

Don't put your plant(s) in THIS room:


not here.jpg


DO put your plant(s) in THIS room:


tent.jpg

9. Cool your lights


Lack of cooling is one HUGE reason to get airy fluff, even if you have everything else dialed in to the tee. Don't be a moron and assume that CFLs are too cool to produce heat that NEEDS be managed accordingly; they can and will throw your grow area well into the 100 degree F's if you aren't careful and attentive.

Have a fan built into your reflector or grow cab to pull light AWAY from your bulbs, otherwise you are creating hotspots under the lights that will seriously affect your flowers. Pull the heat up and out--through your exhaust
fan, and out of the cab/room.

Here's a picture of how you want to equip your hood or reflector with exhaust, if at all possible:

10. Train your plants for "even" light exposure!


LST, SCROG, and other methods can be used to train your plants. If you want huge, dense buds using CFLs
but don't train your plants, you're wasting time without establishing the fundamentals. Most CFL setups are using numerous single bulbs, not one big bulb spewing several hundred or even thousands of watts. That being said, CFLs are in use to save energy, thus they don't give off the extreme wattage to create light which can penetrate deeper into your canopy. So, you must "bend" your plants so the fan leaves and flowering sites (nodes) are exposed to intense light.

With your canopy resembling a wide, flat bush, instead of a Christmas tree shape, light hits a wider surface
area of your plant's leaves and bud sites, thus giving your plant more energy to make large, compact flowers. If you don't train your plants, you may get a nice, dense "cola" closest to the light, but the lower portion of the plant will have stringy crap-for-buds. Train your plant! This site has some great tutorials for learning LST, etc.

Hey bro, awesome to catch up with you here. True about the quality, intensity of light being what makes cfls thrive. I am into the fourth week of actual flowering of my first grow, and went with cfls as well. The fixtures you made and how you have them cooled is awesome.

The way you put the bulbs together creates such a intense and valuable light force, and having the ventilation keeps all the heat drawn off up and away from the plants.

I do need to get the temp down in my tent under 80 again, though running only 5 of the larger cfl bulbs means cutting one or more is taking away a good amount of watts/lumens.

I have the space available to move the tent, and line the walls of the closet where the tent currently is, and make use of the height space available that the closet has, which would mean I could put together a cfl fixture.
 
Hi mate could you give me some advise on my groom room any advice if good for me.
my set up:

plants are: 2 critical autos and 1 power Africa
tent size 4ft,4ft,5ft Mylar lined tent
lights: 1 300w duel spectrum cfl bulb 1 200w cfl blue spectrum (was duel but one half went)
nutrients: GHE Flora series using lucas formula i change nuts every week and a half
light cycle is 18/6
plants age: the criticals are into week 8 of flowering and the power africa has been veging for about 9 weeks
im using dwc set up for pots
to me the two auto dont look all that big but any advice would be great or is there anything you would change

here are some pics of the plants:

So, what's your opinion on the CFL AGRO dual bulbs that run 2100K and are good for both growth and bloom? I've used once for two grows and the buds came out so-so...not exactly fluffy but not exactly dense either...

Looks like you're going pretty heavy on the N there bro.
I noticed a couple burned leaf tips too.

I never had a problem using my cfl lights and i get colas the size of my forearm. Funny thing is one of the photos of the fixtures you say not to do it how my fixture is(don't have a photo of my fixture as of right now).

I've used cfls on all my grows. A total of 5 grows. I have to say I've been very happy. I've gotten excellent buds, and the light bill only goes up about 10 to 15 bucks. Rodnarley you are on the mark about genetics. If you start with junk you get junk. I'm thankful for all the real breeders out there who put their life and souls into the plants so guys like me can grow great meds. If you are on a fix income like me, cfls and good genetics is the way to go.SAM_0078.jpg

im using the nuts to the t with the lucas formula i change then every 2 weeks now so im not sure if thats why my buds are so airy or is it because i didn't lst them or some thing and the lights are about 3 inches from the tops that burn was when the autos just blow up and started to touch the light when i went on holiday for 2 days :)

Awesome setup you got bro!!
Put me in the small space cheap bastard club :eyesmoke:. So I will figure out how to make cfls work for me until temps allow for this cheap bastard back outdoors!;-)

ive always used hid.. except for clones and mothers i used cfl.. i never liked the idea of wires all over the place.. and also, big buds are nice.. but i like big dense buds... a big bud might be very airy and only weigh 15 grams i like big buds that are hard as a rock and weigh a ounce. regardless though, good luck and fantastic job to all those cfl users.. i use a 600 and the first page isnt correct.. i keep my bare bulb vert 600w 6 inches from some plants and up to 15 inches to others further away. no problems with anything.

OH MY ..... Your plants are really porny.... so hot...

Please i beg you, provide me with some more information about these hotties :D Strain, Wattage for the big buds?, time flowering vegging... god, thats hot


Also, to the threadstarter. I have a question!
If 100.000Lumens/Sqare feet is our goal... how come no one has ever used that? I mean.. it is close to impossible to achieve with todays bulbs. 100.000 lumens shining on a single plant would be 1. waste of energy 2. you would have to use liquid nitrogen to keep that plant and the whole house from burning down.

People are using about 4000 - 20 000 lumens per plant and they come out fine. 4000 was a guy i saw Scrogging in his servercase with 3 CFLs 23W.

Im just saying, i find it wierd because to me your numbers doesnt sound very realistic even though they might be correct. Also, the setup you say is correct seems really wrong. Im not a smartass and im a much newer grower then you but wouldnt the light be shining only onto the other bulbs and much would be lost? overheating the other bulbs instead of shining all of its light onto plant & Mylar.

Please, explain to me why that setup is best, as im currently trying to find a good setup to use :)

Also, i am going to use about 7000 lumes to flower my plant. People say that is enough, why do you say it isnt?
2x23w 2.500k and 3x23w 6.500k

I just want some additional reasoning as you're the first person claiming the lumens need to be this high. That i've seen atleast!


Btw TS, you got some fine ass budporn going on there aswell ;) Happy tokes to u

no need to be a dick.. i was just saying lol. i guess since that argument we had awhile ago, your still mad about it... how hard are the buds with cfl though?
I was half joking,half being a dick...lol.....I'm cool man,I forgot what the argument was about.....i think it was the ol' you like hid,I like cfls argument?..blah blah blah:).peace


In my opinion also its mainly genetics on how hard/dense buds are....I have been growing the same mexi-schwag seeds forever and some are dense...most are not.
