While many veteran growers may scoff at the idea of using Compact Fluorescent Bulbs (CFL) to cultivate cannabis, Oaksterdam University reinforces the technique by having one of their official course books dedicated to the art of cultivating marijuana using CFL bulbs. The book, written by SeeMoreBuds, is titled Marijuana Buds for Less and carefully explains how to grow medical marijuana using only 6 42 watt CFL lights.
The lights, which should have reflectors attached, are used to germinate seeds in soil, on an 18/6 schedule and should be placed no more than 2 - 3 inches above the soil. As the plant grows, the bulbs should remain at all times around 3 inches from the plant. CFL lights do not give off nearly as much heat as HID lights are thus are able to be placed much closer to the plant, without burning it. This also reduces stretching of the plant, which will cause it to grow short and bushy, which is ideal for this method of growing. The 42 watt bulbs give off 2,700 lumens each, and are on 24 hours from just after the seedling stage to the flowering stage. When you wish to force flowering, simply switch the schedule to the normal 12/12 light cycle.
CFL lights are much cheaper to run than normal grow-lights, since they are designed to be energy efficient and for those who are especially concerned about the energy bill, you can grow one plant with as little as one CFL light. Enjoy this relatively new and inexpensive way to cultivate your medication.
So I was wrong all along.
It seems that CFLs can be used to harvest plants!!!!
You get what you pay for, and cfls are cheap. If your trying to raise some perfect plants I would suggest investing in more expensive lighting.
Now that I think about it I guess the fact that I'm willing to use them with expensive quality seeds in an new experiment says it all.
If ya care my two little baby girls just popped outta the rockwool and I'm already proud of them. If you wanna to know more info or even better if ya know how to nutrient and autoflower please let me know I'm basicly flying blind in that department!
Anyway if you would like more info or even better if you know how to nutrient a autoflower (that's most of my experiment,lol) feel free to drop me a line, peace.
@lindzzz: I used to do the whole process under CFL and was going to do that for this one to show others how, but it's fairly self-explanatory if you know the basics so I decided to finish under the 150 watt HPS light I have.
help , dont have a lot of money any ideas
Or go to Home improve store and get 65w (300w equivalent) with standard socket for $17-20
reg. 23w - 45w cfl for the house will disappoint you they don't have enough luminosity or ??? to grow dank but the others do
DID YOU KNOW THAT RAW (UNCOOKED) THC-A WILL NOT WILL NOT GET YOU AS HIGH AS COOKED (250`F FOR 5-10 MIN) WHEN EATEN IN CAPSULES) WOW WHAT A DIFFERENCE!
IF YOU HAVE SOME BLOSSOMS THAT DONT TERMINATE (STOP GROWING) JUST PINCH OFF THE SPROUTING BUDS AND YOU CAN RECOVER SOME LOOSE BUT RIPE BUDS IN JUST A FEW DAYS
I'm totally confused by this statement...
1x 9x10 bud room
1000 watts of CFL's bulbs all together.
18 HOURS 6500K CLF.in grow room
11 hours budding 1 2700k bulb to 4 6500k bulb ratio in bud room.
no dirt. (dirt tast better but it costs more and it's dirty;).
the trick is to put one (1) plant per week into the budding room.
Than in 10 weeks you take one Plant per week out.
PROS>you play god and never run out.
CONS>Bugs will kill everything.
if it's not medical, the cops will too.
PS, always us a carbon air filter.
Most people try to go CFL watt equivalent output to watts against HPS or MH but CFL's don't produce the same amount of lumen per watt output.
Example: a 23 watt/ 100 watt output CFL will produce 1600 lumen, so 10 of those will produce 16,000 lumen.
So you'll want at least 12 23 watt 100 output CFL's to replace a 1000 watt HPS unit.
I use 1400 watt units (i mix 2 or three 6500k color bulbs with 11-12 2700k bulbs) I bought from a local guy in Portland a few years ago. I was hella skeptical but man I gotta tell yea...I love the money I'm saving and my bud is WAY better than it was before under just HPS in flower...dense, crystallized high THC content DANK! He's got a website now at CFL-GrowLight.com and he's doing pretty well.
So anyhow.. I rather stupidly set up a grow box out of two rubbermaid tubs out of stuff lying around my house.
Its got a nice airflow, a carbon scrubber, and so far is very stealth. But I have yet to actually start growing cause of a few reasons.
1 - Its only 18 inches high.
2 - Its only 18 inches high.
The only storage boxes I had were 5 gallon tubs. So combined together they dont even make two feet tall. Which sort of sucks for me.
I have wired in the lights and chosen a pot. So now I'm down another 6 inches. So now I only have 14 inches to completely grow and flower. I plan on LST from an early age. But am not too sure how much that will help.
Also not sure what the strain is. One day a backpack appeared in the back of my truck. It had a jug with around 50 seeds and they have just been sitting around for a few years so I decided to give them a try.
I have a tendency to ramble.. sorry..
Anyhow.. What would be your approach to this situation?

Here's instructions on how to make it: http://www.tomorrowsgarden.net/content/cfl-grow-light-information
that are 1600 Lumens each. So 3 of these 8 bulb light fixtures would use 24 of these giving a total of 38400 Lumens using 550 Watts.
I plan to get the 80 bulbs for $80 (free shipping) because they are handy to have around, and I have enough sockets to use 56 bulbs (yea... 89600 lumens would be nice and under 1300W. Like I said, I plan to use 3 of them for 38400 Lumens):
These are also available in the 6000K rang but I lost the link. I will use LED, two T4 grow tubes, and a few 2700K CFLs for vegging.
A site for 105W 6,200 lumen bulbs that will fit a regular light socket for $28.29+ shipping is:
I have 6 plants in veg. stag. I have about 12 CFL's. Total ACTUAL wattage is about 350. Half are cool white (the blue spectrum) and half full-range (the yellow-red). Running 20 hours on and 4 off (I just think the plants should "sleep" for a few hours). The CFL bulbs are VERY close to the plants (4 to 6 inches) and it is all in a mylar tent. DO NOT USE ALUMINUM FOIL - mylar reflects back all light frequencies, aluminum absorbs some and can become hot (this is fine for a heat-sink, to wick heat away, but you need to reflect ALL frequencies and the heat back). Because of this moving the air around is a good idea, I use an old computer fan placed as low as possible (as the coolest air is at the floor).
Anyway, my plants are growing LIKE MAD. And it is flat growth. When flowering comes I will most likely switch to HPS. But for the veg. stage CFL's RULE!!! They are cheap and chep to operate. What's not to like?
