Advantage V. disadvantage CFL's

Stickyhits your wrong, you ever heard of cri rating? cfl's have a rating of 80 almost perfect sunlight on color spectrom & much cooler wont burn plants! hps rate at 20 very poor spectrum light, their extremely hot and must watch every day, no vacation or plants burn up! hps will make it grow faster possibly, but with poor quality unless other lighting is added to it

there is nothing wrong with cfl's HID's are great also i think using the right tool for the job at hand is the most important thing to rember.

I am using ( 4 ) 85 watt/350 watt, 6500k output CFLs. They are doing great. Ordered ( 4 ) 105 watt/ 450 watt, 2700k output for my bud "flowering" stage. Can hardly wait. 8 super bushy plants, white widow, kandahar, and big bud. Grow room is 4ft X 3ft X 10ft, Aeroponic-hydroponics, lights on for 24 hrs. If you like using CFL's, get them at Express Light Bulbs. They have what you need. I think CFL lights are the future in grow room Gonja.

System: Aeroponic, Hydroponics
1 solution tank, 2 GrowBoxes
( 4 ) 85watt/350watt, 6500k, 4200 lumens CFL Grow lights
Germinated White Widow, Kandahar, Big Bud
Was real impress with these CFLs I bought from Express Light Bulb, excellent choices for all types of grow lights including a large range of CFLs. They cost a little more, but the big ones are far superior than those small 42 wattage ones from Walmart.
Order my bloom lights today
( 4 ) 105watt/400watt, 2700k, 7100 lumens, be here by end of week
Starting bud season in couple weeks, we are going to have some fun

CFL's are great starters, I started with a 9W cabinet fluorescent tube, then graduated to (two) 23W CFLs and (one) 18W CFL so far I am pleased with the results and am 4.5 weeks into flowering. My next grow however will be HID since I want to get the best out of the time and energy expended to grow. I encourage all first timers to use CFL's.

Hey all! I'm brand new to these forums, and pretty new to growing. I just started my own medical grow and I have a question about the bulbs. I have 42 Watt CFLs with 150 watt equivalent. I have three of them on three sprouts in a 3x4x5 foot cubicle thingy. The problem I have been confronted with while reading these posts is that the box for my bulbs dont say "warm" or "soft" lighting, or anything like that. Also, the side of the box says 4100K and from the chart I found on here I think that means that they r worthless. Someone please tell me thats not the case!? Can I just replace one or two with different color spectrum bulbs? Any ideas would be helpful, I bought the damn things by the case...

how well would a cfl that was 5500k do for veggin?

Well sorry to be the barrer of bad news..... But having a bulb in the 6500K for veg would give you MUCH better growth IMO, than that 4100K. lol, sorry bud, and you want 2700K for flower.
6500K=veg
2700K=flower
Stick with that, use at least 100 ACTUAL watts per plant, and keep the lights within 3 inches of the plant and you'll be golden!

Do you have any grows on here? i am about a week into my first indoor grow with CFL's (first indoor grow period actually)
Id love some feedback as well
cfls are the future! i clone, veg and flower with cfls and have fantastic results. i get 4 to 6 plants over 2ft and ready for harvest in a stand alone closet in 2 1/2 months with just 1 125w red spec cfl. and my clones are at 99% rooting, while i run 24 hour veg also with NO problems, no need for extra ventalation nothing. if you growing under 15 medium sized plants stick with cfls!

Thanks for the tip man. I have a medical room and so I can only flower 6 plants at a time. I plan on switching to flower when they are about a foot tall, is that right? Do you have any tips on the best strains for indoor high yield?

i have no idea if the argument about light intensity ever finished or what, couldn't be bothered to read 62 pages of posts. but from what i understand from studying A level physics, if light waves are coherent, which they would be if they are of the same colour spectrum and wattage, then they are in phase. This allows them to reinforce at certain points, which in an experiment using slits, shows bright and dark fringes where light reinforces and superimposes.
So, surely this would mean that light intensity can fluctuate as a result of reinforcement and superimposition?
I'm probably wrong but this is my input.

i was just looking to see if there is any point in useing cfls . i know its cheaper but do they work good for flowering.
