Re: 200 watt cfls.....i need info really bad
For veg growth they should do just fine. but for budding you need to use a lower CRI around 2000 k,
but of course the HPS are best for flowering

Re: 200 watt cfls.....i need info really bad
OK....this is what I've seen and heard on CFLs....I did ALOT of looking and researching online for a grow freind of mine. Full sun spectrum CFL bulbs are 6500K, not 5000K. For flowering (and if you wish during veg. growth also) your CFL should be in the 2700 - 3000K range. Good luck......

Re: 200 watt cfls.....i need info really bad
The quality would depend on a lot of factors, strain, air circulation, lighting, growing medium, ferts, etc., just keep in mind that a well tended plant, even if grown from bag seed, will be MUCH better that the product the seeds came from. Take a look at my plant on the members photos, my first grow, bag seed. I used four 200W, 2800 lumen CFL's I picked up at Wally World for both veg, and flower cycles. Everything I learned to produce the fine crop of buds pictured came from the great folks, and FAQ's on this site. Search first, my save some time waiting for answers to your questions.

Re: 200 watt cfls.....i need info really bad
ok the words 'full spectrum' sound very appealing indeed. you instantly think the bulb must provide what the plant needs, and technically it does, BUT.....
full spectrum bulbs waste a huge amount of energy producing green and yellow light and only a small fraction is actually usable blue and red.
pay no attention to the words full spectrum in this instance =)
dual spec on the other hand is specifically designed to cover OUR needs
so basically a 5000k full spec bulb is next to useless unless your deliberatly willing to pay for electric to help stimulate the economy
if going cfl 2700k for flower 6500k for veg, if going flouro tubes then find bulbs like grolux dual spec.
if you have some personal need to go 'full spectrum' then do some research into ceramic metal halides (NOT metal halides). i think you will be pleasantly suprised, but make sure to buy sunblock because these can give you the same cancers the sun can

Re: 200 watt cfls.....i need info really bad
a small note. an increasing number of growers reccomend part of your lighting to be the 'other' spectrum. IE during veg add maybe 1 red cfl to 3 or 4 blue and in flower add a blue to 3 red.
i dont know the benefits of adding a red during veg but i do know that blue cfls give off some UV which is definatly beneficial to resins on the flowers =)

Im using 4 2700k 23w bulbs and 1 5000k light for veg... is the 5000k light even doing anything?

How many plants are you growing? If its only 1 or 2 plants you will be fine. I'm growing a single white widow under a 200 watt cfl and another 100 watt 5000 k bulb. As long as you can contain the light around your plants while keeping fresh air, the rest is down hill. HPS bulbs are great and so are MH bulbs, but they are hot and expensive. It's really up to you how you set up your environment around your plants.

Re: 200 watt cfls.....i need info really bad
Hi there. I only grow using CFL lighting and consistently get around a gram per watt of Dense,Sticky and Stinky buds. I use 10 23w 5000k bulbs for Veg and once they're in bloom I switch to 10 42w 2700k bulbs for flowering.i usually grow 3 nice healthy plants under them but could probably do 5 with no issues. Check out my pics. I get buds bigger than my hand and I'm a bigger guy. Lol

The bulbs are in a 14 gauge piece of sheet metal I bent at work.

Here is how I figured out how many CFLs to use. Remember that CFLs may be advertised 100 Watts, but the plant only uses 23 Watts of that. This is the draw from the socket, BTW. So use that figure when doing the math. The rest is visible light useful only to us bidpeds.
SO. In veg, you want 30 watts per square foot of closet/tent/cabinet space. I use a mix of Daylight and soft whites, heavy on the Daylights. I go with a dozen (nominal 100 Watters at 23 Watts actual) in a 2' x 4' closet. I clip/mount 6 bulbs over the canopy and 6 bulbs down low to light up the lower branches and to provide penetration into the plant.
In Flower, you want 40 - 45 Watts per square foot, heavy on the soft whites. You can use larger wattage CFL's, if you can get them, or just use a whole lot of "100 watters". I mount them at different levels, too, wherever there is a shadow.
I Use socket doublers, some with reflectors and some without, whatever I have collected since I've been growing. But you can get a bathroom lighting strip and wire a round electric cord to it, and supplement with any arrangement you wish.
Now, for number of plants. It depends on how big they are. I work with 2' x 4' enclosures, so in flower, I only put 3 ladies in 3-1/2 gallon bins, to give the branches plenty of room to grow. In veg, the juveniles will be smaller, as will their pots, so I can place them closer together until they are ready to be up-potted and put to flower.
To keep the heat down, I put the veg on a different shift than the flower. Both are on 12/12, except for a 1 hour on time in the middle of the "night" for veg. The veg schedule is called the Gaslight Schedule, and saves you a chunk of change on your electric bill.
*sigh * so much to think about! As you can infer, I use passive ventilation, with lots of fans to direct airflow in and out of the grow room. Mustn't forget the fans if you're going to give your ladies adequate lighting.

Brother I get at least .7 grams per watt with CFL lights and I've done as well as 1.2 grams per watt at my best. So I'm gonna keep doing what I do. HIS add a Lotta heat too.
