would this type of CFL be okay?

If I use about 4-6 of these in a grow box that is 5 foot tall, 2 1/2 foot deep and wide. There will be a reflector on top so that any light that is shining away from the plant can have a chance to reflect towards it.

How many actual watts do those lights produce. When I grew with CFL'sI had 750 actual watts for three plants in 5 gal smart pots. Needless to say I had a shitload of CFLs, I'm currently growing in a tent with very similar dimensions using a 400 watt hps to flower.

All that shows is voltage and wattage.
What is the Kelvin rating?

Yes you can use those,I would get more of them if you can.the ones that say 2700 on them better for flowering and 5700 better for veg if i remember right its been awhile.your gonna whant the bulbs close to the plants like 2 inches or so.I would suggest reading up on it in the cfl section in the indoor growing part of this sight,theres alotta good grows there useing cfls you could pick up some good info there to help you along.

6500K for veg works best but 5700K is better than 2700K. Flowering does use the 2700K and they are as common as mice. Available everywhere. The 6500K is a lot harder to locate in stores it seems.

Looks like that is a 23W CFL I started a seedling under once once, left it for a while and it stretched quite a bit. With 4-6 and a proper setup (I didn't have a proper setup) that should work for you.<br><br>Many lower wattage bulbs will not list the light temperature but they will list what type of light they put out, usually. Refer to the chart below, you would want daylight bulbs for veg and warm bulbs for flowering Often times the bulbs will have some indication on them of warm/soft/daylight etc... I usually see it listed somewhere on the bulb usually after wattage but not always. E.X. 23W/D Means 23 Watts Daylight. Of course if you know the exact temperature that is best but if you don't you can estimate. Warm bulbs will give off a very orange light whereas cool/daylight give off more of a white/blue:

A photograph of various lamps illustrates the effect of color temperature differences. From left to right: Compact Fluorescent: General Electric, 13 W, 6,500 K; Incandescent: Sylvania 60 W Extra Soft White; Compact Fluorescent: Bright Effects, 15 W, 2,644 K; Compact Fluorescent: Sylvania, 14 W, 3,000 K​

Is it important to get as much info about the lights temperature? I thought as long as I was around 80 degrees, I was okay. I didn't have to worry a lot about where the heat was coming from

Light temperature refers to the temperature of the color of light not actual physical temperature as in hot or cold.

Could u elaborate a little bit? Thanks

I had a thread I was trying to find when I came across this one. It was asking about some low wattage CFL's I found in my parents garage. They actually worked better than I thought they would. I used three of them and surrounded the plant with them. This go around, I found some 40watt (150w replacement) Sylvania bulbs. They're 2700K, 2600 lumens. They were at Lowes for like 7 or 8 bucks I believe it was. They're about 3 inches from the plant. Still 3 of them surrounding the top sides, with a regular 4' tube fluorescent, with Sunlight spectrum bulbs over the top. I am very satisfied with the turnout I'm getting from that. I may use as much power as 1 descent HPS. I'm not really sure, but their easy to find, cheap, and easy to replace. I control the temp with a good fan, and the A/C. So those will work. I seriously suggest getting some of the ones I switched to though. You will double your harvest. I even found them at family Dollar for 5 bucks. lol You will need a couple of them though.

*Edit*
Oh yeah, I'm using the fixtures with clamps(Like found for reptiles in pet stores). That way I can easily move them to keep them close. You HAVE to keep them very close. As close a possible, without burning up your plant. The worse thing about it is, you have to do a little trimming to keep the leaves from touching the bulbs sometimes. That does help with light penetration though.

Sorry for the low quality pics, but a old flip phone, is my only way to take them as of right now. These were done under the low wattage CFL's. Nothing to do with the thread, and I don't know what it is, but the stuff on the bottom, is some of the best tasting smoke I've ever had. Really fruity, and a nice sativa type high.
