Will these CFLs do ?

Got 5 100w 6500k daylight CFL's , Will they do in a double cupboard for 2 plants vegging ?, all cupboard is mylard if that helps too

Thanks

Those are 23 actual watt lights and are good enough for veg but you'll need more light than that at 2700k for flowering

They will work.

Thanks guys and yeah im going to get some 2700k for flowering when time comes, What spectrum does the 2700ks need to be, Is it warm or something ?

Thanks

you are looking at the incandesent equivelent wattage, that number is not what you go by, you go by the actual wattage, im gonna educated guess 23w or 26w of actual watts each. For veg that will be ok, but as long as u can control temps more is always better, for flowering you will need to add lights for sure.

2700k is the spectrum. Read this and you'll understand it all alot better than if i tried to type it all out real fast. i didnt write this.
CFL Wattage

Now sometimes there can be a lot of confusion when it comes to power of the light due to poor labeling but we will do our best toclear all of that up. Normally light manufacturers that make CFL’s generally will put two numbers on the box your CFL comes in. One is Actual Wattage and one is the Incandescent Equal. As you can see here on this CFL the Actual Wattage is 23 Watts, and it’s Incandescent Equal is 100 Watt’s. You need to totally ignore the Incandescent Equal and pay attention only to the Actual Wattage of the Bulb.



Color Temperature

You might see a lot of different labels when shopping at the store for CFL’s. Label’s including Soft White, Warm White, Cool White, Bright White, Halogen White, Daylight White, Full Spectrum. And also label’s like 2700K, 3000K, 3500K, 4000K, 5000K, 6400K, and 6500K. These are all the color temperature of the light you are using. This is a measure of how warm or cool the light given off by a lamp appears, with warmer colors having a yellowish tinge and cooler colors being tinged with blue. What confuses some people is that the warmer a color is, the colder its color temperature is. (ex. Warm White = 2700K). Bulbs ranging in the 2700K-3000K spectrum are usually labeled Warm White or Soft White, bulbs ranging in the 3500K – 4000K spectrum are bright white or cool white, 5000K is labeled Full Spectrum, and finally 6400K – 6500K is labeled Daylight. You can grow an entire crop with CFL’s if you chose the right spectrum of bulb’s. For Vegetation you will want to use 6500K or 5000K, and when you flower you will want to switch to 2700K or 3000K . The reason being, throughout the year the plant’s outside receive more 6500K light because the day’s in summer are long and hot and as Autumn/Winter get’s closer the day get’s shorter, and gradually receives less 6500K light and more 2700K light as the plant flower’s. Do what you can to avoid bulbs within that 3500K – 4000K because they emit very little light that Is useful to your plant. Notice here the difference between the CT of these lamp’s



How to use CFL’s?

In order to efficiently use CFL’s to grow your MJ you will need to position the lights around 2 – 4 inches from the foliage of the plant. If you place the light too close, then your plant will have nothing to vertically stretch to and it will remain short and stocky. (Ex. My First Grow and FarmingToronto’s) Some people combat this by addingCFL’s to the side of foliage instead of on top of it. On the other hand if the light is too far away from the plant, the stem will suffer elongation (stretching), which will result in loose and fluffy bud’s.It is very important to note that when using CFL’s it’s a daily “battle” to have lights in the right spot. Many of us are in our grow areas at least once a day anyway, so to move your bulbs a bit really isn’t that big a deal. Also many people wonder is it better to have many low watt CFL’s or just a few high watt CFL’s. Both way’s are capable of provided you a good harvest but I suggest you chose the configuration that is easiest for you and your grow area.

Where can I get these CFL’s?

Many low wattage (23-42) CFL’s can be bought at locate retail giants , such as Wal-mart, Lowes, Home Depot, and just about any hardware store you can find. If you are looking to purchase higher wattage (42 – 200) CFL’s I would recommend ordering them online. http://www.1000bulbs.com/2-to-200-Watt-Compact-Fluorescent-Screw-In-Light-Bulbs/ has very good prices on CFL’s ranging from 2 – 200 Watt’s. http://www.buylighting.com/Non-Dimmable-Compact-Fluorescent-s/75.htm has a good selection ranging from 5 – 200 Watt’s in a wide range of spectrum’s. I have used both of these sites several times and I would recommend them to anyone that plan’s to grow with CFL’s.

Cheers for that So i guess il be getting some warm white 2700k bulbs when it comes to flowering, Would it help if i put in a 20 watt 2700k for veg too to add to the spectrum a bit as i have noticed a few people have ?
