Thumbs down CFL lights ?'s
http://cgi.ebay.com/15ft-Lamp-Cord-W...QQcmdZViewItem

I am looking to buy 2 of these cords and use 2 27 watt 6500k daylight spectrum and then switch to 2700k for flowering and grow 2 plants in my closet.

just wondering if that cord will work for that type of CFL bulbs?

Use both spectrums at the same time.


DUAL SPECTRUM
With CFLs, you need the DUAL SPECTRUM, red and blue spectrums. That does not refer to the color of the bulb that you see. It refers to the kind of rays, like UVA or UVB, or the color temp of the bulb, called kelvins.
CFLS come in 2700 kevins, 3000, 4100, 5100, and 6500.

Low Kelvin bulbs, like the 2700k is for BLOOM OR FLOWERING, 6500k is for the VEG Spectrum. The others are "MID" spectrums or in between.
IF you use the MID-range bulbs (4100) then also use the 6500 and 2700s for a balanced spectrum.
In outdoors, the sun produces different rays in the spring (VEG Rays called Blue) and late summer rays for the Bloom spectrum, the RED spectrum. The sun also produces green, and orange rays, but plants do not use them.



Color rating - Measured in Kelvin (K). The higher the number, the more bluish the light. 4000K-7000K is mostly on the blue side of the spectrum for Vegging or GROWING, while 3000K and under goes from a white spectrum, to a redder spectrum and is best for BLOOMING or FLOWERING.
There is NOT one CFL bulb for both spectrums, two different kelvin bulbs are needed.


I have come to believe that 2 42 watt bulbs, in one Clamp Reflector is the most efficient, cost effective way to provide light to your Grow.
You also need one of these

and two of these




Available in black or cream colored at Walmart, Lowes, Home Depot and any Hardware store, about $1.69 to $1.99.
They are used to put two 42 watt CFLS in one Reflector.

I also like these:



1 to 4 Sockets Adapter A4E27


This adapter will allow 4 bulbs to be installed in one socket. Each socket on the adapter can support up to 250W, so it support up to 1000W in total.


I have seen these lined up and used in a Surge Protector:


Or try two of these :


in one of these:



One in each side. There is a socket on the bottom of this that u can not see.


One of those equals 3 sockets all 90 degrees apart.
