the light i mentioned is only $42 i think....screw it into a base and you are set...2 of them and you will do great in a little box:thumbsup:

if you adress the spectrums needed like LED's do they are actually easier to grow with because you are giving the plant light it can use!

Lumens and Lux are measurements of how bright a light source appears to the human eye. Since the human eye is most sensitive to colors plants don't need, and least sensitive to colors plants prefer, Lumens can't be used to accurately compare the plant growing capability of led grow lights.
If a grow light manufacturer rates his grow light output in Lumens they are only telling you how bright it will appear to you and light your room, not how well it will grow your plants. The most accurate unit of measurement for comparing plant lighting is the micro Einstein, which measures how many photons of light strike an area per second.

But, while this is a much better way to estimate a lamp's plant growing ability than Lumens or Lux, it is still very difficult to directly compare two different types of grow lights. All grow lights except the LEDs grow lights emit large amounts of light plants don't use very efficiently, so including that light output in a light's plant growing measurement is misleading.

hope this explains it better!:thumbsup:
stra8outtaWeed Reviewed by stra8outtaWeed on . Leanin toward 70W Hps.. Need a push Hey guys, been a devoted reader for a while, mainly in the cab section, but i decided to register :jointsmile: Only reason i stuck to CFLs was to accommodate for heat, but like the title says, i think i can get away with a 70W Hps in my new box. Just usin good bagseed > Taprooted in warm napkin > planted in plastic jello shot cups filled with perlite and poked with holes. i think i can ScrOG 2 plants very low, but do yall think i could get away with this bulb? I dont like readin too much when Rating: 5
