A plant only uses light of a certain type. The light that isn't used by plants is eliminated by some scientists and the measure of plant-usable light is referred to in other ways. The term "Plant Growth Lumens" is discussed on this page:

"What we aquatic plant growers need is a true plant-growth lumen (PGL). Here is how to calculate one."

This may be what you've seen with a different name. Photon light is another partially correct name.

Let us know what that word is.

Good luck to you!

"All light intensities on this page are in photons per second (Einsteins), not watts, as the activity of chlorophyll depends on the number of photons absorbed, not their energy."

Hahahaha, I love it when they talk dirty.

I started my quest at home depot as well. Dont buy anything from there! If you did, take it back! I got a very nice 175w Metal Halide rather inexpensively. Find a local hydroponics store, if there isnt one around, they are all over the net, just google for it. If you need to know what to get, these guys will tell ya, they have helped me mucho!

I started out just like you, and i am telling you dont make some of the mistakes i made, do it right the first time....i am now paying for a mistake i made because i didnt do it right the first time!

Greeny!
