Perhaps,LED Grow lights is more effective for the plants growth.

This is a thread about Plasma Lighting.

You'll also notice that one of the tested lamps is a Plasma/LED combo.
If you want to discuss LED lights, there is a thread which is similarly named under general growing.

So read through the thread and it goes back a couple years... so has any good progress been made in the plasma arena? It's been said that plasma would'nt be good for flowering on it's own...has that changed?

ive been watching this for a long time the spectrums avail for lep are right on the money for optimum growth.. lep/led both have made major strides in the past year.
eventually ill have one and from looks of things now maybe ill test it first here at cc. dank1. start with this small one.
