I agree that the marketing is total bullshi&* but in all fairness any plants I have vegged under them and transferred to HPS are fat, many bud sites and full of resin. The proof is in the pudding and the smoke. There are hundreds of completed growdd with LED now some very very successful, some terrible. Just like with HPS or any other lighting medium. You can have the sun on your door but if you cant balance out air and water its pointless.

As for Plasma lights only drawing half the wattage to generate the same equivalvent wattage? How much does a HPS pull from the ballast? When you know that figure and when you know the figure then we can have a discussion. Just because something is 500watt it does not mean it uses 500 watts power! that bit should be basic science for anyone playing with currents!

The less aggro we can give each other on here the better. I am simply relaying information I was given by a reputable source. Admitantly he is trying to sell my his Plasma lighting but if its good enough for Chelsea Football CLub, Liverpool, Man Utd, Fulham and twenty more to grow their grass? I think its good enough for my plants. The sun on earth! Yes its going to involve some experimentation and dialling in but if you watch your plants they tell you everything you need to know!
