I think you meant to say LED, I just noticed you said "LCD" lol. You may want to edit that.
Well, the problem with LED lights is they don't provide an array of colors like HPS do. But I bought a 50watt HighPower LED panel from HTG, only problem is my seedlings aren't starting yet, so I can't give any input yet (I will buy more panels once these are in soil). It is so hard to find anyone that has really given LED a chance, and most of the people that will slam an LED setup are the ones who haven't tried them. Not to mention, there are many different LED panels on the market, so results are going to vary for everyone. But for the reduced heat, less watts used, longer bulb life, in the end, there are Many benefits over an HPS setup. Be expected to pay more for an equivalent LED setup vs HPS, some companies are over-rating their panels, light the UFO light imho. If anyone has any real input from testing, please leave some input. It suxs looking for LED grows and finding none. Thanks!
