I live in the Uk and have a specialised supplier here I have been using for LEDS for the last couple of years. His new products have the LEd built into them RED/BLUe and then full spectrum white light. The most powerful model is 500watt but only draws 250 and is about 20 times brighter than a HPS 600watt. There are few suppliers around but i think in the states Lumatek is leading the way and there are a few grow logs around on other sites showing these in action.

I will be doing a Plasma log as I should have done with the two I am doing at the moment with an LED/HPS split. (all vegged in LED though) Four weeks away from finishing on 55 Armageddon that look stonking, and 2-3 weeks away on 100+ Lowryders, The AK48 looking ridiculous and certainly no lowryder!

I have spent all and everything on this setup so cant afford a new camera at the moment, hence no grow log. There are grainy photos on another link.

cheers
mrnobody Reviewed by mrnobody on . Drowning in conflicting plant graphs - help! (LED) Still trying to design my LED light through clear understanding and not just mimicking. There is one photosynthetic response curve that shows yellow light has more effect than blue light and that green, while lower, is almost as useful. Other articles say green light may stunt plant growth and that yellow is not much more useful (despite the huge success of HPS). Then there is the photosynthesis action spectrum showing that violet/purple light (400nm) has the highest absorption peak Rating: 5
