i dont care that much about the money, if the bulb dies in a year ill replace it. The the biggest deal in the world. But the dual spectrum during flowering should increase yield. Even though the bulb would be putting out less lumens the plants could use more of it because its blue and red spectrum. Besides the cost of the thing, any other info on this?
I might consider ceramic metal halide actually since thats been proven....
thanks for all input, any more info preferably a grow report with a dual arc or cmh bulb would be freakin awesome
