They definitely do the job but they create a nice amount of heat for sure. I have had some good and bad grows with them I first started with mars the cheap price and all the YouTube videos I watched intrigued me years later I feel you get what you pay for when it comes to them, onlyonce came close to 1gpw in 3 years of use(mars) and that was with 3 DP auto mazar's in coco.

I hear ya. Im littl curious, because ive been able to pull at LEAST a gram a watt, which is insane.. running 8 plants right now under a reflector series 144 and a 96. Constantly rotating plants and position to give them all similar lighting. I havent yielded less than 2 zips per plant ( and that was 2 plants that were each stunted). Typically the yeild are between 2 1/2 to 3 1/2 zips per plant, although i did yield 4 oz off a sour livers and a white widow freebie mystery seed. ( none of my plants were over 12 to 14 inches tall.) With that being said, what types of techniques, nutes, strategies, tec do you use when growing?
