I have Been researching for months now, I've always used 1k hps, they grow amazing bud, but replacing the bulbs, plus the heat, and the amount of electricity they eat up it has become kind of an issue for me running 3 of them!
so I've been very interested in using a cob set up, unfortunately I just don't get it amd wont be abke to build it! Im not good with anything like that, regardless of how many videos and threads I've been on and watched!
so I've been leaning towards the hlg600, it's about $750 built and shipped with a dimmer nob. would cover a 4x4 very well, runs great on electricity I could run 3 of them cheaper than running 2 hps! the heat wouldn't Be an issue at all compared to my hps, but I'm concerned about the density and trichome production that I will get with this light compared to my hps!
the lights would be a dedicated flower light, everything about the hlg seems almost perfect for me, I'm just very worried I will have to add some sup. light or deep reds just to get the ending product I want (basically what u get with hps) and that would cost more money and more cost to run, which would make it not worth it for me considering the price of everything!
