Has anyone used a Lumigrow pro 325 or 650? They say that the 325 is comparable to a 1000 watt HPS and the 650 is comparable to 2 1000 watt HPS lights. Is this accurate?
That's not even close to accurate and that's one of the reasons I'm not a fan of lumigrow lights. Such claims are nothing but sales propaganda and even that is being generous.
Disclaimer: I still use HID and I'm NOT an LED expert. All of my LED knowledge is from other parties or research so I can't say from first hand experience one way or another. I also run a medical grow consulting business in SoCal.
