I have several HLG 650Rs–which I loved immediately–bought this summer, but the newest model, the HLG Scorpion Diablo is SO MUCH COOLER that I think I’m going to eventually replace all of the 650Rs.
The difference is HUGE. You couldn’t lay your hand on the 650R for very long, but with the Scorpion Diablo, you can lay your hand on it ALL DAY.
The heat and humidity profile in my space improved dramatically. The plants are dripping with bud. (Currently Cement Shoes and Wifi)
