I think its funny when people tell me I can't grow much with a dual PC fixture. I remember when PCs were the new leds you know. They used them for how long with no issues now I need to trash them and spend $300 on leds. When it comes to any hobby generally if you can afford the new technology you already have it. When I say I'm using PCs why tell me to trash them if I could afford leds I would have them lol. some people irritate the crap out of me.... sorry for the rant that's what I get for using another forum lol
