If choosing between cxb3590 and the chilled pucks I'd go for the pucks. They can be used full cycle no problem.
And quite a lot of us have this rob333 on ignore. While hps is cheaper and can do a great job, he try-hards to bash decent led companies. He is also wrong when he states things like leds can't produce more weight or quality. It's like he ignores data and facts to push his own agenda. You can in fact cover a 5x9 with 2 x1000w hps or 3x 600w hps. Or 3x 630w cmh lights. HiD lighting has its place, but it isn't the end all of this hobby.
@rob333 Why is it so hard to have a concise post or edit your previous posts? Do you just like seeing an entire page with your name all over it?
