I've seen some top quality buds from led in pictures but not in real life (meaning I haven't ever seen led grow bud except in a glass case but I didn't check it out). I wouldn't mind trying out some leds, as Howard Hughes would say: "It's the wave of the future."
But until I see people pulling 20 ounces off 600 watts of leds on the regular or without costing over $2K, I'll probably continue to wait for the technology to improve more before blowing a wad on equipment that is obsolete in a year or two.
I haven't smoked led grown bud but I can't imagine getting anymore high than I do off sun grown, MH or HPS, and aesthetics really don't matter much to me. Now if it improves the terpene production, which I've read it does, then a small panel for the head smoke just might be up my alley, a cheaper route to obtain the finest smoke I can. Cheers
