well, yes, it IS a competition of sorts ... when you claim LED is the way to go, you should demonstrate with photos, just how well they grow plants, as compared to HPS ... I am EAGER to make a switch to LED, just like I switched to high-pressure lamps a few years ago ... but, I didn't spend the big bucks to switch, until I saw how effective they were ... some of us are still waiting to see the improvement, that's all ... money talks, us poor people have to see results, before investing ... Merry Prankster, I checked out your Grow Log, and you have a real nice, little plant there ... it appears to be identical, to plants I grew for many years, under fluorescent tubes, so I can't say there's any improvement there, $$ - investment-wise ... but, as I said earlier, I'm still rooting for LEDs, they will be the wave of the future (just not yet) ... :smokin:
