I think the information Kamel presents here is quite revolutionary. It totally changes my prespective on indoor grows. Couldnt imagine messing with venting and electircal wiring (though its not that complex just not practical in my situation). This changes everything though. Not only does he point people to original references but then summarizes so the rest of us can use the knowledge - extraordinary. If theres ever a reason to max out someones rep this is it.

Sorry to gush, so heres my question. How do grow shops justify prices such as those below? The equivalent 3 x 65W Lights of Am would cost around $35 (Im assuming that 200W is the true wattage). Would the expensive lights last longer or be of higher quality for better yields? The break even would be about 5 weeks.

Thanks.
