bro you must be pretty stoned how do you figure you save over cmh 630 w replaces a 1000 watt hps...
your yaking about apples pears and oranges u save very little electricity over cmh with led.. but you pay over 3 times the price 1000$ to buy it.. cmh got the full light spectrum that not bad with proper ventilation .. i just did 459 grams
my last grow.. more than i grew with a 1000 watter with more plants ..
now as for hydro bills i think my hot tub is laughing at the grow lights and saying turn up the nukes... 10,000 watts..
jan is scary but great time for a tub..
