Karma this thread is about LED vs HPS so there is no arguing put up the numbers or shut up now if someone is claiming there 342 watt led is same thing as a 1000 watt hid then the numbers should speak for them selfs how many LED growers you know achieving 1.5 the magic number ??? i do not see to many... matter of fact i am seeing more in the range of .7 .8 tops for instance being truthful strain environment, play huge roll but
we need to see what averages are out there just because a few may hit some nice numbers we need to look at on average what people are hitting a green horn with a 1000 watt hid will achieve .5 plus
i know of growers that pull 30 oz from 600 watt HPS have you herd the same from LED
stop using the few miracle growers that may have had a decent yield and look at the whole picture
