0.63 isn't that bad, what were your results from? Sqft and plant size
Glad that cob kicked it up to 1.13, what type of system you running and in what size area?
That was towards that Yoda guy, I saw him on Cobbys thread talking mad crap about Qb saying they were no better than Mars panels.
0.63 is really bad considering that's worse than cheaper options like DE HPS, or CMH.
And it's also clearly below what modern (cheap) LED bulbs can do.
80 lm/w LED bulbs can already achieve 1 g/w with a good yield strain.
100 lm/w bulbs are extremely common these days, and Philips/Osram already have bulbs around 120 lm/w.
And I don't even have to pay 0.5€/watt for a 13watt 117lm/w Philips bulb.
Yoda is mostly right about Epistar/Epiled.
There are better options that are cheaper too, therefore it's irredeemably shit.
Those Mars panels are also unreliable, and warranty is slow/bad.
Somewhat less important, those fans in Mars panels are LOUD.
With their bigger panels being as loud as 60db.
