Thirty-six is too much for a Mini-M, in my opinion.
It's doable with a ton of CO2, but with razor-thin margins for error.
I'd recommend twenty-seven watts. If you can find a non-screw-in/non-quad-tube type fixture, that'd be best.
UG does not need all that much light and carpets as a part of it's nature and not in relation to light intensity, like Glosso.
So wattage is not really the priority so much as CO2 levels and flow. (UG likes flow, I've found.)
