So the sun's lumens on an altitude of 0 is around 130 watts per square foot. I wonder if you were on a (3 miles tall) mouuntain if the output might be closer to 140-150 watts per square foot.
Lowered temperature when you get higher up, unless you were near the tropics or near the equator... ANyways... That's another thought another time.
Now what if you took four helium balloons and used them as boyeus to hold up a 12x12 lightweight platform, where you would have 40, equilibrium 3-gallon grow-bags lined up
You raised this platform ~miles into the sky (I'm thinking 15, but I smirk at this as that's really high up there when I think about it)
as to reduce the distance in-between your plants and the sun, theoretically increasing wattage per square foot
Something like this
