Nice bro - digging the Hanging Gardens of Babylon style

I do the same, only hanging plants in the corners of my tent. If you want an easier time, take a pot of the same size and a hole puncher and use the puncher to make holes. Then hang up by the holes and put your plant in that pot. If you cover over the drainage holes you could even have the hanging pot as a saucer.
Nice one. I feel sure that there's a lot of us horizontal growers who could grab a few extra gm/w by using 'empty' vertical space (without getting in the way of the light for the other plants)
