Is it possible? If you were to run a very tight SoG setup, taking clones and flowering them straight away. 48 Plants per sqm, Aeroponics and a 1000W HPS over 2 sqm. So basically each sqm would have 500W and 48 plants which means each plant would have to yield 20.8 grams every two months. It doesn't seem that impossible to me, the only 'questionable' thing is 48 plants in 1sqm, but remember they're clones and flowered straight away and you can cut away any pretruiding leaves so you're only growing the top/main kola. Each plant would have 14.5cm x 14.5cm (5.7 inches x 5.7 inches) Let's also, for arguments sake, pretend that we have perfect genetics, perfect growing methods, and taking large clones. Or am I living in dream world?
