Ok. That will work as long as you finish them sm & aren't trying for those 3'-4' plants. I'm growing sog & hope to finish at around 2' (I think in metric, 3' is around a meter). SOG, or sea of green. My favorite method for sm spaces. Hardest part about a lot of plants in a sm space is air flow. Gets co2 to the plants, keeps down insects & disease. Your plants are SO pretty, just keep in mind they get wider too!
