This week, my experiment was successful, I stopped watering my babies for 4 days(mind you I only give my plants 250ml of water daily), to keep the medium from drying out all I was doing was turning the medium, but the real test will be in the height of summer when 30 degrees is a norm, if my babies can survive heat stroke, my aim is to drive the roots as deep as possible, well from my experience height is achieved with root depth. So these 20lt better give me tall lushes plants
