Jack Herer in a Pc - stealth micro-grow

This is great, looks like some silica going on there maybe. I came to you via Easy Growers mini grow diary. I've got to ask as you are using coco i wondered if you end up watering the whole container in the early stages to get decent run off? I imagine the roots take a while to go to the far left and right edges of the container.'d be interested to know thanks.
