I remove the netting, and put them in 16oz. solo cups, leaving the pellet about 1/2" proud of the potting soil. I top water along the sides very sparingly, and when they are few weeks old I move them to the larger pots. When the leaves are spreading outside the cups they have enough roots to transfer without the dirt falling apart, plants are about 4"s high. I may be up-potting early but I've seen some roots of plants left in the cups too long..
Once in the larger pots I bottom water, and when I know they have three or four days outside I top water. It seems they don't get the side roots that support the plant in the wind when just bottom watering. This could also be because I move them to a larger pot early...growth has been good...so I'm staying with that method..
