I'm going to transplant the indoor grow plants this week. The roots are peaking out of the bottom of the cups already. I've given them a tiny bit of fish fertilizer in their last watering and will be giving them a heavier dose when i transplant them. Between that and the mycorrhizae in the soil, I'm not expecting much if any transplant shock.
Update: went ahead and repotted the indoor grow. Gave them a heavy feeding of the fish emulsion.
