Hello all. How long does it take for a system to be mature enough to support fruiting plants? I have a bed with soil, which should support plants right off the bat, and a hydroton one, but neither is producing fruit. Some of the plants are doing well, while others are meek, but while I get tons of flowers, no fruit. I have been using a small brush to hand pollinate the eggplant, pepper and cucumber, but nothing yet.

I can't imagine that the soil side would have any nutrient deficiencies since the soil could support the plants without the AP water. Could insufficient light, or excess nitrogen be the issue?
