First Time Hydroponics

Last week of vegetation. Switching to 12/12 lighting schedule tomorrow. No reappearance of mold. No more humidifier as the humidity is sitting at 40% with just the plants and buckets. Temp reduced from 75 to 70. One of my mainlined connections broke..... hit it with my water pump when changing water - taped it up and none the worse. These plants are so hardy when they reach the mid to late veg stage.
