Barney's Purple Punch AUTO DWC

The plant roots are starting to expose themselves through the clay pellets. The roots are short, and white! I am working this week to slowly increase the nutrient levels to reach 500 PPM and watching the plants reaction. I added a humidifier this week as the outside air is 25F and the house heating season has started. I added an Aquarium heater to bring temps in D.W.C. back to 67F as it was dropping into the low 60's during nighttime setback temp/65F. The complications, never end................😁
