DWC Res Change

DWC Res change in Veg and in Flower. The nutes in my DWC reservoirs gets changed every 7 days. We top off a plant finishing in flower and feed our Coco plant. Using the Technaflora line. Important tips: Keep your nutes inside your res under 70 deg Fahrenheit. That includes the res change with new nutrients. Keep PH pens calibrated, and have the drops around just in case they can save your ass! Keep your shit clean! Clean buckets, floors etc. Insulate your DWC buckets. This helps, I was able to handle the summer heat a lot better than last year.
