Been working on another way to cool water without having to continually change out 10 frozen water bottles every 3 hours. Ran a coil through a mini refrigerator freezer and put wet cloths and ziplock bags of water over the coils to transfer heat from the coils into the icebox to send back cold water mainly at night times when the AC is off in the shed. Keeps water at a consistent 72-75° range while shed temperatures are 5-7° higher. Saved me tons of time changing water bottles

Nutrient levels at 600-700 ppm

All 4 buckets (all connected plumbing) have been cooled from a starting average of 79° to below 70° for plant water. Plant water is being cycled through a cooler filled with water and frozen water bottles. This method works effectively, though you will need to change water bottles regularly to keep water cold.

Flora products. All as they are labeled on the bottle to use.
