Strawberry Cough AUTO DWC

This will be the last week of Vegetation I believe, roots are healthy, I am changing the water every 5 days rather then waiting 7 days Had issues where the nutrient water became "jelly like" with a layer of it everywhere. I avoid by changing water more frequently. Now for the Water cooler in the picture, I got a plan... Homemade Nutrient water chiller It's an old Black&dekker bottom loading water cooler. The pump that brings water to the top still works and the valves are working, More importanly the refrigeration unit is working still, I am just waiting for a temperature controller to come in and I should have a Picture by Picture walk through to get it done.
