This is my first try at this. No nutes at all, basic soil, tap water up until the most recent watering, going with distilled for the remainder. I put 2.5' black 90* pvc intakes to keep light out and carbon filters on the bottom of the lid (we will see how well they work). The plastic material that blocks off most of the heat turned out great, a square piece I cut to size, cut a slit and slid into the side of the bucket. All four sides have a gap inside to maintain airflow while blocking the unwanted heat.
