Rainwater upgrade: We only turned over this rain barrel yesterday, set bottom up for winter to keep empty in order to avoid frozen water expansion cracking the plastic, and it rained overnight. A little rain, a fair-sized collection area (roof with eavestrough), the law of gravity, and presto, the first seedling water of the season from just outside the door, a lot handier than having to haul it over in 50 lb jugs from the well pump in the barn, a bit of a hike away. Modern conveniences!
