Blumat Blusoak Automatic Drip Irrigation Kit | Soaker Hose for 4x4 Raised Garden Bed, Greenhouse, Indoor or Outdoor, Flower Box | Great for Off Grid | Sustainable Gardening DIY Kit

This watering system is designed to be buried up to 1ft or laid on the dirt, and can be used with a gravity-feed from a reservoir. It works even in a grow tent, as long as only water is run and no nutes. However, the kit seems to be missing some necessary components for single beds, and the proprietary tubing doesn't work with off-brand elbow reducers, so users need to buy specialized elbows which are quite costly or use a fine-threaded screw. Some reviews mention that the watering system can be tricky to get right, causing plant death through either drought or over-watering. However, when set up correctly, it works great and keeps plants watered perfectly. **
