Sub-Irrigated Planter (SIP) Continious Irrigation Block

thingiverse

Create a self-watering flower pot using a 2-liter soda bottle by cutting it in half at about 4 inches from the bottom, flipping the top over and placing it into the base. Alternatively, stack two 5-gallon buckets for a larger SIP. For multiple SIP connections, use the T-Block with a 1/4" OD container irrigation water line. Drill a hole in your SIP base, apply silicone sealant between the T Block and SIP base, and secure it with the plastic nut while curing. The parametric design allows you to change the size of the container for attachment; 4.5 inches for soda bottle SIPs, and 10 inches for 5-gallon bucket SIPs.
