What it does

Screws onto standard soda bottles so you can water plants hands-free while you're away
Durable design with reinforced ring prevents cracking even when tightened firmly
Fits PCO1881 bottle threads so the spike stays secure and doesn't leak
Made on demand from the US, custom printed for your order

Your plants stay hydrated for days without daily watering. This spike screws onto any soda bottle filled with water, then you push it into soil. The bottle slowly releases water as the soil dries out.

The design uses a reinforced ring that resists cracking, even when you tighten it firmly. It threads onto standard soda bottle tops, the kind you use every day. No special bottles needed. Just fill, screw, and insert into your pot.

Perfect for gardens, patios, or indoor plants you want to forget about for a while. Made on demand and printed from the US.
