Adjustable Valve Watering Spikes - Set of 6

These watering spikes provide your plants with water evenly and slowly, even when you're not around – for up to 15 days. Each spike connects to a standard plastic bottle, which serves as a water reservoir. An integrated, adjustable valve regulates the drip rate from 0 to 60 seconds per drop, allowing you to precisely tailor the amount of water to each plant's needs.

Installation is completely tool-free. Simply prepare a suitable plastic bottle (bottle neck inner diameter approx. 28 mm), screw on the spike, invert the bottle, and insert the spike into the soil. Set the valve to your desired flow rate – the plant will be watered automatically as long as the bottle contains water. Water-soluble fertilizer can also be added to the bottle to combine watering and fertilizing.

The set includes 6 spikes in two color options – blue or green.
