Frequently Asked Questions

Q: What bottle sizes are compatible with these drip watering spikes?

A: These self-watering spikes are designed to fit standard plastic bottles with a neck opening of 28–30 mm in diameter. This includes most common water bottles, soda bottles, juice bottles, and pop bottles — no special equipment needed.

Q: How do I control how fast the water drips?

A: Each spike features a stepless (continuously variable) flow regulator. Simply twist the dial clockwise to slow the drip rate and counter-clockwise to increase it, so you can tailor the watering speed to each individual plant's needs.

Q: Can these spikes be used outdoors as well as indoors?

A: Yes! These adjustable drip irrigation spikes are equally suited for indoor potted plants and outdoor garden beds, balcony planters, and vegetable patches. They're a great hands-free solution whether you're home or away on vacation.

Q: How long will one bottle of water last in the spike?

A: Duration depends on your drip rate setting and bottle size. A standard 500 ml bottle set to a slow drip can last several days, while a 1.5 L bottle on a low setting can keep plants watered for up to a week or more — ideal for short holidays or busy work weeks.
