DoubleFill 24oz Terracotta Ollas Self-Watering Planter Inserts, 6-Pack — Porous Clay Keeps Plants Hydrated Up to 3 Weeks

DoubleFill terracotta watering pots are 24 oz clay self-watering inserts (6 per pack) that release water slowly to keep potted plants hydrated for up to three weeks.

These handcrafted-style clay ollas act as buried reservoirs that feed moisture directly to the root zone, reducing evaporation and overwatering while simplifying plant care at home, in the office, or on the patio. Each 700 ml globe uses porous ceramic to meter water into surrounding soil, making it a low-effort solution for people who travel, have busy schedules, or simply want healthier container plants with less daily attention.

How do these terracotta watering globes actually work?

The DoubleFill clay ollas rely on capillary action: water moves through the porous ceramic surface into dryer soil, creating a balanced moisture level around roots. As the soil dries, it draws more water from the reservoir until it reaches equilibrium, delivering a steady, slow trickle rather than sudden soaking.

• Porous terracotta releases water gradually via capillary action.
• Reservoir holds approximately 24 oz (700 ml) per globe for extended watering cycles.
• Bury near roots so moisture goes directly to the plant’s root zone.
• Works until soil moisture equals ceramic release rate; refill as needed.

Will one globe keep my plants watered while I'm away for weeks?

Yes—under typical indoor conditions one 24 oz globe can sustain many small to medium potted plants for up to three weeks, depending on plant water usage and environment. Larger or thirstier plants may need more than one globe or larger pots may require placement of two globes spaced apart.

• Lasts up to three weeks in moderate conditions for small/medium plants.
• Use two globes for large pots or high-water-use plants.
• Helpful for short trips, busy weeks, or irregular watering routines.
• Monitor and adjust frequency based on plant type and season.

How do I install, refill, and maintain the clay watering inserts?

Installation is straightforward: fill the globe, push it into the potting mix with the neck exposed, and check periodically. Refill by removing or pouring through the opening; cleaning requires gentle scrubbing to remove mineral buildup if hard water is used.

• Fill with water and bury near root ball, leaving the neck accessible.
• Refill through the top opening whenever the reservoir runs low.
• Clean occasionally with a soft brush to prevent mineral clogging.
• Handle carefully—clay is durable but can chip if dropped.

Can these terracotta ollas be used both indoors and outdoors?

Absolutely—DoubleFill watering pots are versatile for windowsill herbs, balcony planters, patio containers, and garden beds. They reduce surface evaporation outdoors and maintain consistent moisture indoors, making them suitable across many plant types and settings.

• Suitable for indoor potted plants, balcony planters, and outdoor containers.
• Works with vegetables, ornamentals, succulents (use cautiously), and houseplants.
• Helps reduce water waste and prevents runoff in outdoor pots.
• Not recommended for plants that require consistently dry soil unless carefully monitored.
