Vividaire 18 oz Self-Watering Plant Globes 4-Pack — Glass Bulbs with Terracotta Stakes for 1–2 Week Automatic Watering

Vividaire 18 oz self-watering globes are glass watering bulbs with terracotta stakes that automatically feed plants for up to 1–2 weeks per fill.

These Vividaire watering globes pair a roomy 18-ounce reservoir with a porous clay stake to deliver a steady supply of moisture directly to potting soil. Designed for houseplants, hanging baskets and small outdoor pots, the system relies on capillary action and slow water release to reduce overwatering and keep roots consistently hydrated while you travel or manage a busy schedule.

How long will a single fill keep my plants watered?

One 18 oz refill typically maintains adequate soil moisture for most small to medium pots for about 7 to 14 days, depending on plant type, pot size and ambient temperature. Warmer, drier rooms shorten that window, while cool, shaded spaces extend it.

• Average indoor use: 1–2 weeks per fill
• Smaller pots or thirstier varieties: refill more often
• Avoid direct hot sun which accelerates evaporation
• Use more than one globe for larger containers or groupings

Will the terracotta stake prevent overwatering or root rot?

The porous clay stake meters water slowly into the soil rather than dumping it all at once, promoting balanced moisture levels and reducing surface runoff. It helps maintain a steady soil dampness ideal for many common houseplants, but you should still monitor drainage and potting mix to avoid saturation in non-draining containers.

• Clay stake releases moisture gradually via capillary action
• Works best with well-draining potting mixes
• Not a substitute for proper drainage or root health checks
• Remove for inspection if soil stays soggy or plant shows distress

How do I set up and use these self-watering bulbs?

Setup is simple: fill the glass globe with water, insert the narrow end of the terracotta stake into the globe, and press the clay tip a few inches into potting soil. The unit operates without electricity or special tools; refill the globe when the water level runs low.

• Handwash glass and stake before first use
• Fill globe, attach clay spike, insert into soil
• Place away from intense afternoon sun for longevity
• Top off reservoir as water level drops

Can I use these globes outdoors or with different plant types?

Yes — the globes are suitable for many indoor and sheltered outdoor plants, including foliage, flowering pots and hanging baskets. Avoid exposing the glass and clay to prolonged harsh outdoor conditions like freezing temperatures or constant direct sun to preserve their lifespan.

• Good for indoor houseplants and protected patios
• Suitable for flowering and foliage varieties
• Not recommended for fully exposed, harsh outdoor environments
• Use multiple globes for larger containers or thirsty plants

Who is this for: Vividaire 18 oz watering globes are ideal for plant owners who travel, busy professionals with limited time for daily care, and anyone who wants a low-effort way to keep potted plants consistently hydrated. They suit beginners seeking a simple automatic solution as well as experienced gardeners who want to reduce daily watering chores. For best results, pair the globes with appropriately sized pots, well-draining soil and occasional manual checks to ensure roots stay healthy.
