Mini Aqua Globes take all the worry and guesswork about keeping your small plants watered - they work automatically for up to three weeks. And with this convenient set of three globes, you can keep small plants, herb gardens, and even hanging plants perfectly watered without testing the soil and plants every day. Your plants will absorb water from the mini Aqua Globe as needed - when the soil is dry, it releases oxygen into the bulb, which then released the exact amount of water your plan needs. Aqua Globes are individual crafted and made of hand-blown glass, so each one of your multi-colored bulbs has a unique shape and look. Keep your small plants watered the simple way and add beauty to your plants with the mini Aqua Globes.
