Frequently Asked Questions
How do glass watering globes work?
Glass globes rely on gravity and soil moisture tension. Fill the globe with water, invert and insert the spike into moist soil. As the soil dries it draws small amounts of water out of the globe, giving plants a slow, steady supply over days.
Will globes or reservoirs overwater my plants?
Most passive systems release water only as soil dries, reducing overwatering risk. However, poor drainage or very compact soil can trap moisture. Choose inserts sized for the pot and ensure pots have drainage, or use planters with built-in overflow/drainage features.
Are glass globes suitable for outdoor use in summer heat?
Yes for sheltered outdoor spots, but direct midday sun and heat increase evaporation so refill intervals will be shorter. Also keep globes where they won’t be easily knocked over; glass is attractive but more fragile than reinforced plastic.
