Going on vacation and can't find someone to look over your plants This water timer and pump combo unit pumps water from a bucket to water up to 10 plants or flowers. It is ideal for watering indoor or outdoor plants on your patio or balcony where a faucet might be unavailable. Minimize the risk of over watering by programming the timer for how long and often plants are watered. Save yourself time from hand watering and automatically water your plants with the Melnor Water Timer and Pump Watering Kit.
