Plants need consistent and proper amounts of water, but this can be a challenge, especially when you go on vacation. The GelSpike Vacation Watering System, featuring custom-blended DriWater, takes the guesswork out of the equation. The unique, all-natural gel, made of 99.5% pure water, gradually breaks down when in contact with natural microorganisms in soil. As the gel slowly converts back into water, it percolates down through the root zone of the plant to deliver moisture at a consistent rate. The GelSpike Vacation Watering System is your solution to keeping your plants happy while you vacation. Attach the GelSpike bottle to the water-releasing spike and and your plant receives slow, steady moisture for 2-3 weeks. GelSpike Refill bottles available. 100% natural, nontoxic and biodegradable, the gel is not a polymer, but is comprised of pure water and 0.5% food grade ingredients commonly found in ice cream.
