Blumat Watering Stakes - 16 Plant Self Watering System - Made in Austria - Great for Houseplants MADE IN AUSTRIA with the highest grade ceramic materials. Includes 16 Blumat Juniors for Potted or Hanging Plants. GENUINE BLUMAT  Watering stakes connect universally to nearly all plastic water bottles. Attach to a full plastic water bottle. Then, poke a hole in the top of the bottle (allowing water to release), and stick the Blumat near your plant's base. Its that simple. LONGER LASTING than knock-offs. On average, a Blumat stake with a 1L bottle will last 5-7 days, as compared to other stakes that last 2-3 days. The secret lies in the specific porosity of our ceramicsee for yourself! BETTER THAN THE OTHERS  Weve tried terracotta wine bottle stakes, ceramic stakes, and glass globes. They over water, make a mess, and ultimately kill your plants. So stick with the original, Austrian engineered, Blumat Plant Watering Stake. 100% MONEY BACK GUARANTEE  If you arent happy with your Blumat Garden Spikes, which is rare, you can send them back for a full refund, no questions asked.
