The Lechuza Maxi Cubi Self-Watering Planter offers a hassle-free and ultra-stylish way to grown flowers and plants. This lightweight, polypropylene planter is shatterproof and UV-resistant and comes in a variety of colors. But it"s what"s inside that really counts. A signature water reservoir and wicking system keeps your plants watered for up to 12 weeks. Water is drawn to the plants roots - where it"s needed most - and an easy-to-read water level indicator lets you know when it"s time to refill. This planter includes an ample supply of PON for proper aeration and plant nutrients. How the Lechuza Self-Watering System Works This modern, cube-inspired planter uses a self-watering, sub-irrigation system to nourish your plant. The included separator piece forms a reservoir in the base of the removable planter liner. A supply shaft with water level indicator runs along the inside edge of the liner, making it easy to add water and liquid fertilizer while maintaining complete watering control. A layer of LECHUZA-PON granulate drainage material lies on top of the separator and regulates the amount of water your plant receives - no more rotten roots! After potting your plant with soil on top of the pon drainage material, you will need to water the plant from above through the soil for the first 12 weeks. Each time you water, fill up the supply shaft, too, and don"t forget to add liquid fertilizer every other watering. After that, the plant roots will have grown deep enough to soak up water from the reservoir below. All you have to do is refill the water supply shaft when the level indicator reaches the "Min" position. At this point, your plant will be entirely self-sufficient for 1-12 weeks, depending on the size of your planter and plant. If using outdoors, remove drainage plug from base to release excess rain water while still maintaining reservoir supply.
