[Upgraded] 9Pcs Tree Root Growing Box with Drain Holes, Half Transparent Plant Rooting Propagation Ball & Metal Core Twist Ties, for Fast Propagation Plants (Size M)

[Air layering technique] Marcotting is a method of asexual propagation of plants. Applying the air layering technique, this rooting box promotes faster initial rooting and produces shoots with a 2x growth rate. It also helps to absorb more nutrients while keeping the branches in place, increasing the plant's survival rate.. [Half Transparent Design] Our plant rooting propagation box is half black and half transparent, so you can directly observe the root situation inside, like growth rate, moisture, or dryness of the soil, without taking it apart, and also keep roots growing faster in a dark growing environment.. [Oval Shape & More Drain Holes] We improved the air layering propagation balls with an oval shape for wider space. Moreover, the rooting box has many holes for easy drainage to avoid water logging, so you will not have to worry about the root being immersed in water, leading to rotting and dying in the rainy season.. [Super Durable Material] These plant rooting balls are made of high quality polypropylene material, which is not damaging to the plant, not easily oxidized, and reusable for a long time. Our rooting boxes use plastic-coated metal core ties for fastening, with four reinforcement holes that can be twisted or disassembled with one hand and locked firmly and securely.. [Multi-purpose Root Propagation Ball] These plant root growing boxes are fit to branch sizes of 0.27""–0.37”, suitable for roses, fruit trees, climbing plants, and difficult-to-root plants such as magnolia and camellia. PACKAGING: 9pcs Air laying balls (size M) and 40pcs Twist ties.
