Oasis Origins Turbo-Wedge Cloning Strips allow you to refill and reuse the divided carrier tray from the Turbo-Wedge Kit. The wedge shape of the growing media is proven to enhance the growth of roots for more robust plants by focusing root growth downward. The unique tray design keeps the roots from entangling with one another, making transplanting less stressful to the clones. Oasis Origins also provides a sanitary rooting environment, allowing clones to grow healthy and resilient.
