Boost your cuttings root growth in your hydroponics system. If you've never used a root tonic, you are warned, you won't go back. You've never seen such thick and fast root growth. Use cloning gel for the tips of your cuttings - the special hormones will help protect and boost root growth from the stem. Use starter soak instead of water to dip propagation cubes into, or water propagation plugs for the perfect nutrient blend to get cuttings started for hydroponic systems.
