manufacturer by 10,000. For example, a product with 0.9% IBA contains 9000 ppm IBA.
    An all-natural, root-inducing substance is willow (tree) water. The substance in all willow trees that promotes rooting is unknown, but repeated experiments have proven willow water promotes about 20 percent more roots than plain water. This willow water is mixed with commercial rooting hormones for phenomenal results.
    To make willow water rooting compound, find any willow tree and remove some of this year’s branches that are about one and a half inches in diameter. Remove the leaves, and cut the branches into one-inch lengths. Place one-inch willow sticks on end, so a lot of them fit in a water glass or quart jar. Fill the jar with water, and let it soak for 24 hours. After soaking, pour off the willow water, and use it for rooting hormone. Soak the marijuana clones in the willow water for 24 hours, then plant in rooting medium. If using a commercial liquid rooting hormone, substitute the willow water in place of regular water in the mix.

Cloning gels are very popular because they keep root-inducing hormones evenly distributed along the subterranean stem.

Get all cloning supplies ready before starting.
    Canna products and several other commercial products contain Trichoderma bacteria. The bacterium causes roots to grow and absorb nutrients better. To learn more about it, check out the Canna web site www.canna.com .

Grow More Roots

Split the stem of clones to expose more of the cambium layer just under the “skin” of the stem. It is the only place that generates new roots.
    Exposing the cambium layer causes many roots to grow there. Lightly scraping away the outer layer of the stem to expose only the cambium allows hormones to concentrate where roots start. Splitting the clones’ stem exposes more surface area to grow roots. Both practices increase the number of healthy roots, but rooting time is a few days longer.
    After the cutting has been trimmed and scraped, dip the bare stem into a rooting hormone. Now it is ready to “stick” into the substrate.

Split the stem to initiate more surface area for roots to grow.

Avoid problems:
    Keep the work area clean. Wash work surfaces and tools before starting.
    Have grow medium ready.
    Prepare mother plant (scion).
    Take clones.
    Store unused clone.
    Insert (stick) cutting in growing medium or aeroponics system.
    Place clones under humidity tent.
    Look for root growth.
    Transplant when roots emerge from root cube or medium.
    Harden-off by gradually exposing to new environment.

Before Making Clones
    Making clones or cuttings is the most efficient and productive means of cannabis propagation for small growers, both indoors and out. Once females have been distinguished, you are ready to practice the simple, productive art and science of cloning.
    Disinfect all tools and working surfaces to kill bacteria, fungi, viruses, and other diseases already present. Use sharp scissors, razor, or razor blade dipped in alcohol, vinegar, or bleach (five to ten percent solution). Wash your hands thoroughly beforehand.
    Make sure to have all cloning supplies within arm’s reach–rooting cubes, hormone, razor or scissors, humidity dome, etc.–before you start to take clones.

Cloning: Step-by-Step
    Step One: Choose a mother plant that is at least two months old. Some varieties give great clones even when pumped up with hydroponics and fertilizer. If a variety is difficult to clone, leach the soil with two gallons of water for each gallon of soil every morning for a week before taking clones. Drainage must be good. Or mist leaves heavily with plain water every morning. Both practices help wash out nitrogen. Do not add fertilizer.
    Step Two: With a sharp blade, make a 45-degree cut across firm, healthy 0.125-0.25-inch-wide (3-6 mm) branches, two to four inches (3-5 cm) in length. Take care not to
