'Cloning' is Plant Propagation from Cuttings:
Hortus IBA Water Soluble Salts and Rhizopon AA rooting products are used.

"Cloning" is just to take the cutting of a plant and grow it on it's own; roots will form and the new life of a 'clone' begins. This is no different from any other plant propagation from cuttings.

Propagation from cuttings is not a mystery.

Every year MANY MILLIONS of plants are propagated from cuttings. The science using rooting hormones has been around since the 1930's. Whether you buy a chrysanthemum plant, or a rose bush, there is a good chance that it was propagated using a Rhizopon AA rooting product or Hortus IBA Water Soluble Salts rooting solutions. In Europe the only supplier of IBA rooting products is Rhizopon, headquartered in the Netherlands. Rhizopon AA rooting products available in the US are the same as those in Europe.

"Cloning" is "Plant Propagation from Cuttings".

Class 101: How to Get Clones from Your Cannabis Plants .. and more.

Makers of costly 'Clonal Rooting' products (especially those associated with legal cannabis propagation) are locked into one way of doing propagation. They lead uneducated growers to believe their crop is 'special'. There are few 'special' crops that require unique materials to use in propagation. These products are costly because people 'think' they are better. YOU DON'T NEED A CLONING 'MACHINE'! (The makers give fake advertising .. costing you un-necessary money.)

Professional growers who produce crops in the millions a year have better experience then those who only propagate a few hundred or thousand plants. Rely upon the methods and products that have many years of effacy to propagate plants from cuttings. Rhizopon AA rooting products and Hortus IBA Water Soluble Salts, and their methods, have proven to produce superior roots on cuttings and are cost effective.

"Clonal propagation" of 'medical' and 'recreational' cannabis crops

The following information is suitable for the clonal propagation from cuttings of appropriate varieties of regulated 'medical and recreational' cannabis crops. Propagation of cannabis is subject to local laws and regulation; the user/buyer assumes all responsibility for use.

Disclaimers: The information given is for informational purposes only and does not constitute an endorsement for cannabis propagation in other than legal ways. For additional disclaimers reference the product Warranty.

To trial the propagation of most herbaceous cuttings there are a few ways to go.

The rate depends upon variety.

The Dry Dip Method:
> Rhizopon AA #2 or #3
(the most popular dry dip rate used by European propagators is Rhizopon AA #2)

Total Immerse or Spray Drip Down:
> Hortus IBA Water Soluble Salts
@ 100-250 ppm IBA

One successful protocol (given by a Colorado grower)

Use cuttings from the current growing season.
Soak the basal end of the cuttings, about an inch, into a solution containing Hortus IBA Water Soluble Salts rooting solution @200ppm IBA, for about one hour.
Cut back a small amount of the basal tip.
Apply Rhizopon AA #2 or #3 by the Dry Dip Method.
Stick the cuttings
Use misting to maintain humidity as required and continue to maintain the crop.

How to make a Rooting GEL

When making a gel based solution, use one of many standard gel products from your horticultural supply. You can also use corn starch from the food market.
Using Hortus IBA Water Soluble Salts, mix in water to make a rooting solution at any concentration. Then, add the gel powder or corn starch powder to the rooting solution (warm solution temperature is best) until you get needed ‘gel peaks' or somewhat watery solution as needed.

The resultant 'concentration' is defined as ‘parts per volume’. The rooting 'gel' will be higher volume than the original water based rooting solution.

The corn starch approach is an INEXPENSIVE WAY to use Hortus IBA Water Soluble Salts rooting solutions to make gels in an INFINITE range of rates.
