My first ever successful clone
This was without any rooting hormone whatsoever. It also was rooted outdoors under a semi included greenhouse with no dome! Skip to “How Come I’ve Never Heard Of This Before?” for more info.
Is it necessary to add Root Growth Hormone when cutting your clones?
FIRST it should be noted that this advice may not apply to all species. Some root less readily than others.
You should consider trying the free and savvy method only on a small portion of any size-able crop before risking your entire investment on a new method.
Also, for this to work you must NOT tug on the shoot to test it, ever! Even after a couple of weeks a dying plant has been known to do the “Phoenix” and rise from the ashes once again. My first attempt rooted in about a week and a half un-covered and outdoors in moderate fall weather (the plant in the very first picture of this article).
You do not need root growth hormone to successfully clone plant cuttings as the plant already has the hormones in the leaf tips. When all conditions are met, the cutting will grow root and establish itself. Using human saliva will not make the process faster, but it along with especially the chewing action may encourage better or more root growth. It seems to definitely help speed up the process as well as keep the cuttings healthier during the process. Read on and try it for yourself!

How Come I've Never Heard Of This Before?
For some reason it’s simply assumed that cannabis needs rooting hormone in order to successfully take cuttings — and this is another common case of a falsehood commonly accepted as fact.
I first heard about this tech from my roommate who was in a pinch one year after accidentally killing the bulk of his crop. Using intuition from previous grows he concluded that the plant should be able to regenerate without rooting hormone, so he simply took cuttings and chewed the very ends of their stem to the point where the fiber started to break into separate strands, but not enough to mush it up. He then stuck them in small, uncovered planters (I think he said plastic cups w/ drain holes) and left them uncovered.
These were not his plants and he urgently needed a solution to his caretaking mistake. When the owner returned, the quote I remember hearing was:
“What the fuck did you do?”
All of the cuttings had started to perk back up towards the light the yellow de-faded to green — to everyone’s amazement!
This really comes down to species, since many plants will root if they happen to flop over and have any contact between the soil and their trunk or even other stems. Ficus have even been known to do “air-rooting” where they grow roots through dry air off of their trunks towards the soil.

proven Documentation of the effects of "auxins" on roots
“Pioneer studies in the 19th – early 20th century leading to the discovery of auxin are introduced first. In 1928, Dutch botanist Fritz W. Went finally isolated auxin diffused out from the tip of oat coleoptiles in the gelatin block. Following Went’s success, auxin, indole-3-acetic acid (IAA) was then isolated first from human urine, then from fungi, and finally from higher plants. Discovery of auxin is thus the result of the work of many botanists and organic chemists from various countries. Biosynthesis, metabolism and physiological actions of auxin are also briefly described.”
It’s our understanding of plant auxins that allows us to clone plants so easily via different propagation methods today. One may duplicate a very similar or exact match of a mix of plants for a very long period of time. Different propgaation methods may include budding and grafting depending on the species.
Money tree: Or The tree of many kinds
With cloning, you can have many plants similar, if not identical to the plant that you want to clone in a short space of time. Plant propogation helps makes production more realiable since you can expect similar results as the mother plant. Normally the genetics degrade somewhat over time, however — and it takes a skilled grower to stave this off past noticeable levels after 3-5 generations. It is for that reason that seeds or refdigerated cell cultures which can be regenerated later are preferred for long-term genetic preservation.
Fun fact: different species of fruit trees and vegetables have been proven able to be grafted into one single plant! This begs the question which other plants this may work with? See this video for an example of 40 citrus on one tree:
The Basics of Cloning a plant
the leaves store resereve hormones
For a plant to grow roots, you need the leaves to create food and to also stimulate rooting. When you propagate via cuttings, leaves become the main source of rooting co-factors and endogenous auxin. When you remove a cutting from the stock plant, too little leaves will slow down or stop leaf growth, while too many will create a burden to the plant and it will die. A study has shown the the optimal amount of leaves on a cutting are two or three to have a successful root growth. Three- leave cutting has better root quality due to more carbohydrates, while any more will cause stress to the cutting and no rooting success. The most important factors are ideal temperature, an adequate amount of leaves and enough sunlight. Growth hormones and human saliva are great helpers, but they don’t seem to be essential in with many species.
