Many growers gently scrape or even split the bottom of the cutting so more “raw” insides get exposed. As you can see from the pictures below, the roots grow most easily from the parts of the stem that are raw, so scraping and splitting exposes more “insides,” which gives more surface areas for roots to grow out of and promotes faster rooting.
Now, there is a lot of great info in Ryan Riley’s Growing Elite Marijuana book. If you read the entire thing from front to back, even a totally experienced grower will learn something, and probably a whole lot of things. For a beginner, this book has literally everything you will need to know.
At it’s simplest, cloning basically means cutting off a piece of plant and sticking it in the ground! New roots grow out of the stem, and soon you have a new cannabis plant!
If you have an automatic cloner or humidity dome, this is when you would place the new clone inside.
Quick Video Overview of the Cannabis Cloning Process
When possible, take clones from vigorous growth tips from the lower half of your plant, as they have more rooting hormones than branches toward the top and will grow roots faster. However, clones taken from any part of the plant will work as long as they have a nice growth tip at the end..
But how do you know which plants are going to be good when you have to clone in the vegetative stage?
If you do plan to dip your cuttings, take your cuttings from the water and dip your newly scrapped cutting immediately into rooting hormone powder or gel to seal off air bubbles and give your cutting what it needs to start making roots. Some growers will use gel and then powder afterwards to get the best of both.
This book isn’t for you if you’re just looking to grow a tiny amount of buds to smoke a few times a year.
Cloning is one of the easiest and fastest ways for cannabis growers to make many new (and basically free) weed plants at once! Learn how to start cloning today!
Rooting hormone (
This functional and affordable machine is great for anyone looking to experiment with cloning. You can also make your own version of this with a 5-gallon bucket or something similar if you want to cut costs even further.
It’s important to note that in order for this cooling process to work, the ambient air temperature must be cooler than the temperature of the water. The TurboKlone is also available in models with 28, 96, and 144 clone sites, covering both small- and large-scale growers.
Humidity dome (
These cloners are great if you will be cloning routinely and want a product that doesn’t require much attention, so you can focus on other aspects of your garden.
There are multiple types of rooting cubes made from different material, each with its own benefits:
The plant cell culture can be preserved indefinitely. To start growing, just give it a different set of nutrients to encourage root development.
- Rockwool: Made by melting rock and spinning it into fine threads, this common material is sterile and very porous. Make sure it has good drainage because it sucks up water easily.
- Peat: These hold onto moisture and are organic and biodegradable, but they can have difficulty maintaining their structure.
- Foam: These cubes don’t get as waterlogged as rockwool and have no effect on pH levels.
This model is made for 20 clones, but OxyClone also offers versions with 40 and 80 clone sites for growers with bigger gardens.
Modern technology has made it easier than ever to clone cannabis. Here are some products to get you started using clones in your garden.
