How to clone cannabis
So, you’re ready to start cloning cannabis. The first thing you’ll want to do is gather the necessary supplies for success.
Typically made out of plastic and affordable, a cloner allows you to root your clones. They come in various shapes and sizes, and also tend to include a supply of growing medium.
You’ll need scissors to perform the initial cutting procedure with your mother plant and trim off excess water leaves.
This will help you keep your cuttings properly trimmed.
Rooting hormones help your clones develop roots faster and more consistently.
- Nutrient-rich growing medium
The growing medium you need will depend on both the plant you’re cloning and the type of cloner you’re working with, but popular options include rockwool or Rapid rooters. Most growers also keep perlite or vermiculite on hand, which help with drainage.
Unlike seedlings, clones require a higher humidity to thrive, so investing in a humidity dome is a great way to ensure your clones’ roots stay moist and healthy.
Because cannabis clones need to eat too.
As soon as you’ve collected all of your necessary cloning ingredients, you’re ready to start making your way through the steps of how to clone marijuana.
Step One: Prep the Plant
The first step is by far the most important: picking your mother plant. Remember, your clones will share identical genetics to their mama, so make sure you pick a cultivar that is strong and sturdy in the vegetative stage, and capable of producing a ton of beautiful buds.
Once you’ve made your selection, it’s time to cut. Select a branch that’s around six inches long and carefully use your scissors, ensuring the top bud remains intact. Cut your branches at approximately a 45-degree angle, hitting right below the third node and removing any leaves growing near the bottom of your cutting.
Follow up by immediately submerging your cuttings in clean water. This will help them stay hydrated until you’re ready to root.
Bonus Tip for Success:
Experts agree that the best cuttings come from plants that haven’t been fertilized in a few days, because the nitrogen will have worked its way out of the leaves. Excessive nitrogen in cuttings might trick your clones into growing vegetation rather than rooting, which you definitely don’t want.
Step Two: Root the Plant
After you’ve cut your clones, it’s time to root. Dip the cut ends of your branches in your rooting hormone as soon as possible, and then place them in your cloner and allow them to settle into the rooting medium.
If you’re using a humidity dome, now’s the time to cover your clones with it–for around 48 hours, which will help prevent them from drying out. After about 48 hours, crack or slightly lift the dome to let in some limited airflow. Plants need to breathe too. For the best results, keep your clones at 60-65 percent humidity for 7-10 days at 70-75 degrees Fahrenheit.
Step Three: Feed, Water, and Wait
The next step is simple and identical to how you’d treat any other cannabis plant. Feed, water, and wait.
Keep your plants well-lit, and make sure your rooting medium is neither dried out nor overwatered. Within a few weeks, you’ll start to see some new root growth, which is a prime indicator that you’re ready to move on to step four.
Step Four: Time to Transplant
Transplanting your clones can be accomplished by filling some pots with a potting medium, digging a small hole, and burying in one clone per pot. Make sure any gaps or empty space are filled in with soil, and water the plant thoroughly to get rid of any air bubbles.
Cloning Weed FAQ
How do I transition (harden off) a clone?
Slowly lower the relative humidity until you reach the average humidity of your growing environment.
How can I transition my cannabis clone to outdoors?
After adjusting your clone’s environment to local humidity levels, the plant can be placed outdoors in a well-shaded location, ideally protected from excess wind. Over the next week, your clone will build up a resistance to the UV radiation from the sun–sort of like how humans tan.
What temperature should I keep clones?
While rooting, it’s best to keep your clones at 70-75 degrees Fahrenheit (20-23 degrees Celsius) with a relative humidity or RH of 60-65 percent.
How do I know my clones are ready to transplant?
White roots will begin to appear at the bottom of the rooting medium, signaling that your cutting is now a plant and is ready for life on its own.
How much does it cost to clone cannabis?
Cloning cannabis can be done for anywhere between 10 cents and four dollars per stem, depending on how sophisticated you want to get.
What should I feed my clones?
If you have a very healthy mother plant, you won’t have to worry too much about feeding, because your clone will be packed with its mother’s nutrients. But if you need to, you can always supplement with sterile liquid fertilizer. Low doses of Hydroponic nutrients tend to work best.
