Cannabis Cloning: The Complete Guide to Endless Cannabis

Wouldn't it be awesome to grow awesome cannabis, without having to buy seeds after every harvest?

Cannabis cloning does just that.​

When you grow a plant, every single cell of that plant contains all the biological information necessary to reconstruct the whole plant.

This means that if you have a strain of marijuana you’re happy with, and you want to replicate your strain time and time again, your current females can become mother plants for clones.

What is Cannabis Cloning?

Cloning refers to creating identical copies of your plants.

You do so by cutting off a part of your plant, that when planted properly and rooted in a different place, will grow roots and become an exact replica of the mother plant it came from.

A cloned plant looks and smokes the same as its host plant and produces the same effects.

When correctly cloned, the same host plant can be replicated an infinite number of times.

The science behind cloning isn’t that complicated, but if not done correctly, diligently and in the proper conditions, cloning can be a complete failure, and the process can become spoiled, or the result will not be a satisfying plant.

Benefits of Cloning

There are several benefits that cloning presents as opposed to starting again from seed.

While starting a new grow from seed allows you to grow several new kinds of strains, here is how cloning can be a good option for the grower:

  • Faster Harvests

Cloning your cannabis takes a few of the stages of cannabis growth out of the equation.

When you clone, you’ve already done the work of germination, bringing the seed to the seedling stage, and have gone through the necessary steps to get your plant to its vegetation stage.

Cloning involves taking from an already grown plant, while it's still in the vegetation stage, and allowing that piece of the plant to grow roots to become a full plant within itself.

  • Money Savings

Cloning your plant eradicates the need to purchase seeds.

If you have a strong enough strain that is successfully producing plants, anything to do with seeds gets taken out of your growing equation.

  • No Questions About Sex

If you don’t know what gender your plants are when you start with seeds, you’ll know that there’s a little guesswork involved.

When you clone, you will already know that your mother plant is indeed a female that has produced buds.

Any clones taken from that mother plant are guaranteed to be female plants that produce smokeable bud.

More Advanced Techniques

Cannabis cloning has become a lot more sophisticated, and there are highly scientific methods that have been applied to clothing.

Micropropagation or “tissue culture” is a horticultural process that involves growing plants in test tubes (“in vitro” in a way) from single cells found in a plant.

Micropropagation is a process that is not too easy to achieve by home growers, due to the need to have these procedures performed in a sterilized laboratory.

Since the plant cells can be so volatile through this process, cloning through this method is very specific and precise.

Thus, cloning via severing parts of the plant become the most common method for growers to clone within their homes, and this will be what we’ll focus on today.

Conditions for Cloning

If you’ve decided you’ll want to clone your cannabis plant at home, conditions for your plant are everything.

Here are a few things you’ll want to make sure of before attempting to clone your plants:

  • Timing.

To be successful in your cloning, you’ll want to ensure that your host plant is in the vegetation stage.

Ideally, one that has been in that stage for a while (i.e. two-month minimum).

You can clone up to a few weeks before harvest.

But the deeper into the flowering stage that you get into, the more chance your clone will take on strange growing characteristics.

  • Sex.

While we mentioned this before, you’ll want to ensure that you’re cloning from a female plant, and that your clone is not grown from feminized seeds.

Feminized cannabis has a tendency to spit out hermaphroditic clones​.

  • Nitrogen.

Some cloning resources will recommend decreasing the supply of nitrogen to the plant by 10%.

This can help with rooting once you have clipped off the branches.

  • The Length of the Branch.

The branches that you clip off will want to be 6-8 inches in length to be productive clones.

It’s also best to clip these off the bottom of your plant which will promote faster rooting.

However, you can consider cutting from the top for faster flowering from the new plant.

  • The Grower.

This means YOU.

To clone successfully, you need to embrace your role as both a plant surgeon and plant scientist.

You should understand the complexity of cloning and how any little deviation from the process can result in the failure of your clone.

You’ll also need to be patient and not expect to see instant results.

Although you will be pleased with how quicker cloning is for getting to bud than planting seeds.

What You’ll Need to Clone Cannabis

There are a lot of resources online that will teach you how to do cloning using some very precise tools, but we’ll start off as simple as possible for now.

Here’s what you’ll need for your cloning process:

  • Very sharp scissors or a razor (sharp is key!)
  • A sterilization solution such as alcohol
  • Sterile gloves (i.e. latex or Nitrile)
  • Starter cubes that you’ll place your clones in (i.e. with rock wool, soil or water, depending on how you’ve been growing)
  • Cloning gel or powder
  • Your desired lighting (or sunlight for outdoor growers)
  • Heating mat (optional)

A Step by Step Guide to Cloning Marijuana

Clean, Sterilize and Sanitize

Cleanliness is key to starting off your cloning process.

Wipe down all your instruments with alcohol (99%) soaked into a paper towel.

Ensure you have gloves on throughout the process, as well as, all the processes associated with your cloning.

Prepare Your Cloning Gel or Solution

Your cloning gel or solution will be what helps your clone take root and flower.

They use synthetic root hormones that allow you to see your plant to root within days.

Do your research when checking out cloning gels and solutions. provides a very helpful overview of some of the cannabis cloning gels and solutions available on the market on their YouTube channel.

This video may help you narrow down what to look for when shopping for cloning solutions and gels:

Prepare your solution or gel according to the instructions on the box and get ready to move onto the next step.

Get Starter Cubes Ready

Whatever method you’re using to plant your clone, be sure that you have soaked them in water so that your clone will have a refreshing drink once it gets planted within the starter cube.

Depending on whether you’ve used a heating mat, you’ll also want to put this in place to create the growing environment for your clone.

Make the Cut

Now is where you’ll want to approach your plant and the cutting process with a surgeon’s precision.

As mentioned, it’s always best to take your cuttings from the lower part of your plant.

This part will have had the longest time growing.

Meaning it’ll have more nutrients helping the clone take hold in the rooting process and grow.

Cut the stem of the branch at a 45° angle, while ensuring that your branch is long enough as specified above.

If you use scissors, be sure that they are sharp.

You don't want to squeeze the plant while you’re cutting with scissors.

Many prefer to use a razor to help with this precision.

Some choose to split the bottom of the cut stem with a razor as well to help the rooting process.

If you do this, don’t go too deep.

Here’s when you have to think like a surgeon again:

Make sure that once you’ve split your plant, you place your stem in water immediately.

Like the veins in humans, getting air into the veins can be deadly.

Pro tip: Cut the the leaves in half going parrelel with the base of the leaf. This allows the clone to transpire less.

Clean Up Your Cut

Once you’ve done your cut, while keeping it in the water to avoid air bubbles and to keep the nutrients focused towards rooting and growing, trim the excess leaves off your cut towards the bottom.

Do The Dip

This is where you’ll want to be as quick as possible and eliminate any distractions.

Once you’ve done the trim, quickly take your clone from the water and dip it into your prepared cloning gel or solution.

Leave it there for about 15 seconds so that it can suck up everything the solution has to offer.

Don’t waste any time – you’ll still want to get it into where it’ll be rooting right away it to prevent air bubbles.

Plant It

Once your stem has been sufficiently submerged into your cloning gel or solution, gently place it into its starter cube.

Whether you’re using rock wool, soil or water, be sure not to plunge your plant into the cube too forcefully, risking damaging the clone.

Let the Roots Take Hold

Now that you’ve taken great care to clone your cannabis plants in a sterile environment using the precision of a plant surgeon, step back and let your roots take hold.

Of course, you’ll want to maintain watering your clones as you did when you were growing your host plant, but for the most part, if you’ve done the above steps correctly, nature will take hold.


As a grower, you’ll already be familiar with transplanting your plant to a different pot; the process to transplant your new clone is very similar.

Once your plant has rooted and needs to go to a larger pot, you’ll want to take extra care not to expose your plant’s new roots to the air to risk damage.

Be sure that there are drainage holes in your plants pot for watering.

Before transplanting, be sure that your plant has a layer of soil to be placed in and then gently pack the soil around the roots of your plant.

Nurture Your Plants Towards Flowering

Now that your plant has gained roots in a growing environment that allows it enough space to flourish, you can continue nurturing your plant towards flowering.

Use the same methods you have used with your original plant.

Or test different ways to perfect the strain.​

You’ll still have to wait several weeks to get to the flowering process.

General Guidelines to Remember

If you’ve been able to see flowering occur in your cloned cannabis plant, Congratulations, you just successfully made a marijuana clone.

Let’s review some of the components that led to a successful process:

  • Cloning from a healthy and strong mother plant
  • Ensuring you’re working in a sterile cloning environment
  • Cutting the clone from the mother plant during the vegetation stage
  • Ensuring no air bubbles get into the cut stem
  • Using cloning solution or gel
  • Carefully planting the stem into new rock wool, soil or water
  • Ensuring the plant is transplanted to a new pot at an appropriate time

Do Your Research

This is a very simple overview of the cloning process.

It can’t be overstated that the grower who's interested in cloning should do their research before attempting cloning.

The resource above gives a general guideline, but the growers community is becoming increasingly sophisticated in the way they’re cloning plants, and they’re eager to share.

Sometimes cloning doesn’t always go as planned.

Learn from those attempts to understand what went wrong with the plant, the process or within the environment and try again.

Once you get the process of cloning down, clone that, and you’ll be on your way to a sustainable supply of your favorite strain that will never disappoint.
