How to Clone Marijuana: Step-by-Step Guide

If you want to increase your knowledge and understanding of growing cannabis strains, then cloning should be part of your arsenal. Cloning marijuana is a great and reliable way to harvest and yield without relying too much on seeds. The process also allows gardeners to produce buds without risk of affecting certain factors like potency.

Cloning does require a bit of experience in growing marijuana plants. You need to know which plants are most successful in delivering bountiful yields in certain growing locations. Furthermore, you need to know how to differentiate male buds from females. Once you know this information, you can properly start cloning cannabis strains.

What is Marijuana Cloning?

Before we start teaching you the ropes on how to clone marijuana plants, it’s never wrong to absorb more information about the subject matter at hand. Know that the theory of reproducing marijuana by cloning is relatively simple but the procedures may not be as foolproof for some interested gardeners.

Cloning is most successful when done outdoors but it’s not impossible to do it indoors. Even if you’re expecting a long growing season for your chosen strain, don’t expect your clones to reach their full potential, especially regarding their heights. Most clones won’t start growing until about 3 months into the growing season.

However, it doesn’t mean that thought is the same for all marijuana clones. Short cannabis strains grown by cloning can still end up with astounding yields. Even though the entire process is relatively risk-free, many cloned strains have smaller lifespans than their originals.

Choosing a Mother Plant

Now that you know a bit more about marijuana cloning, it’s time to get started with the procedure. Cloning starts by selecting a mother plant. During this step, it’s important to be patient. You need the original plant to be sturdy and it should also have a short flowering time. The mother plant should also produce great yields with large roots and strong buds.

If you’re reading this guide and it’s your first time cloning, then you may not have the right experience to know which plants are best to clone. Regardless of your choice, you should start by choosing female buds found in a relatively healthy state. Healthy female strains will have a higher chance of surviving the cloning process as compared to their male counterparts.

Furthermore, it’s best to choose mother plants coming from regular seeds instead of feminized seeds. Bear in mind feminized seeds come from stressed marijuana plants. If you stress those plants further then they become hermaphrodites.

Cloning Methods

Cutting the branches off of a healthy mother plant requires the trimmings to be about 6 to 8 inches in length. Also, ensure you leave at least a pair of leaves on the branch of the original plant so that two new branches can grow back.

Cutting the branches needs to be done from the bottom. If you cut the branches from the top then the growing process won’t be as productive. Furthermore, planting the clippings which you cut from the bottom will promote faster rooting.

The Rockwool Technique

Aside from the traditional way of cutting the branches off of healthy marijuana plants, there’s also the Rockwool Method. When you take this route, all you need to do is cut off healthy clippings from healthy plants. You also need to cut off most of the leaves but make sure you leave the ones at the top intact.

Next, you need to dip each clipping in a rooting powder or gel. Place the trimmings in a rockwool cube placed under a CFL light. Ensure that the humidity is over 90% while the temperature is about 72 to 75 degrees Fahrenheit (22 to 24 degrees Celsius).

The roots of your cloned plant should appear in about 8 to 12 days. Also, ensure that the rockwool cubes are soaked in water with a pH level of 5.5 for a few hours.

The Potting Soil Technique

Taking away all the mature leaves found on the stalk will use all of its energy and resources for sprouting roots. This procedure is called the potting soil technique, and you should also wet the bottom part of the sliced stalk. Don’t forget to dip the stalk in a rooting gel or powder.

Next, you should stick the cut plant in a saturated potting soil underneath CFL lights. The trimming should remain in the pot while the roots are forming.

The Water Technique

Traditional cloning methods require you to only remove the mature leaves from healthy mother marijuana plants. However, using the water method should also let you remove the mature leaves from the trimmings. Acquire a container like a plastic bottle and fill it up with water treated with plant wood afterward.

Submerge your clippings into the treated water. Leave the trimmings there while mixing it up every couple of days. In doing so, there won’t be a buildup of algae. If by any chance there is an algae buildup, then you should immediately change the water.

Furthermore, using the water method requires you to make sure your plants don’t get hit by direct sunlight. Indirect sunlight is key for new leaves to grow at the top of the new plant. The growth of the new leaves and roots should happen approximately at the same time. You’ll know if you’re doing it right if you see a nice ball of roots.

Taking Care of Your Clones

Don’t forget to take care of your cloned marijuana plants during the entire growth process. Always make sure the clippings are in an area where it’s a bit warmer than room temperature. Shoot for temperature levels of about 72 to 77 degrees Fahrenheit. Also, you don’t have to water the plants when they don’t have roots yet as it won’t do any good. Instead of watering the trimmings when they’re still rootless, you can spray them with water several times a day.

Contamination may take place but on rare occurrences. However, if your marijuana clones do get contaminated, then it could negatively affect the rest of your batch. Remove the contaminated specimen immediately to avoid further infection.
