A clone is a cutting off a plant that ultimately grows roots. Once a root system is established, the clone can then be planted to produce a new plant that is exactly the same as the plant it was taken from. Knowing how to clone marijuana plants is just one more aspect of cannabis cultivation. When you know how to clone weed, the whole growing game changes. Cloning gives you the opportunity to keep your favorite strain going for years and can significantly improve your chances of a successful harvest and overall yield.
Why do growers use clones?
Clones are a way for growers to ensure that their plants grow at more or less the same pace, going through each stage of their lifecycle at the same time. This is hugely beneficial to growers and can significantly increase the success of one’s harvest.
Knowing how to clone weed allows you to create identical replicas of your favorite plant time and time again. Find a strain that you love? Cloning it lets you continue to enjoy it harvest after harvest. I’ve been gifted a few Bubblegum clones in the past that are rumored to have been circulating for years.
Learning how to clone your cannabis plants will take your cultivation skills to another level entirely. Read on to find out just how easy cloning weed can be.
How to Clone Weed
Once you’ve got it down, cloning weed becomes like second nature. There are actually a few different methods of cloning. These include cloning in water, soil, and rockwool. Each method is simple and what works best for you pretty much comes down to personal preference.
Select Your Mother Plant
You’ll need to choose what plant you want the “mother” to be. Select a healthy female in its vegetative state. The plant you clone from should be at least 8 weeks old and will need a little prep work before clones are taken.
To prepare your plants for cloning make sure that you stop giving your plant nutrients for a few days before you plan on cloning it. This helps remove some of the nitrogen in the leaves of your plants which can significantly increase the chance of your cuttings taking root. Too much nitrogen will make your plants think they need to continue with vegetative growth rather than grow new roots.
How to Take Cuttings
When it comes time to take cuttings, you’ll want to take them from the lower branches of your plant that look the healthiest. Cut branches that are approximately 8-10 inches long and have quite a few nodes on them. If you plan to use rockwool for your cuttings, cut the stem to equal the size (or as close as you can) of the rooting hole.
When you take your cuttings, it should be done at a 45-degree angle. This helps increase the surface area from where the roots can spout. You should also cut larger fan leaves of your cuttings in half to redirect the energy from the leaves and instead focused into the roots.
Things You Need
Once you’ve chosen your mother plant and are ready to get started, you’ll need a few basic tools to get you going. These include:
- A sharp razor, knife, or trimming shears
- Rooting gel or powder
- The medium you will use to clone (water, soil, or rockwool)
How to Clone Weed in Rockwool
Using rockwool for clones is one of the most popular methods. It’s quick and easy and typically offers very favorable results. First, soak your rockwool cube in water with a pH balance of 5.5 for about 2 hours. Then, take your healthy cutting and trim most of the leaves off, save for the few at the top. Next, dip the bottom of your cutting in your cloning gel or powder and insert the stem into the rockwool cube.
You’ll want to place your cut clones under at least 18 hours of light a day. A CFL bulb will work fine for giving cutting the light they need to begin to root. For best results, clones in rockwool should be kept at a temperature between 72-75 degrees Fahrenheit (22-24 degrees Celsius). Humidity level should be over 90%. Using this method should ensure roots begin to sprout in 7-12 days.
How to Clone Weed in Water
Cloning weed in water is possibly the simplest method of cloning there is. You can literally take your cutting (making sure it was cut at a 45-degree angle), remove all the mature leaves, and stick the stalk in a cup of tap water. Keep the cutting in indirect light and you should see roots begin to develop in 2-3 weeks.
Adding cloning gel or root hormones can significantly increase your chances of root development in water. However, this isn’t necessarily required. Keeping water fresh (change it daily) and making sure its pH balanced at 5.5 can also increase your success in cloning weed in water.
How to Clone Weed in Soil
Rooting your clones in soil is another very simple cloning technique. Simply take your cutting from your mother plant at that 45-degree angle and remove any mature leaves that remain on the stalk. Dip the stalk in water and then dip it into your cloning gel or powder. Immediately stick the stalk into soil that has been saturated with water. If you’re using soil with nutrients already added to it, you’ll want to flush it to ensure your cuttings aren’t getting too many nutrients (which could hinder root development). Roots should begin to sprout in around 2 weeks.
Final Thoughts on How to Clone Weed
These are the basics to get you going on cloning your very own cannabis plants. To ensure your success, you might want to think about putting your clones under a dome that provides an atmosphere conducive to root development. And always make sure you’re working in a sterile environment. Treat your clones with the tender loving care they need when they’re young and you’ll find they grow into healthy, mature cannabis plants that grow gorgeous resinous flowers.
