How do I cut a cannabis clone?

It is simple to take a cutting from your cannabis plant to take a clone, and it is made that much easier with a good pair of sharp cutters to get a clean and smooth cut. Select a tip of the plant where growth is vigorous and select a growth tip that is located nearer the bottom half of your plant (as these cuttings will contain more rooting hormones). Cut the plant just below where there is a new growth top – you want the clone to be around 5-8 inches long and it should be cut at a 45 degree angle. Now you have your clone!

Step by Step Guide for building your own Bubble Cloner

What’s so great about building your own bubble cloner is that most of the items you are likely to already have in your home or are very cheap to get your hands on at the local store.
To make a bubble cloner you will need:

  • Plastic container with a lid
  • Duct tape for light proofing
  • Drill
  • Glue gun
  • 2 x air stones
  • Air line and pump
  • Rooting concentrate

Step One: Lightproof your container

Using duct tape or another dark tape, thoroughly cover the box so that no light is able to seep in. This involves wrapping the tape around the box itself and the lid part if this is of a lighter/transparent color.

Step Two: Cut your holes

Depending on how many clones you are going to cultivate, cut out the desired number of holes in the lid of your plastic container. You also need to drill a small hole either in the side or the top of your cloner so that the air hose and pump can be connected to your air stones.

Step Three: Secure your air stones in place

You now need to secure your two air stones to the bottom of your plastic tub (in case you don’t know, air stones are small cheap devices that create dissolved oxygen in a water solution – to put it simply, they create the bubbles you need with the assistance of an air pump). To make sure these stay in place the best thing to do is glue these in place with a glue gun – that will ensure they are not going to float away.

Step Four: Feed your air line through

Now you’re almost there, all there is left to do is to connect the air hose and pump to the air stones so that the whole system can get started. You can do this by feeding the hose through the hole that you created earlier and attach it to the air stones (you can use a tube splitter to connect one hose to two air stones).

Step Five: Add a root solution

It’s a good idea to add a liquid concentrate to your water that is effective at encouraging root growth, with this in place your clones will have more chance at surviving and developing healthily. Both organic and non-organic liquid concentrates are available whatever your preference is.

Step Six: Add your cuttings

Your bubble cloner is now all set – all you need to do is add your cuttings. Some growers like to place rubber plant holders or stoppers into the holes to secure their plants and others prefer rockwool – see what works best for you but both can easily be purchased from your local hardware store or online. Make sure that your cuttings aren’t touching the water solution as the bubbles will enable them to come into the contact with the solution a sufficient amount. Also, it will help the roots to grow faster if they are searching for the water.
