Cloning is a tried and true method for continued success in your garden. To keep your favorite strain in rotation you will need to take clones.
A clone is a cutting (a small piece of plant that’s been cut off) that has re-established roots and is a genetic replication of the mother plant. This guide will take you through the steps to successfully root a cutting. Once you’ve mastered the art of cloning you’ll be well on your way to keeping your favorite genetics in rotation and having a self-sustaining garden. No more buying clones from questionable outlets or worrying about bringing in pests from someone else’s garden.
- A mother plant is a plant that has been specifically grown to provide cuttings for starting
- new plants i.e. clones.
- The cutting will be genetically identical to the mother, which is why you want to choose a
- mother that is a strong grower with good genetics. In other words, a healthy plant.
- Using a fertilizer formulated for the needs of mother plants, like MotherPlant brand
- fertilizer, is important for the successful rooting of clones. A good fertilizer for mother
- plants is one that limits excess nitrogen and provides the important building blocks for
- carbohydrate accumulation. The excess nitrogen contained in standard fertilizers results in
- low carbohydrate reserves and poor rooting of clones.
How to Clone Cannabis
Fill a 5 gallon bucket with clean water and add 1 ml. of Super thrive and about 30-35 ml. of bloom formula organic food. (I’ve had excellent results with Botanicare’s Pure Blend Pro line of Veg and Bloom formulas.) Then add approximately 5 to 10 ml. of pH up to bring the meter reading to 5.6 pH. Place your Rockwool slab into a tray, fill it with the nutrient solution, and let it soak to remove all air bubbles.
Place your hand over the Rockwool and turn the tray a full 90 degrees to pour off the excess water.
Get your mother(s), razor blade, and a pencil ready. Make sure everything is within easy reach; your answering machine is on your favorite tunes playing. Pack a bowl, roll a jay or fill the bong, take a nice big hit, and let it out. Now you are ready to begin cloning. Oh and ofcourse you will need cannabis seeds!
Cut the first shoot you see. Train your eyes to look for two leaves and a growing top. I cut shoots as short as 2? Or as long as 9? And have them all rooted in the same time frame. After you’ve got a good top with two leaves cut, insert its stem into the first Rockwool cube hole, starting at the top of the left hand corner, just like reading a book. Gently close the Rockwool around the freshly cut stem with your stick. This will prevent the cutting from drying out and it also gives mechanical stability to the rootless little cutting.
Here you see pictures of Afghani Bull rider plants in 16-ounce cups. These all came from one single mother plant. I cut 50 clones with the intent of only needing 16 to 32 of them for a budding crop; the remaining clones simply became future mothers or were given to special friends.
After you’ve got 50 clones, or you’ve run out of moms to cut, cover the tray with a clear tall dome with a few breather holes cut in the top, then place it on a heat mat in a nice safe location. Two of these trays fit perfectly side by side under a 4? 2-tube fluorescent shop light. They don?t need any more light than this for the first week. After a week you can remove the dome, then double the light by either moving it closer to the trays, or switching to a 4-tube light. (Or go for broke and throw them under a 400-watt metal halide lamp like I did.) Keep the light on for 18 to 24 hours a day.
Two or three days after you’ve cut your clones, you can remove the dome lid for a few minutes every day. Cut larger holes in the top and bottom of the lid. They shouldn’t need any water for five to six days unless it is extremely hot and dry where you live. Lift the whole tray every day and you’ll notice when it feels light and looks dry; this is good because if you keep it too wet it takes longer for roots to form. You can add plain water at a pH of 5.6-5.8 if necessary.
Within two weeks you’ll see little white roots busting Out of the bottom of the root cubes. You may now give them a light feeding with an organic bloom formula. I’ve found that a small dose of bloom food will increase the root development. They can then be separated and planted into the next larger sized Rockwool cube/slab for your hydroponics setup, or placed directly into an Aeroponics or coco coir system or, like shown here, planted directly into 16 ounce plastic drinking cups filled with Sunshine Mix #4 soilless medium, with a hole drilled in the bottom. When transplanted, its time to start your vegetative feeding program.
