It is best to take clones off of a plant in the vegetative stage. When you take a clone off of a flowering plant more energy ill be used to switch back into the vegetative stage.Your mother plant or “donor” plant should be a healthy, established plant so you can take healthy clones. You do not need much to root your clones.
All you need is:
- A plant to take clones off of.
- A propagation tray and dome.
- Your choice of propagation media (i.e. peat plugs, rockwool, etc…).
- A cell tray to keep your clones separated.
- A clean sharp blade preferably a scalpel because they come sterile in a package (some blades have an oil on them which can interfere with the cloning process).
- A rooting agent like Clonex or Mad farmer Root it.
- Filtered water.
- A mild nutrient solution is also helpful in keeping the clones “feed” throughout the rooting process (Clonex liquid clone solution).
Now you are ready to begin.
- Choose a branch or stem that has at least 2 or 3 sets of leaves. (about 3″-6″ long).
- Locate a spot on the branch between, or next to, a set of leaf nodes where your cut will be made (leaf nodes are where the branches come out of the stem). Leave at least one set of nodes above the cut.
- Make a clean, neat, 45 degree CUT with a razor blade or scalpel. Be gentle, it is important that you do not damage the branch while handling. You can use a pair of scissors to cut all of your clones you just have to immediately put them in a cup of water (preferably filtered). Then you can bring your fresh “cuts” to your cloning area.
- Next, remove the lower 1 – 2 sets of branches (stems and leaves) so that the bottom 1″-2″ is just stem. leave the upper sets of leaves to be placed above the growing medium line. If you had to take a cut off of a flowering plant, trim any flowers or buds that remain.
- To prevent an air bubble (embolism) from lodging in the stem where the cut is, immediately dip the base of the cutting into a quality cloning gel, like Mad Farmer Clone Root It.
- Gently place the cutting into your growing medium. If media is hard you can use a tool (like a BBQ skewer) to make the hole in the media so it is easier to insert the cutting.
- Check your growing medium and transfer cuttings once roots appear or a strong root ball is established.
- Repeat steps for all of your cuttings you made
Tips On Cloning:
- The quality of your water should be considered. Using reverse osmosis or ,drinking water or any filtered water would be a good choice.
- Keeping the humidity high (just until roots begin to emerge) aids in rooting your cuttings. A plastic humidity dome or tent will increase your success rate.
- Never let your growing medium dry out. Keep just enough water in the bottom of your propagation tray to keep the humidity level up but not to saturate the plugs.
- If your cuttings show signs of wilting, they may not be getting enough air. It is recommended to get a dome with vents on it so you can allow some air flow when needed. Cut some holes in your humidity dome/tent to allow air ventilation. Over watering will kill your cuttings. Never leave any water standing in the tray. It is best to briefly water the plants and then transfer them to a dry tray.
- Your pH should be between 5.5 and 6.2 by the time roots begin to show.
- Rockwool should be pretreated by soaking overnight in water with a pH of about 5.0 5.5. Be very gentle when taking cuttings. They can shock easily when cut.
- Take your cuttings (clones) be taken from healthy plants, not sick ones.
- Use a sterile growing medium; be it rockwool, peat plugs, soil, vermiculite, perlite, sand, etc. Never use soil from your garden. remove
- Keep your growing medium warm at all times. Bottom heat (with a heating mat) will help cuttings root faster Say between 75-85F (24-30C).
- Avoid transmitting disease to open plant wounds. Sterilize your tools before each use if possible.
- Try to keep all your cuttings around the same height. This allows each cutting to receive the same amount of light.
- If you are using outdoor sunlight, screen your cuttings from the direct sun or place in a shady area under a tree. If you are using fluorescent lighting you may (and should) place your lights within a few inches of the tops of your plants without burning them.It is recommended to use just one 2′ T5 fluorescent per propagation tray.
- Give cuttings a full 18 hours of light & 6 hour night cycle is recommended for optimum results. Every plant and growing situation is different, so the length of time it takes roots to appear will vary from a week to a month or more depending on the type of plant (and environment).
