When cloning your mother cannabis plants you want to get the the best genetics from the mother in a clone that roots fast and grows up strong. In order to streamline this process there are a few tricks you should be utilizing. If you start with great clones the chances of having great bud are increased exponentially. A solid clone is like having a solid foundation, take care in the first steps and the plants will be more responsive to feeding, light exposure and resist pests and disease better.
Marijuana Cloning Tips
Start With a Strong Mother- Mother plants should be at least two months old before clones are taken from them. Some strains give good clones no matter how pumped up they are with fertilizer but others clone better when the soil is leached. In order to ensure you get great clones, leach the soil for a 3-5 days before cutting clones. Use 2 gallons of water for every gallon of soil to ensure all the nutes have been rinsed out. This will give you a clean canvas to work with, so to speak.
Keep Humidity High- In a perfect setting the humidity around your clones will be above 95%. This is often only achieved with some kind of humidifier or fogger. This mimics the tropical environment young cannabis plants thrive in, usually occurring in early summer or late spring. As you know as the season progresses the air will become dryer and lower humidity is best for budding, but for now, keep humidity high.
Incubate Your Clones- Clones root fastest when the grow medium is warmer than the air temperature. This means you need to warm up that medium somehow. You can do this by using a heating pad under the clone planter or you could build a light box and place the clone planter on top of that. An advantage of a light box is that the source of the heat is not in direct contact with the planter. A light box can be made out of thin particle board and a 35 watt bulb placed inside. This will warm up the clones grow medium nicely.
Cut Cloned Leaves in Half – This lowers transpiration and helps keep leaves from overlapping. Overlapping leaves are a great place for fungus to thrive. Misting the cut leaves is also a good idea since they cannot receive water from non-existent roots. These two things will ensure that clones retain as much moisture as they can while they go through the traumatic experience of cloning.
As Roots Form Give More Light- The more roots that for in your clones the more light they can handle. Once your roots have shown through your cubes start lowering your fluorescent lights closer to the tops of the clones. As you continue to see root growth continue to lower the lights accordingly. It is good to mention here that many growers make the mistake of wanting to use all the clones they cut. Some of the less healthy clones could hold back the healthiest ones. Choose the clones that are doing the best and keep the light coming. The clones that don’t look as good should be culled out or taken back to the start of the process.
If you use these tips instead of simply dipping a cutting in some hormone and hoping for the best, you will root more clones, they will root faster and the clones will be stronger and more disease resistant.
