marijuana clone cloning cannabisBy Robert Bergman

You have to know that depending on the type of marijuana plant, there are easier ones to clone and there are harder ones. Cannabis Sativas, for example, are easily cloned unlike the early Indicas which are very stubborn and you will have to take careful care of them. Here are some useful tips on how to do this.

Firstly, you have to figure out how to promote the root grow. Think about the exact place where the root will start growing before cutting it. This part of its stem has to be kept in a dark place covered by a certain wrapping. This method is the so called etiolation and it encourages the rooting process. The cutting should be made with sharp scissors of a pruner. The stems should be made sterile after each time they are cut. Do not use a dull instrument because it can crush the stem and make the formation of the roots harder. You can use a razor blade as well but be careful not to hurt yourself. A cut in an angle will make the absorption of water easier by providing a larger surface.

Secondly, the process or root formation requires air; however it shouldn’t be let close to the stem because it will cease the action of the capillaries and make the growth hard. You can prevent this from happening by immediately putting the cut under water Moreover; you can also make the cut under the running water of the sink. Then it has to remain in the rooting solution for some days. Do not just leave it in the water. It needs oxygen to sprout the roots. You can use an airy medium to make passive aeration.

Furthermore, breathing also makes the process difficult for the cutting. You can make some kind of a dome of plastic in order to lower the levels of transpiration and keep the water in the cutting so that it does not go dry. Another idea you can use is to cut a half of every leaflet in order to limit transpiration. In this way you will still have the some leaves on your stem but with a smaller surface area.

Thirdly, you have to maintain a good lighting. Do not use direct sunlight because it will heat the cutting in the dome way too much. However, a dark environment is not good for growing as well. This leads us to the conclusion that fluorescent lighting is the best solution. You can use an HID but not very close to the rooting system. Indirect sun from the window is also a good idea if the cutting is kept in a warm place.

Last but not least, don’t forget to check the pH of the soil and the nutrient concentrations for your fresh marijuana clones. When the cutting is beginning to grow this means it has developed roots and you can remove the dome. Have in mind that at first the cutting may easily die so you have to give some mist to it to make it stronger. More on marijuana clones here.

    After the death of my third cacti, I decided it would be in nature’s best interest if I didn’t try to grow a green thumb. But I did have a few questions about the cloning issue… Is cloning more prevalent now? How often do cloned seeds fail as opposed to thrive (you know, just an estimate)? Does the effect of cloning strengthen the strain over time or weaken it?

    • Chamorro

      In My experience I’ve noticed over time that cloning a clone from a clone etc, etc tends to degrade the plants structure… The plants will be smaller in stalks and beaches over time… Usually I grow a mother and take clones only from her… I don’t clone and then grow it to take clones! Nothing beats growing from Seed to Finish… Just My opinion…

      • painkills2

        Since I’m not a grower, I can only relate by remembering all I know about cloning in general. (You know, from what I learned at the movies.) Degradation is inevitable, unless the cloning is tightly controlled, as you explained. Makes sense.

        I was mentally comparing the cloning in cannabis to the cloning of America’s corn crop. But that’s not right, that’s genetic modification. I mean, what’s the right comparison?

      You can take 6-10 cuttings from a plant, grow them out to a month or so, use the best looking 2 and discard the rest(they are not the best so dump ‘em!). As long as you do this type of ‘clean up’, one can clone for many years with weakening the strain. The original OG Kush SFV pre-71 strain is clone only and they have been taking cuttings from this strain for over 40 years. If there was guaranteed diminishing results from taking cuttings this strain would be useless but it still wins cups.

      • painkills2

        Perhaps it depends on the strength of the strain you begin with before cloning? But 40 years seems like an awfully long time…

  • Blazy Face

    These are wacky directions. They are all over the place and really hard to follow.

    Also, leave the cutting in rooting solution for a couple days?!? Nooooooo way. That will kill your clones for sure. I dip mine clones in rooting solution for 10-15 seconds like the instructions say to and then it goes in the rooting medium (rockwool).

  • mile high

    cloning does not diminish the quality! it actually increases it.

  • Dalie Dough Redline

    i put 4 cuttings in 1 rockwool with out solutions / dont even cut my leaves , they go in a plastic tote with a 2 foot light throw a towel over them every 3 days soak the rockwool in bowl of water / get ready in 2 weeks you can plant .
