Cloning Tutorial
By 420 - 420 Magazine

Ok guys lets do some cloning. There is tons of info about this subject already but people will always ask for more info. I think the reason for this is because most people are afraid to cut their plant. They are not fragile. Pruning and cutting usually will increase bud production. It doesn't really hurt the mother plant, the only real stressful part is on the cutting itself. Cloning is the most traumatic experience a clipping via clone will endure. You are forcing a clipping to transform into a growing plant. We are making a stem that was growing leaves to all of the sudden grow roots and undergo severe changes to survive. Because of this you should take more cuttings than you need. Don't worry, it gets easier.

Cloning. MJ plants can reproduce sexually or asexually. Seeds are from reproducing sexually while clones are propagated asexually. To be technical cloning is taking cells from the plant (for growers that means cuttings) and promoting its growth to become a plant all its own.
Before we start Lets talk a little about the good points and the bad points to cloning.

Good points are as followed. It reduces the the time to having a mature plant. You don't need high power lights to start clones, fluorescents work very well for cloning.Since clones are genetic copies of their mothers all clones will be the same sex. Taking a clone and flowering it will tell you what sex your soon to be mother is. Since clones are genetic copies, they grow at the same rate so other techniques like SOG (Sea of green) or SGROG (screen of green). The older the mother is the easier it is to induce flowering.

Here are the bad points. Clones grow slower than a F1 hybrid will because of the lost of its hybrid vigor. This also means a F1 can grow about 25% bigger than a clone. You have to start with a good mother because all the characteristics of the mother, the clones will have the same. Clones are less disease and pest resistant because of the trauma a clone has to undergo to become a plant. You need at least two different growing areas, one for veg and clones, the other for flowering. Some plants are very difficult to clone or its just not possible. Like certain unstable hybrids, Sativa with early flowering properties, or the Ruderalis with autoflowering properties like the Lowryder.

Preparations for cloning. Clones develop a stronger and faster root system when they have a high carbohydrate and and low nitrogen concentration. Flush your plants one week prior to taking cuttings and feed only water for that week. Just don't drown your plants. Since I do hydro it makes it a lot easier, just change the water in the res every other day for a week. Reverse foliar feeding will also help leech nitrogen from the leaves. Just fill spray bottle with water and mist your mother heavily everyday once for three to five days. Hormone content is different in different parts of the plants. The bottom of the plant has more hormones in it so the lower branches tend to root better and faster than towards the top of the plant. There are many cloning compounds out there but I prefer the gel. It coats evenly and sticks to the plant well. Which ever you use just read the instructions and make sure its for use with edible plants.

Now its time to get ready. Clean and disinfect your work areas and tools. Always use sharp scissors or a razor and clean with alcohol. Have everything ready and within easy reach like rockwool, scissors humidity dome ect.

Cloning, step by step.grab a firm branch and cut at a 45 degree angle and take a cutting about two to four inches in length. To not damage the bottom of the cutting. Trim off the lower leaves and node points. Then place cuttings in water. A embolism is a air bubble that can get trapped in the stem and kill the clone, this is the reason to soak cuttings in water until your ready to put in grow medium. Make sure the ph is between five and six. Do not fertilize the clones.

The first cutting.

Same cutting but removed the lower leaves and node points.
Image

Split the end to create more surface area for roots. I chose this method because is causes a stronger root system. Only draw back is it takes more time to root.
Image

Lightly scrape the skin aroung split stem to expose more of the cambium layer.
The cambium layer is where the plant generates roots.

Image

Dip end in cloning gel. I hope my rooting hormone still works. It is old and has turned into a liquid.
Image

Put clipping in rockwool or whatever growing medium. Make sure its very moist and that you press or fill your medium around the hole to keep air away from the rooting area

Image

I like to spray the dome to give a humidity boost.

Image

In about two weeks I should have some clones.

Is it ok to clone after it's passed 21 days flowering I'm at 25 days right now?

You could.

I cloned once off a flowering plant and put them back on the veg cycle. It took awhile for them grow and when they did they grew mutated leaves...single blade leaves, curling leaves, deformed leaves etc .. Those were outdoor clones and I can't remember anything about the harvest of that particular plant though I'm pretty sure things eventually straightened out

Best time to clone from a mother plant, is during veg(never flower). Every 30 days give her a haricut, and poof, 30+ clones if you have a decent sized mother. You can snip a few here and there every week if you want. But always in veg, and atleast a week or two after the last haircut(trimming down).

Thats not a fact though it depends on what u want,a normal plant that grows 1stem is the one taken from a vegging plant n if u want some buses without lst u should take a clone around the 21st day of flowering

Those are some strong tips. Thanks for sharing as I haven't read such useful information before.
