After your clones have been properly cleaned and transplanted into their new medium, make sure to keep them quarantined for a few days to a week. Doing this will protect the rest of your garden if they do develop problems, and you’ll be able to pull them out easily.
Don’t fertilize mother plants for a few days leading up to taking cuttings. This will allow nitrogen to work its way out of the leaves. When you take cuttings, an excess of nitrogen in the leaves and stems will trick your clones into attempting to grow vegetation instead of diverting energy to rooting.
It’s important to know the origin of your clones because that’s where problems originate—diseases, pests, incorrectly labeled genetics, and unknown pesticide residues can come with a mystery clone.
If you’re using cubes of any kind, you’ll need to invest in a tray, a tray-cell insert, and a dome. The clones will go in the cubes, the cubes into the tray-cells, and all of that sits in a tray which will hold water. To keep in humidity, make sure to use a dome over your tray, and you may even want to use a heat mat.
Take this time to properly clean your clone with whatever IPM solution you deem fit. A popular method for cleaning new clones involves dipping them into a light solution of whatever safe and approved pesticide you choose.
Check your clones daily to make sure they have enough water by checking the bottom of the tray or auto-cloner. To increase humidity, you can spray water on the leaves with a spray bottle. If any clones die, discard them so they don’t cause mold in the rest of the clones and also to give the remaining clones more space.

How to take a cutting from a cannabis plant
Most of the time, these clones come from growers who focus solely on producing clones, but sometimes cuttings will come from a third-party source. When purchasing clones for your home garden, always ask your shop where they came from. If you can’t get a legitimate answer, find another source.
Many diseases can be difficult to detect in cuttings, but there are a few visual cues that can be seen early on. A lack of vigor is a major cue—check for limping leaves, irregular or mutated growth, and discoloration.

Cannabis clones are cuttings from a marijuana plant – these cuttings make roots of their own and grow into an identical plant as the “mother!”
But how do you know which plants are going to be good when you have to clone in the vegetative stage?
I believe people should be able to grow cannabis in the privacy of their own homes! I have made it my mission in life to build the best growing resources available so anyone with an internet connection can become an advanced grower!
Cheap CFLs or other fluorescent grow lights like T5s are great cloning lights, as they’re not too intense. If you have just a small tent or cupboard to keep your clones, you can find CFLs at the grocery store, home improvement stores, even your local mini-mart! FLuorescent grow lights can be kept about 8-9″ above your clones.
9.) A cannabis clone from a flowering plant will grow differently at first, this is normal!
After harvest, you will know which plants had the best yields, growth, etc. Keep the clones you took from these best plant(s). These clones will become your “mother” plants which you can take further clones from whenever you need new babies.
Your clones need to get their water through their leaves right now because their roots haven’t formed.
Some clones take longer to root. I’ve had a clone that didn’t really do anything for almost a month (it didn’t wilt or grow) and I was just about to throw it away before it suddenly exploded with new growth and became a healthy adult plant. However, it’s usually a lot easier to take many extra marijuana clones and throw away any that are taking longer than the others to make roots.

Marijuana or Cannabis Sativa is a perfect species for asexual propagation (i.e. propagation via cuttings). To clone your favourite cannabis plant you need the following basic material:
7. After 8-10 days, if the substrate begins to dry, fill the greenhouse with one or two centimetres of water and leave it for 10-20 minutes so that the substrate gets moist again.
8. After 12-14 days, remove the greenhouse cover. If after one hour the marijuana cuttings remain upright, leave them uncovered and continue spraying a few times a day. On the other hand, if after an hour the cuttings lose strength, spray them and put the greenhouse cover back. Try again a few days later.

2. Prepare the substrate. If you are using Jiffy pellets, soak them in warm water (pH around 6) for 10 minutes; if you are using rockwool, you should soak them during 24 hours in water (pH=4.5) and add rooting fertiliser until reaching an EC value of 0.60. If you are using soil, just fill the pots or cells with your substrate.
5. Close the greenhouse properly and don’t forget to open it and spray the marijuana plants with water once a day.
6. After 3-4 days continue to open and spray the plants every day, but this time leaving the greenhouse’s vents open.

4. Place the cuttings in the greenhouse and spray them with water. Once covered, place them under a fluorescent light with a 18/6 photoperiod.
