How to Clone Marijuana Plants: We are going to show you the fundamentals of cloning marijuana and show you how we clone marijuana.
First some cloning marijuana basics:
Take your marijuana clones from mothers that are at least 8 weeks old: Marijuana clones taken from younger mothers may result in weak plants, detrimental to growing your medicine.
We are using a Vision Seeds’ Chocoloco as the mother plant for our clones but obviously you can use any marijuana strain you have.
Choose your marijuana clone from the bottom of the plant: they have more of the rooting hormones needed (J. Cervantes, Marijuana Horticulture) Additionally have a cup of clean water nearby.
Remove the marijuana clone from the mother with a 45 degree cut, using a razor blade or scalpel. Don’t use scissors as you will crush the stem when you cut it. The reason for the angled cut is to give the marijuana clone’s stem more surface area from which to drink and grow roots.
Immediately after cutting, put the clone into water to prevent air bubbles from forming in the stem (an embolism). Air in the stem can prevent water uptake and result in a dead marijuana clone.
Once you’ve cut the marijuana clone, take off the lower leaves, and give her another 45 degree cut higher up the stem. Again, have a cup of water nearby to place the fresh cut marijuana clone into.
You will want to clip the fan leaves in half so the clone still has enough leaf area to aid photosynthesis but not too much to make the clone work to provide moisture to large fan leafs. The trimmed fan leaf makes it easier for the clone to process water from her roots (reduces transpiration and also keeps the leaves from touching each other).
After her final 45 degree cut, dip her in water or your cloning solution or gel (there are many to choose from) and into the cloner, rockwool or soil.
We use an aero-cloner: the bottoms of the clones are constantly misted with water. We usually just use plain tap water with no rooting hormones or gels.
WISHBONE CUT (Splitting the clone’s stem)
After you’ve taken the second 45 degree cut, carefully slice vertically through the bottom stem for a quarter to a half inch so the stem looks like a wishbone. This exposes more of the layer just under the plant’s skin (the cambrium) You will see 20-40 percent more root growth due to the extra surface area on the cambrium where the roots originate in a marijuana clone.
The two rooted clones in the video were taken three weeks apart. The wishbone clone is three weeks younger than the straight cut and has almost twice as much root mass on her.
