If you find yourself needing to learn how to reveg weed plants to make new clones, here a are a few tips to help you increase rooting success.
It’s always best to take cuttings from marijuana plants in the vegetation stage of growth. But sometimes shit happens and you need to clone from a flowering plant. Knowing how to reveg weed clones from flowering plants is critical.
How to reveg weed clones
In many ways the process of taking clones from flowering plants is similar to vegging. Try to take cuttings from non woody growth using a sharp razor blade that has first been disinfected.
Remember to leave one node of growth for under the soil. Your goal is to ake 45-degree angle cuts below this node to maximize the exposed area of the inner stem. Doing this underwater is ideal to avoid an air bubble forming at the cut end. Take a slightly longer cut off the plant, then place this cutting in a small bowl of water and recut at 45 degrees.
Apply a rooting gel or powder to cover the cut end and the nodes that will remain in contact with your medium. Some growers dip cuttings first in antifungal mixes to avoid issues down the line. Place flowering plant cutting in your growing medium of choice. See more info about cloning in coco or cloning in rockwool cubes.
Soil, coco, or rockwool plants should be placed under gentle light in a humidity dome. Avoid high wattage metal halide or high pressure sodium lights. Fluorescent tubes placed a few inches from plant tops are perfect for cloning.
Using a heating pad under your tray will help speed up rooting. Your clones love a warm humid environment.
One important tip learned from an early failure when I was learning how to reveg weed clones: make sure to use a light cycle of 18 on then 6 off (or 20-4). Since the flowering response in weed plants is triggered by 12 hours of uninterrupted darkness, avoid using 24 hour on lighting (which can be done when clones are taking from vegging plants). If you don’t provide a shortened dark cycle of 6 or 4 hours the plant can’t reset itself. The result is that flowering will continue and the clones won’t root properly.
