Vegetative stage length: 3-16 weeks
Be sure to keep a grow journal to track the progress of your plants. Looking back on your notes will help you learn from mistakes and maximize the quality and quantity of your buds.
Within the flowering stage, there are three subphases:
The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flowering.
Marijuana light cycle: indoor—16 hours a day; outdoor—at least 6 hours of direct sunlight (“full sun”), plus several hours indirect sunlight
Cannabis plants are considered seedlings until they begin to develop leaves with the full number of blades on new fan leaves. A healthy seedling should be a vibrant green color.
As the sun reaches up high in the sky, your cannabis will want to as well. Make sure all of your plants are outside by the Summer Solstice.
Male plants can also be used for:
“Herming out,” as some call it, is something that generally happens when a plant becomes excessively stressed. Some stressors include:
Enclosed by these bracts and imperceptible to the naked eye, the calyx refers to a translucent layer over the ovule at a flower’s base.
How to determine the sex of a marijuana plant
Because of this, it’s important to look into the genetics of the male plants. Their shape, rate of growth, pest and mold resistance, and climate resilience can all be passed on to increase the quality of future generations.
While both result in pollen production, true hermaphrodite cannabis plants produce sacs that need to rupture; anthers are exposed, pollen-producing stamen.
The pistil contains the reproductive parts of a flower, and the vibrant, hair-like strands of the pistil are called stigmas. Stigmas serve to collect pollen from males.
The stigmas of the pistil begin with a white coloration and progressively darken to yellow, orange, red, or brown over the course of the plant’s maturation. They play an important role in reproduction, but stigmas bring very little to the flower’s potency and taste.

If you see plants like this growing around your home, chances are they did not just pop-up in the wild—they were purposely cultivated. Cannabis plants have a palmate leaf with serrated leaflets. You are likely to recognize them from popular art. While there are plants with similar leaves, the serration pattern for Cannabis is distinctive.
Marijuana is dried and chopped up to prepare it for use and sale. The stems are usually removed.
Plastic Bag Full of Marijuana
You may also find larger quantities of marijuana in a plastic zip-lock bag. You might find smaller plastic bags with residue inside. This can trigger concerns that your child is transporting or selling marijuana rather than obtaining it for personal use.
If you see this many marijuana plants growing indoors, you have stumbled upon a major indoor marijuana grow operation. Leave the scene immediately and call 9-1-1 if it is not a legal operation.

If your child is using marijuana, you may be likely to find rolled joints of marijuana cigarettes. You may also find rolling papers. Your child may claim that these are hand-rolled tobacco cigarettes, which would also be a concern.
