growing weed day by day pictures

If you’re growing outdoors in the Northern Hemisphere, growers usually get their seeds between February and April, and you should start your seeds by the end of April. Some growers will start their seedlings inside in a more controlled environment because seedlings are more delicate, and then put their seeds in the ground outside once they’re a little bigger. If you’re growing clones or autoflowers, you have a grace period of another month or so. Plants usually need to be outside, in the ground, by the end of June.

The growth stages of marijuana can be broken down into four primary stages from seed to harvest:

At this stage, the plant is vulnerable to disease and mold. Keep its environment clean and monitor excess moisture. Be sure to give it plenty of light.

When should you grow marijuana?

Marijuana light cycle: 16 hours a day.

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.

Marijuana light cycle: indoor—16 hours a day; outdoor—at least 6 hours of direct sunlight (“full sun”), plus several hours indirect sunlight.

When your marijuana plant becomes a seedling, you’ll notice it developing more of the traditional cannabis fan leaves. As a sprout, the seed will initially produce leaves with only one ridged blade. Once new growth develops, the leaves will develop more blades (3, 5, 7, etc.). A mature cannabis plant will have between 5 or 7 blades per leaf, but some plants may have more.

If you buy a clone from a grower or breeder it will be a seedling, so you can skip the seed germination phase.

Marijuana light cycle: 12 hours a day.

Notes on marijuana growth phases.

If you need to determine the sex of your plants (to discard the males), they will start showing sex organs a few weeks into the veg stage. It’s imperative to separate males so they don’t pollinate the females.

Buds typically grow the most toward the end of the flowering life cycle. You probably won’t notice much budding out at the beginning of the flowering stage, and it will slow down toward the end of the cycle, when buds become fully formed.

Once your seed has germinated , or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.

Seedling stage length: 2-3 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.

Be mindful to increase your watering as the plant develops. When it’s young, your plant will need water close to the stalk, but as it grows the roots will also grow outward, so start watering further away from the stalk in the soil so roots can stretch out and absorb water more efficiently.

It’s important to know these stages and how long each lasts to know what the plant needs and when. Knowing where your cannabis plants are in their life cycle will dictate when to prune, train, and trellis your plants, and when to harvest.

Cannabis plants go through a series of stages as they grow and mature, and those different growth stages call for different amounts of light, nutrients, and water.

If you’re growing weed indoors, you can grow whenever you like. Keep in mind that the outside environment will affect your grow space—you may need to add heaters in the winter or fans and ACs in the summer. Other than that, you can start seeds whenever you like and flip them into flower whenever you like, depending on how big you want the plants.

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.

These pictures show marijuana, also known as cannabis or weed, in varying stages of growth, processing, and use. You may be concerned about plants you find growing in and around your home. Or, you may wonder whether what you discovered in your child’s room is marijuana or indicates your child may be using marijuana.

First of all, don't over-react. Before you force your child into a professional drug treatment program that you may not be able to afford and they may not even need, take a step back and try to evaluate the situation.

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 you look closely at a marijuana bud, you will see the fine "hairs" and leaves that make up the bud after it is dried.

If you find a larger quantity of processed marijuana buds in your home, someone either has an expensive habit or they are selling weed to their friends.

Forty-four percent of all students have tried weed by 12th grade according to the National Institutes of Health.   That means that your child probably has friends who are smoking marijuana or at least know someone who is.

Marijuana buds are higher in THC than other parts of the plant and are sold at a premium. As marijuana has been increasingly bred to produce more buds, you may find this type of marijuana in your home. It is probably much more potent than the average street-grade weed.

You may find a small amount of marijuana your child has acquired for personal use to smoke. It is probably readily available in your community.

Whether or not adolescents become involved in drugs—or stay involved—may be related to their parents' attitudes about drug use. Having a matter-of-fact, rational discussion with your child about marijuana may be the best way to approach the situation.

Even if you live in a jurisdiction where marijuana is legal, there are age restrictions and your child can end up on the wrong side of the law. You should prepare to have a conversation with your child about the risks involved in using or selling marijuana when underage.

If you find plants around your home that look similar to the marijuana plant in the photo, someone in your household is trying to grow their own weed. The plants have changed considerably in recent decades as they have been bred to produce more buds.

Marijuana is dried and chopped up to prepare it for use and sale. The stems are usually removed.

Your child's involvement in marijuana may have just been a passing curiosity, or it may be more than that. Before you react, you need to assess just what your child's level of involvement is with marijuana.

How to tell if your plant is a male or female.

Cannabis growth is made up of a series of stages that plants undergo during their lifecycle. Each stage during the cannabis cultivation process requires its own unique demands, including different levels of light, water, and nutrients.
