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.

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 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.

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.

It may be that your child has experimented with marijuana use or tried it a couple of times with their friends. That happens a lot more these days than it may have happened when you were in school.

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.

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 do you do that? The best advice available is the simplest—ask your child.

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.

Of course, your child’s use of marijuana may be more involved than simple experimentation, depending on how much of the drug you found. If so, they may not be as willing to talk to you about it. In this case, you will need to educate your child on the legal risks of transporting or selling marijuana.

Parents may want to know what marijuana looks like in all stages of development and use. See photos that can help you check what you find at home.

For those who regularly use cannabis for therapeutic or recreational purposes, the notion of cultivating plants for personal use may be appealing. Growing cannabis can be straightforward, but as with most crops, yield and quality can be improved with awareness of the plant’s life cycle and growth requirements. When it comes to growing cannabis, the first decision is to determine whether to cultivate indica or sativa plants.

Is there really a difference between indica and sativa?

Up until recently, the cannabis plant was classified as sativa, indica, ruderalis, or the elusive afghanica, which originated in or near Afghanistan. The usefulness of this cannabis taxonomy for contemporary consumers has been questioned by experts, including Dr. Ethan Russo , who has recommended abandoning this classification system. Due to human intervention, very few modern cannabis plants are purely indica or purely sativa. Russo argues that it’s more helpful to identify biochemical compound content, such as cannabinoids and terpenes .

However, differentiating indica from sativa remains very useful for cannabis cultivators. Using morphology, or phenotype, is the most common way to classify cannabis cultivars . Indica and sativa, the most commonly recognized cultivars, have distinctive physical features and growth traits. Understanding their respective growth cycles and how to tend each plant type will help ensure optimal growth and bud output.

Hybrid strains are also commonplace, with many growers opting for plants that blend the most desirable properties of both sativa and indica. Hybrids may be indica- or sativa-dominant, like Sour Diesel. White Widow exemplifies a balanced hybrid cultivar.

Identifying Sativa Plants

Sativa cannabis plants originated close to the equator, thriving in temperate regions with mild winters and long summers. Sativa strains can reach up to 10 feet tall and are characterized by sparse foliage and light-green, thin-fingered, delicate leaves. They boast a long flowering period as there is no climatic impetus to reproduce rapidly and disseminate seeds. The extended flowering period is somewhat offset by a reduced vegetative period, in which no flowers are present. Sativa is known for generally lower yields than their indica counterparts.

Sativa cultivars are not ideal for home growers hoping to cultivate indoors, or within a restricted space. These plants generally require balmy temperatures and relatively high humidity where they thrive when given have space to grow.

Identifying Indica Plants

Cannabis indica cultivars are smaller in height than their sativa counterparts with broad, dark-green leaves and a bushier appearance. Indica plants are popular among home growers due to their high yields and shorter flowering periods. They typically mature faster than sativa cultivars under similar conditions, producing flowers in as few as eight weeks.

The rapid flowering period occurs due to the biological need to reproduce and spread their genes before the arrival of harsh winter conditions. These cultivars also tend to have a different smell, perhaps reflecting a different terpene profile .

Indica plants were originally found in unforgiving dry and colder Asian climates, which resulted in their robust and more compact physical profile. Their short stature makes them ideal for indoor cultivation.

Preference of indica vs sativa

If you’re contemplating growing cannabis and wondering whether to grow indica or sativa, your choice will likely be guided by the kinds of effects you’re looking to experience. It’s important to note that effects have more to do with the cannabinoid and terpene makeup of the plant and less to do with its morphology. Here’s the lowdown on the differences between growing indica and sativa.

Sativa vs. Indica Cultivation Considerations

The growth cycle of any plant can be divided into the four distinct stages of germination, seedlings, vegetation, and flowering. While harvest doesn’t represent a formal phase, it does constitute a significant phase for the grower.

Germination

Some home growers elect to grow cannabis from feminized seeds, which produce exclusively female plants. This ensures none of the female flowers are pollinated by male flowers, which would cause them to produce seed, reducing the cannabinoid yield. Seeds can be easily germinated within paper towels dampened (not wet) with distilled water.

If you’re growing sativa strains from seed, aim for an optimal temperature of 75 F (24 C) to encourage germination within three to seven days. Lower temperatures will delay the emergence of the radicle (the part of the plant that develops into the root).

If you’re growing indica plants from seed, expect a slightly shorter germination period. Like sativa seeds, indica seeds require a warm temperature to germinate (approximately 71 to 75F or 22 to 25C).

Seedlings

When the beginnings of the tap root and a leaf or two appear, the seedling can be carefully transplanted. Both indica and sativa plants require special care and benefit from proper soil composition, climate control, and lighting as they are establishing root systems. The seedling stage lasts from 1-3 weeks.

Vegetation

The vegetative phase is characterized by the growth of the stem and leaves. The length of time a sativa or indica plant remains in the vegetative state depends entirely on its exposure to light. Sativa and indica plants move into the vegetative state after three to six weeks.

The sativa vegetative period starts slowly, with the stem elongating more rapidly later in the vegetative cycle. The stem of the sativa plant is fibrous rather than woody, and the leaves develop as narrow fingers. Throughout the duration of the vegetative cycle, seven to twelve leaf pairs form in a certain pattern . The first leaf pair comprises a single leaflet. The second pair has three leaflets. The third pair has five leaflets, and so on. Sativa uses less chlorophyll during the vegetative cycle than indica, resulting in light-green leaves.

Indica strains do not undergo the same stem elongation as the plant focuses on developing a thick, woody trunk to support the weight of future buds. Perhaps the most distinguishing characteristic of cannabis indica plants is their leaves. Indica’s unmistakeable fat, forest-green fingers help to soak up light and accelerate growth. Outdoors, indica plants are unlikely to grow taller than six feet (two meters), and indoor plants usually grow three feet (one meter) or less. Indica strains tend to spread out wide like a bush, with vigorous branching.

Flowering

In both strains, pre-flowers can be easily mistaken for new branches. If you haven’t used feminized seeds, the pre-flowering period is the time to separate male plants from female plants. Males must be removed immediately to avoid pollinating females unless the intention is to produce seeds. The first male pre-flowers appear as a small sac, while female plants produce a structure called a cola that looks similar to a hair and will later become a flower or bud.

Flowering occurs when the days shorten, or when the plant receives 12 hours or less of continuous daily light. Photo by: Gina Coleman/Weedmaps

Flowering occurs when the days shorten, or when the plant receives 12 hours or less of continuous daily light. You can force flowering by reducing the hours of light exposure or photoperiod, signaling to the plant that the nights are becoming longer.

Sativa strains can take 10 to 12 weeks before the flowers are ready to harvest. These plants continue to grow tall and fast throughout their life cycle and can double in height even after they’ve entered the flowering period. The overall life cycle for sativa can last up to six months, resulting in a more extended growth-period than that of indica.

Indica strains flower more rapidly than sativa, forming flowers after seven to nine weeks on average. They continue flowering for up to twelve weeks. Many indica slow their upward growth as they begin flowering, and instead become bushier, with branches and leaves fanning out. Their life span is three to four months.

Harvest

Sativa buds are ready to harvest when the majority of the trichomes, or resinous glands on the buds, appear milky-white with only an occasional clear trichome in the mix. Sativa bud structure is frequently elongated and thin, with an appearance similar to spears. However, the flower buds of sativa can also form foxtails, when the calyxes, or nug groupings, of the female buds stack up on each other.

Indica buds are tightly packed and tend to grow in a more chunky formation than those of sativa. Indica trichomes that are ready to harvest can take on a milky-translucence as well, but often appear more amber in color.
