Want to Grow One Cannabis Plant in Your Home? [Know This]

In America, there are now more states that allow you to use marijuana either recreationally or medicinally than states where it is entirely illegal. As legalization spreads throughout the country, an increasing number of state legislatures are also permitting the growth of marijuana at home. There are, of course, strict rules to follow, even in places where you can grow up to six cannabis plants.

If you enjoy a casual smoke now and then and live in a state where it is legal to grow weed at home, you’re in heaven! Producing a single marijuana plant is pretty straightforward, and we’ll show you how to do it below. First, let’s look at the states where you are permitted to grow a marijuana plant at home.

How to Grow a Single Marijuana Plant

As well as being a lot of fun, it is a good idea to grow a single plant because you know precisely how the plant was treated. If you are a newbie to the growing process, it makes sense to start with one plant. You can focus all of your attention on it, which should increase the quality.

It’s also a much better bet for security. Even if you live in a state where it is illegal to grow, the chances of law enforcement wasting time and resources to break into your home are slim (although we still don’t recommend trying it). It is easier to conceal a single plant from prying eyes because you can keep it in a room in your home. You can even hide it amongst larger plants in the garden!

Growing marijuana is easier than you think because it is a flowering plant. It instinctively knows when to begin growing buds (when sunlight diminishes to a specific point), and these buds grow annually in the fall. It is best to grow your single plant indoors, which means finding a way to ensure it gets at least 12 hours of light exposure daily.

Experts recommend allowing the plant to remain in its vegetative state for at least a month (six weeks is better) before it enters the flowering stage. In these early weeks, your plant needs a minimum of 16 hours of light a day. Here’s a quick and easy guide to growing a cannabis plant.

Get the Lighting Right

Once you choose to grow indoors, you have to invest in a lamp. Ideally, your plant will be located near a window so it can get several hours of natural sunlight. Then, the lighting only has to work for a few hours a day. If you need discretion and plan to grow the plant in a closet or hidden room where it is really close to the light, look for an energy-saving light such as a 24w LED. Otherwise, get a 250-watt HID bulb or lamp.

Check your plant regularly, and if it begins stretching and reaching up rather than outwards, it is a classic sign of the marijuana not receiving enough light. If you can afford it, invest in a VHO lamp, because it will help your plant grow significantly faster than when you use conventional lighting.

Don’t Forget Temperature & Humidity

Ideally, the plant will grow in daylight temperatures of 70-80 degrees Fahrenheit and 55-65 degrees at night. Make sure the area around the plant is relatively dry, because it helps resin to coat its surface. Too much humidity results in broader leaves which don’t produce good quality weed. If the humidity level is too high, consider investing in a dehumidifier.

A fan is another must-have because it can help keep the temperature in check if your plant is exposed to powerful lighting. Your marijuana also needs fresh air to ensure it gets the carbon dioxide it requires to thrive. Fans create wind which causes mild stress to the plant. This is a good thing because it helps the plant generate more terpenes and cannabinoids, so you can enjoy more potent and flavorful weed.


The trouble with tap water is that it contains chlorine, something that cannabis doesn’t like. To remove the chlorine, let your water sit in an open container for at least 24 hours. If there is a lot of chlorine in the water, purchase anti-chlorine drops at the pet store.

The amount of water you use depends on how much soil your weed is planted in. For example, two quarts of water is enough for two gallons of soil. It is better to water heavily and infrequently than small amounts regularly because it allows for even moistness in the soil. Make sure the plant’s container has some drainage holes at its bottom. If the top of the soil feels dry, wait a day or two before watering, because the bottom could be moist.

Germination & Planting

We have a quick germination guide on the site. The process only takes a few days, and you’ll know the seed is ready for planting when its taproot appears. You don’t need a container any bigger than a five-gallon pot; just make sure you wash it so it’s free of contaminants. Give the newly germinated seed plenty of light after it is planted and keep your lights around two inches from the soil at the beginning. Don’t touch the taproot when transporting the seed, or else you could break it.

Growing Your Marijuana Plant

The vegetative stage sees the most substantial period of growth in the plant’s height, branches, and leaves. Make sure it is exposed to light for 16-20 hours a day. The bigger your plant gets during this 4-6 week period, the larger the buds it produces.

Trigger the flowering stage by reducing daily light exposure to 12 hours. Your plant should remain in this stage for 8-10 weeks before it is ready for harvesting. You harvest by removing the buds and any leaves that curl around them. Hang the plant matter upside down so it dries, and store it in a glass mason jar.

Close the lid tightly but don’t pack the jar with the weed; it needs some space to cure correctly. Open the jar a couple of times a day for a few minutes during the first week. Then, open the jar every couple of days for a few weeks. Once you believe the aroma and texture are ideal, it is time to enjoy the fruits of your labor!

Final Thoughts on Cultivating Your Own Cannabis Plant

Overall, there are 16 states in America where it is legal to grow a weed plant in the home. However, most of these states only allow MMJ cardholders to cultivate. Before you attempt it, make sure you are adhering to your state’s laws or else you risk imprisonment and a considerable fine.

If everything is legal and above board, follow our tips on growing a single cannabis plant. It may seem like a lot of work, but in reality, most of the process involves sitting and waiting. The biggest threat to a good yield is impatience as growers rush the vegetative and flowering stages or fail to cure or dry the plant correctly.
