The state of Illinois legalized marijuana for recreational use in 2019, and now many people wonder if they can grow their own medical marijuana at home. You can currently grow your own marijuana if you have an Illinois medical marijuanas card, but there are many restrictions surrounding this. In this article, we’ll discuss the current Illinois marijuana laws and everything you need to know about growing marijuana legally and how to grow weed on your own. 


Right now, recreational marijuana users in Illinois cannot grow their own plants at home. However, you can grow your own plants if you have a medical marijuana card. Illinois offers medical marijuana cards for patients that suffer with chronic health issues and could benefit from using medical marijuana. 

Illinois Home Grow Rules

In order to grow marijuana at home in Illinois, you must be over the age of 21 and possess a valid medical marijuana card. Many people wonder – how many plants can you grow with a medical card? Right now, Illinois allows you to grow up to five plants at home. These plants can be at least five inches tall. Growing your own plants at home ensures you will still have a supply in the event of a shortage, which has happened in the past. 

All medical marijuana grown at home must be stored in a locked room. No minors under the age of 21 should have access to this room, and it should also be out of public view. If you rent your home, you will need to get authorization from your landlord in order to grow marijuana. Keep in mind that many landlords will not allow this, especially if you live in a no-smoking building. If you live in federally subsidized housing, you will not be able to grow medical marijuana at home. 

There are legal consequences for those who are caught growing weed illegally in Illinois. You could be subject to fines or further legal actions if you are caught growing marijuana in Illinois without a medical card, if you are caught growing more than five plants, or if you are not growing your marijuana in an approved space. The exact consequences for growing weed illegally will vary depending on the scenario, but can include fines and jail time. 

Who can grow medical marijuana at home in Illinois? 

Not everyone can grow their own medical marijuana in Illinois. You must be over the age of 21 and have a valid medical marijuana card. Although you can get a medical marijuana card when you are under the age of 21 in Illinois, you cannot grow your own medical marijuana. 

In order to get a medical marijuana card in Illinois, you must have one of the state’s qualifying conditions. When compared with other states, Illinois has a very long list of conditions that qualify for a medical marijuana card, so it is fairly easy to get approved. Although marijuana is legal for recreational use in Illinois, there are still benefits to getting a medical card. In addition to being able to grow your own marijuana, you will also pay less in taxes on marijuana, be able to purchase larger quantities, and receive priority in the event of a shortage. 

Many people wonder how to grow cannabis at home. In order to grow your own weed, you will need enough space for the plants to grow, and you will need a setup that provides the right amount of light, water, and air flow. You can purchase technology specifically designed for growing cannabis, but these setups can be expensive. 

For most people, it makes more sense to buy your cannabis from an Illinois medical dispensary. Cannabis products from dispensaries are subject to strict production rules to ensure they are safe and high-quality. However, there are some scenarios where growing your own marijuana may make more sense for you. If your medical condition requires you to use very large quantities of marijuana for treatment, an at-home grow setup could be more efficient. 

Caregiver Growing Rules

Minors in Illinois who have one of the state’s qualifying conditions can still use medical marijuana with the help of a registered caregiver over the age of 21. Patients who cannot physically visit the dispensary can also designate a caregiver. Caregivers can purchase and administer medical marijuana for their patients, but cannot consume any medical marijuana themselves. 

The laws about caregivers growing cannabis at home are the same as those for standard medical marijuana cardholders. They can grow up to five plants at home, but they must not be accessible to anyone under the age of 21 and they must be kept out of public view. Caregivers cannot consume the marijuana they grow – only the patient can use it. 

How many plants can you grow with a medical card?  

When growing marijuana legally in Illinois, you can have up to five plants that are at least five inches tall. If you are caught growing more than five plants, you could face legal consequences. Home growing has been legal in Illinois for medical cardholders since the beginning of 2020. Since marijuana laws are consistently evolving throughout the United States, we could see this change in the future. 

Marijuana and Housing Laws

Your housing situation is going to affect whether you can grow marijuana at home or not. If you own your property, you will be able to grow your own weed if as long as you have a locked space to do so that it is out of public view. However, if you rent your home, your situation is going to be a bit different. 

Those who rent their home must get their landlord’s permission in order to grow marijuana legally. This can be tricky, especially in small apartment buildings where it would be difficult to keep the plants secure. It’s also important to note that those living in federally subsidized housing cannot grow their own marijuana under any circumstances.
