The best marijuana seeds for Illinois

About Illinois cannabis seeds

Illinois has a continental climate, which means the state experiences cold winters and warm summers with frequent temperature changes. For many Illinoisans, the milder temperatures of spring and fall are the most enjoyable. Although the states' climate greatly affects many plants, you can grow cannabis in Illinois. However, if you focus on creating the best conditions, you can produce higher yields.

Illinois historically had some of the best soil for farming, but it has been depleted of nutrients so much that farmers have turned to fertilizers. That’s why it is a good idea to grow your marijuana seeds indoors. As with most traditional crops, cannabis seeds in Illinois require high nutrient levels for growth. If you are going to grow cannabis in Illinois outdoors, you might have to use a lot of fertilizer. Despite this, many outdoor growers still succeed. However, cannabis is mainly grown indoors because it requires moderate temperatures and the right amounts of nitrogen and phosphorus.

Illinois Marijuana Seeds 

Since legal marijuana is relatively new in the state, it is hard to find marijuana seeds in Illinois, let alone high-quality ones. The tricky part is choosing the right genetics that will thrive in your growing environment. Yet, there is absolutely no reason for you to give your money to any “brick-and-mortar” Illinois seed bank. For most Illinois cannabis growers, it’s easiest to source seeds is not from cannabis in Illinois, it is from an online cannabis seed bank like ILGM.

It takes quality marijuana seeds to grow healthy plants and get good harvests. One of the problems with buying cannabis seeds is that they all look alike, regardless of whether they were grown by a professional or a first-time grower in their basement. So most marijuana growers thoroughly research their marijuana seed options before they buy. This is why we provide marijuana grow guides and focus on great customer service to assist you when choosing your marijuana seeds.

However, no matter how much cannabis you grow, some seeds will still not germinate, even if they come from a professional breeder. You should keep in mind that about one-fourth of the seeds you plant will not germinate or die off. In particular, when it comes to growing regular cannabis seeds, some seeds will not germinate, and others may turn into males. When it comes to feminized seeds, some won’t germinate as well, but a lot more will turn into flowering plants since there will be no males.

With cannabis seeds, simply bury them in the ground, and they’ll start growing. Feminized seeds will always produce female plants, so growing them lets you skip the whole process of identifying the plants’ sex and tossing out the males. In turn, your crops are less likely to be invaded by stray males. A single male can pollinate an entire crop, making your females produce seeds instead of buds. When it comes to finding the best feminized seeds in Illinois, don’t risk it - just check out ILGM instead. 

For Illinois cannabis growers with limited space, it is common to grow Indica auto flower seeds or Indica dominant seeds. But if you have more space, growing cannabis Sativa varieties would probably work better for you. Once you find the perfect cannabis seed variety, you can buy several bags and store them in the fridge for years. However, keep in mind,  high-priced seeds don't necessarily mean high-quality seeds. 

More importantly, you don't want to waste time growing low-quality seeds that will not produce any yield just because they are cheap. Instead, choose an online seed bank known for providing quality marijuana seeds and excellent customer service. Buying marijuana seeds online is the easiest way to buy cannabis seeds privately and quickly. Online seed banks like ILGM provide more than just various strains to choose from; we also provide advice and support to help you on your growing journey.

Buying Pot Seeds in Illinois: What You Should Consider 

Buying pot seeds in Illinois is not exactly a walk in the park. Ideally, you should order your seeds online. The key to this is to make sure you are ordering from a reputable seed bank that guarantees their products and safe delivery. 

Other than choosing the right seed bank, you also want to choose the right seeds. An online seed bank has a massive selection of marijuana seeds to choose from. Information about those strains is on the website, as are comments of past growers. That means you can choose the perfect marijuana seeds for Illinois temperatures if you’re growing outdoors, as well as for your expertise level. Here’s what we recommend researching before selecting your perfect cannabis strain.


Everyone in the Midwest knows that the climate in Illinois isn’t an easy one. That doesn’t mean that growing outdoor cannabis is out of the question, however. Plenty of people maintain successful marijuana gardens outdoors in the warmer months and have very strong results. The main aspect to consider is whether your cannabis will grow well in the Illinois climate. Keep in mind that the hardiness zones vary depending on how far south or north you are living. 

The north has hardiness zones of 5a or 5b, which have extreme minimum temperatures of -20 to -15 degrees Fahrenheit and -15 to -10 degrees Fahrenheit, respectively. This increases to -10 to -5 degrees Fahrenheit in the lower half of Illinois, finishing up at -5 to 0 degrees Fahrenheit in the lower fifth of the state. The Chicago area, being lakeside, has a bit warmer hardiness zone of -10 to -5 degrees Fahrenheit, or zone 6a. The most successful Illinois harvests happen when growers purchase hardy cannabis seeds that do well in cooler climates.

For outdoor grows, we recommend Girl Scout Cookies Extreme Autoflower. Some may say that these are the best auto seeds in Illinois. This cannabis strain requires very little maintenance and has shorter, denser plants on average, partly because it’s an autoflower. Autoflowers are good for climates with shorter growing seasons since they usually have a quicker flowering time and can be harvested before the weather gets too cold. Additionally, keep in mind that growing indoors is always a solid option. Seeds of all kinds grow well in the right environment.


Another aspect to consider when buying seeds is your expertise. If you have never grown marijuana before, absolutely do not buy anything above an explicitly stated “beginner” level. Don’t go for the best feminized seeds in Illinois if you can’t grow them well; pick beginner seeds and coax them into producing a bountiful harvest. If you are an advanced grower, this advice doesn’t apply to you, and the sky's the limit! But for those beginners, try improving first with our free Marijuana Grow Bible.

Seed Bank  

The seed bank is equally essential, simply because you can’t know if your seeds will be reliable unless you are ordering from a reliable seed bank. For growers in Illinois, seed bank shipping is very important specifically. Your cannabis seeds should be delivered with care, reliability, and discretion. If you order from a company with lots of experience and reviews from happy customers, such as ILGM, you will be happy as well. Plus, you are less stressed because you know the seeds will arrive safe and sound. 

Where to Buy the Best Marijuana Seeds in Illinois  

When you’re looking for top-notch seeds, the seedbank is everything. Buying from ILGM will ensure you receive the best auto seeds in Illinois if that’s what you want, or just a solid, simple, beginner-friendly cannabis strain that will make you enjoy the marijuana growing process. Ordering your seeds to Illinois via seed bank shipping is only risky if you don’t order from a reliable source.

 ILGM is reliable not only in their shipping but also in their seeds. They offer a germination guarantee, which means that if any of your seeds fail to germinate for any reason, they will send you replacement seeds. Why would a seedbank do that if they weren’t absolutely confident in their product?
