Depending on your cannabis growing goals and your location, choosing a marijuana plant based on its growing conditions makes sense. For example, you would want to keep a delicate plant indoors to prevent it from developing rot or to keep pests away. But, if it’s a tall and potent smelling plant, you’ll likely find growing it outdoors a better choice.
In the content below, we’ll look at five strains ideal for growing indoors. Then, we’ll discuss five strains that make sense to grow outdoors. After your research, you can make the best choice for you based on the weed garden you want to create.
Top 5 Cannabis Strains for Your Indoor Garden
If you live in a place with inclement weather, having an indoor cannabis garden makes the most sense. Or, if you live in an urban area, keeping your plants private could be ideal. After careful consideration, in our opinion, these are the top 5 strains to grow inside.
Girl Scout Cookies
One of the most potent strains of cannabis, Girl Scout Cookies is an indica-dominant hybrid. Indoors, the plant produces flowers in nine to 10 weeks. While the yield isn’t the largest, the high is worth the effort.
Girl Scout Cookies will give you a short to medium height plant with sturdy branches. Plus, growing indoors gives you the option to drop the temperature. A cooler temp with these plants will provide you with a purple color and rich density buds with crystallization.
Girl Scout Cookies is very resistant to mildew and pests. This plant will grow well in hydroponics or soil. Most importantly, you’ll want a stress-free space for your plant to branch out. Unless you live in a Mediterranean climate, growing Girl Scout Cookies indoors is your best bet.
Pure indica, Afghan Kush loves a climate that mimics a European summer. The plant only takes around seven to eight weeks to flower, and you can expect a yield of about 16 ounces per 10 square feet when growing indoors. Also, Afghan Kush is highly resistant to molds, parasites, and pests. You can expect this to be easy to grow in soil or a hydroponic system.
Gorilla Glue #4
Gorilla Glue #4 can yield about 18 ounces for 10 square feet when grown indoors, and this strain only takes about eight to nine weeks to flower. The plants can grow in a warm sunny outside garden, but you can reap the benefits of a dank indoor harvest without risking them in outdoor conditions.
White Widow is a sativa-dominant hybrid that is easy to grow and is a top pick for beginners. The plant reaches a medium height and can yield around 18 ounces per 10 square feet when grown indoors.
White Widow flowers in eight to nine weeks. While you can grow this plant outside, we recommend that you grow White Widow indoors in a controlled setting. You can grow in either soil or hydro, but a hydroponic setup will surpass your harvesting expectations.
Kandy Kush OG
Kandy Kush OG has a moderate to high yield with a flowering time between 65 to 75 days. The plant is mold-resistant and grows well in cooler climates. It’s a splendid blend of OG Kush and Trainwreck. When growing indoors, it’s best to use the Screen of Green (SCROG) method.
Top 5 Cannabis Strains for Outdoor Growing
There are many reasons for growing cannabis outside. It’s more environmentally friendly, you can yield more buds, it’s much cheaper, and outdoor buds develop a distinct flavor. When looking to grow outdoors, you likely want a large plant that gives you a maximum yield. Below you’ll find the top 5 marijuana plants to grow outside.
If you’re looking to grow a tree-sized cannabis plant, Northern Lights can grow more than 6.5 feet outdoors. The plant will thrive most in a sunny and warm environment. Like many strains, the Mediterranean climate is best for this plant to flourish.
Northern Lights is a hardy, pest-resistant plant that is pretty easy to grow. The strain takes about seven to nine weeks to flower.
Swazi Gold is pure sativa that may take 12 to 14 weeks to flower and has the ability to grow quite big. Aside from the high level of attention necessary to grow Swazi Gold, the sheer number of buds you can produce is worth all the love and effort. You can expect more than 25 ounces per plant!
You need to grow Durban Poison outdoors if you want your plant to reach its full potential. The warm sunlight is ideal for your plant, and the being outside gives the plant room to spread its branches. You can expect your plant to tower to more than seven feet tall.
Durban Poison is resistant to pests and common molds.
Perfect for cultivating outside, you can expect an impressive yield with little effort. Blue Dream is a true dream for growers in a subtropical or Mediterranean climate. You can expect more than 20 ounces per plant, and your plant could grow higher than 13 feet tall. Also, Blue Dream may be one of the easiest strains to grow outdoors, especially for novice growers.
Alaskan Thunder Fuck
Let’s face it, Alaskan Thunder Fuck is a pretty awesome strain name. Nothing will compare to growing Alaskan Thunder Fuck outside. The plant does well in a cooler northern climate and can produce a massive yield. When grown outdoors, you can get more than 30 ounces per plant. While this is a cold-weather strain, you’ll still want plenty of sun exposure and food to encourage healthy growth.
Also, if you grow this plant in a trench, it will help keep the roots warm. Flowering time is about nine to 10 weeks.
Keep in mind, you can grow any indoor strain outdoors, and you can grow outdoor strains indoors. You’ll want to make sure you have the right spacing, lighting, food, and watering needs for the plant you’ve chosen. With the internet available at our fingertips, you have the resources and information to try anything you want. Whether you’re an expert or novice grower, there is always something to learn about maximizing your yield.
Top 6 weed strains to grow indoors
New growers searching for the best strains to grow indoors need to look no further. Check out the top weed strains to grow inside.
By subject matter expert and editor: Pat Goggins
Indoor weed is famous for its high quality, and you can grow it anytime of year if you’ve got the right space for it. Grow tents and grow lights are cheap and easy to use, and you’ll cover the initial cost of investment quickly.
Which strains should you grow?
Some strains grow better in an indoor environment, while others do better outdoors. Indoor growers typically go for short, stout plants because they take up less space, which can be limited indoors.
Strains that finish quicker—meaning, a short flowering time—are also desired, to save money on your electricity bill. Indica strains typically fit this bill, while sativas and hybrids usually grow bigger and take longer to finish, but it really depends on the strain.
If you love a certain strain that takes 11 weeks to flower, go for it, but whichever strain you choose, check the breeder or seed bank’s information on it to get a sense of how it’ll grow.
Understanding autoflower strains and feminized seeds
Autoflower strains are a great option for growing indoors as they can go from seed to harvest in as little as three months. But, beware: the final buds might not be that potent.
Feminized seeds are also useful because they ensure every plant is a bud-producing female, which saves space in your indoor grow because you won’t have to grow males and get rid of them.
A lot of common, classic strains come in autoflower and feminized varieties.
With thousands of strains to choose from, here are six of our favorites that are great to grow indoors.
(Elysse Feigenblatt for Leafly)
Some people roll their eyes when you mention the popular strain, Blue Dream, but it truly is a dream to grow. This classic hybrid of Haze and Blueberry grows to a moderate size, has an average flowering time, and doesn’t need much attention indoors.

Bruce Banner is a great old-school strain that flowers quickly and packs a hefty, euphoric punch.
