The 5 Best Cannabis Strains to Grow in Small Spaces

For all those cannabis enthusiasts who don’t have much space and are looking to grow their own cannabis strains, we have some good news for you. You don’t need a lot of space to grow cannabis – well, certain strains.

As cannabis and its cultivation is becoming more popular than ever before, we see an increasing number of people wanting to grow their own cannabis strains. The problem is that most beginner growers don’t have the knowledge, experience, tools, equipment, or space to go for a large-scale grow operation for these plants.

Some cannabis plants tend to grow tall and bushy and therefore need a lot of space. Meanwhile, other plants don’t necessarily grow tall but would require a large amount of space for nutrients. But, there are certain strains that have been specifically bred for small indoor spaces.

What Your Small Space Needs

A small grow space doesn’t necessarily mean small returns, but it’s important to grow as efficiently as possible. Your grow space can be as small as a 2’ x 2’ x 4’ grow tent or as large as a warehouse, but each space should meet the following requirements:

  • Ventilation: Plants require fresh air. A constant change of air is important to keep them healthy and vibrant. Depending on the environment, you may need a heater or AC unit to regulate the climate.
  • Sterilization: You must be able to keep the grow space clean and protected from the outside environment. You should also be able to properly drain plants and keep them out of standing water.
  • Adequate space for growth: Generally, you will need more height than width, to keep lights off the plant. Space becomes tight quickly.

For those farmers with limited space for growing, here is a list of the best cannabis strains to grow.

1. Amnesia Haze

Created from old Haze genetics, Amnesia Haze is a high-yielding, powerful sativa that is loved by many. It offers an uplifting and energizing high, is easy to grow, and doesn’t require a wide outdoor space. Since the strain is available as an auto-flowering plant, it thrives well indoors with minimal sunlight and space.

Amnesia Haze grows to medium height in both indoor and outdoor environments. It’s a highly productive strain and brings about rewarding yields, even when grown in relatively small areas. Grown indoors, the plant reaches heights of between 80 – 140 cm. If you want to keep her smaller, you should use techniques like low-stress training to tame her.

After a flowering time of 9 – 11 weeks, this strain will provide a yield of between 600–650g/m². Waiting a few extra weeks compared to other strains doesn’t offer many more benefits regarding flavors, potency, and effects.

When cultivated outdoors, the strain prefers a mild climate. Grown in large containers or garden beds, she will reach a height of 210 cm and bring about a rewarding yield of up to 700g/plant.

2. Royal Dwarf

The name of this one says it all. Small, fast, discreet – that just about sums up the Royal Dwarf strain. Whether you’re a beginner grower or are simply looking for a fast-growing cycle, this strain hits the mark. Royal Dwarf is also ideal for growers with limited space, and those looking to keep things discreet.

Royal Dwarf is a miniature cannabis specimen that can stay at tiny sizes of 40 cm tall when trained in the right way. This strain was bred for stealth. She can be easily grown in wardrobes, boxes, kitchen cupboards, and even computer towers. Small LED lights can be used in these small spaces to avoid giving off too much heat.

The strain produces an impressive yield, considering the small size. When grown indoors, plants produce about 150–200g/m² and usually peak at a height of 70 cm. However, low-stress training can be used to help keep her at a smaller height of 40 cm. When grown outdoors, she will grow to a height of 50 – 90 cm and produce yields of 30–80g per plant.

Royal Dwarf has a growing cycle of just 8-9 weeks and a flowering time of 6-7 weeks. So you won’t have to wait long to taste these buds.

3. White Dwarf

The White Dwarf strain is a short-growing and autoflowering plant that is characterized by its small and discrete size. It’s ideal for small spaces and is ready for harvest in just two months. The strain is an indica-dominant hybrid, and its effects do a good job of reflecting this.

White Dwarf is often recommended to newbie growers who are in search of a low maintenance plant. The seeds produce short bushy plants that grow to a height of 30 – 50 cm. The leaves are greenish, and the buds are dense and on the small side.

When grown indoors, White Dwarf does best in rich compost in individual pots. Since its autoflowering, you don’t need to vary the lighting to induce flowering. Simply leave it under 20 hours of light each day. The flowering time is 5 – 6 weeks, and the plants are ready to harvest in just 8 weeks. You can expect a yield of 25 to 40 grams for each plant.

4. Easy Bud

Easy Bud is perfect for beginner growers and even better for anyone wanting to start out low-key, and garner as little attention as possible. It’s a superb indica-dominant strain that has many similarities to Royal Dwarf. The plant goes mostly unnoticed wherever it’s grown, reaching an average height of 50 cm.

This means that it’s possible to grow Easy Bud in empty cupboards, down-low attic spaces, and hidden corners of the garden. In fact, the strain can be grown almost anywhere – outdoors, indoors, on the windowsill, in greenhouses, everywhere!

The main reason for this adaptability is the short stature of the plant. Averaging heights of between 50 – 60 cm when grown indoors, you can expect yields of up to 325g/m². Easy bud plants grown outdoors produce yields of between 30–80g/plant and grow to a height of 60 – 110cm. The plant will be ready to harvest after just 8 – 9 weeks after putting the seeds into the soil.

5. Critical Kush

Critical Kush is an indica-dominant cross between the famous OG Kush and well-balanced Critical. The average size of the plant allows you to grow her in a small, limited space. When grown indoors, the strain reaches 60 – 100 cm, and in outdoor environments, it gets to about 100 – 140 cm in height.

Despite its compact structure, Critical Kush produces decent yields thanks to its high number of flowers that turn into tasty buds.

The flowering period comes in 7 – 8 weeks, and the harvest occurs in late September. The average crop yields 500 – 550 gr/m2. Its high THC content makes it a great strain for relaxing both the mind and the body, as well as relieving stress and pain.
