The 5 Best Cannabis Strains to Grow in Small Spaces

If you want to cultivate cannabis but don’t have much space, we have good news. There are specific marijuana strains that enable you to grow weed in a confined area. Add in the low cost of cultivation, and it’s clear we live in a golden age of cannabis growing.

There are specific marijuana strains that enable you to grow weed in a confined area.

It is paramount to avoid strains that grow tall and bushy. As a result, we have performed research to rule out such plants. This has enabled us to outline five small cannabis strains capable of fitting in a small space.

However, before we begin, let’s look at a few things to consider before cultivating marijuana at home.

What Your Small Space Needs

A small cultivation space doesn’t necessarily mean a low yield, 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. However, 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 keep the grow space clean and protected from the outside environment. You should also be able to drain plants and keep them out of standing water.

Adequate space for growth: Generally, you will need more height than width to keep the lighting from getting too close to the plant. Space becomes tight quickly.

For prospective growers with limited space, 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 loved by many. It offers an uplifting and energizing high, is easy to grow, and doesn’t require a lot of 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 80-140 cm. If you want to keep the plant smaller, you should use low-stress training techniques.

After a flowering time of 9 to 11 weeks, this strain will yield between 600 and 650 g/m². However, 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, it will reach a height of 210 cm. It can offer a rewarding yield of up to 700g/plant.

2. Royal Dwarf

The name of this one says it all. Small, fast, and discreet – that just about sums up the Royal Dwarf strain. Whether you’re a beginner or are 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 remain 40cm tall when trained in the right way. This strain was bred for stealth. You can grow it in wardrobes, boxes, kitchen cupboards, and even computer towers. Small LED lights are ideal in these small spaces to avoid giving off too much heat.

The strain produces an impressive yield, considering its small size. When grown indoors, Royal Dwarf plants produce about 150–200g/m² and usually peak at 70 cm. However, low-stress training can help keep it at a lower height of 40 cm. When grown outdoors, this strain grows to a height of 50–90 cm and produces 30–80g per plant.

Royal Dwarf has a growing cycle of just 8-9 weeks and a flowering time of 6-7 weeks.

3. White Dwarf

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

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 it is an autoflowering plant, you don’t need to vary the lighting to induce flowering. Instead, expose it to 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 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. The strain can be grown almost anywhere – outdoors, indoors, on the windowsill, or in greenhouses.

The main reason for this adaptability is the plant’s short stature. Averaging heights of between 50–60cm when grown indoors, Easy Bud can produce up to 325g/m². It could offer a yield of between 30–80g/plant and grow to a height of 60–110cm when grown outdoors. The plant will be ready to harvest just 8–9 weeks after the seeds are planted in the soil.

5. Critical Kush

Critical Kush is an indica-dominant cross between the famous OG Kush and well-balanced Critical strains. Its average size allows you to grow it in a small, limited space. When grown indoors, the strain reaches 60–100 cm in height. In outdoor environments, it can reach 100–140cm in height.

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

The flowering period lasts around 7 – 8 weeks, and the harvest occurs in late September. The average Critical Kush crop yields 500–550 gr/m2. Its high THC content makes it a great strain for relaxing both the mind and the body. It could also relieve stress and pain.

Final Thoughts on the Best Cannabis Strains to Grow in Small Spaces

You don’t need a lot of space to grow cannabis. However, choosing the right marijuana strain is imperative. There are significantly more diminutive plants available today than just five years ago.

You don’t need a lot of space to grow cannabis. However, choosing the right marijuana strain is imperative.

One of the reasons is the increased usage of Ruderalis genetics in marijuana breeding. You receive lower yields, but such strains grow quickly, which means it is possible to enjoy several harvests a year. Also, autoflowering strains don’t require a grower to force the plant into the blooming phase.
