Looking to grow the smallest weed plants in tight corners without compromising THC levels? The best cannabis seeds for you are listed below! If you only have a small space for growing cannabis, which strains should you choose? We've put together this list of some of the best.
Top 5 strains to grow in small spaces
Lots of people grow cannabis very successfully with small indoor grow rooms. Although many indoor cannabis growers use tents that are around 1.8m – 2m tall, you can also grow cannabis with as little as a metre of vertical grow space.
So long as you select compact strains that are proven to grow in small spaces you should get some great results. If you’re looking to grow the shortest, smallest weed plants then read on for some top tips and expert advice. Growing small cannabis plants doesn’t mean that you need to compromise on quality. With well-chosen cannabis seeds you can expect high quality, THC rich harvests even from small grow spaces!
Average height of cannabis and smallest weed plants
Average plant heights vary according to the types of genetics in the cannabis seed. The smallest weed plants are probably found by growing compact indica autoflowering seeds. These can be around 50cm in height. If combined with an LED bar light, you could probably just about manage in a grow room that is 1m tall.
Short cannabis strains can also be grown from photoperiod feminised seeds. In order to get small and compact results short indica strains (or indica leaning hybrids) are often preferred. Short sativa strains can be difficult to find unless you are prepared to top them, and grow them in small containers.
Autoflowering cannabis seeds for low height grow rooms
Most indoor growers that buy autoflowering cannabis seeds tend to find that the plants reach around (or below) a metre tall. Some stretchier sativa autoflowering seeds may reach a little taller and indica autoflower seeds may remain shorter, perhaps around 50-75cm (or even shorter in some cases). Some of the best short autoflower strains are those that have dominant Kush or indica genetics.
Photoperiod feminised cannabis seeds for growing in small spaces
Photoperiod feminised cannabis seeds can show quite a variation in plant heights. Buy some Haze seeds, or a jungle sativa like Desfrán and you may find that the plants will fill all available space. In unrestricted conditions, many sativa seeds will comfortably reach 1.5 m tall, or much more. If you’re looking to grow short height strains from feminised seeds then indica or indica-leaning hybrid strains are the best choices. These can often stay below a metre in height.
If you top (or ‘FIM’) your cannabis plants while they are young you can produce short bushy cannabis plants. This is one technique to produce the smallest marijuana plants. But other techniques include using smaller plant containers, perhaps 5 litre or so, to restrict the final plant size.
Best 5 cannabis seeds for the smallest grow spaces
The following selection of autoflower seeds and photoperiod feminised seeds have been recommended for their reliably compact and consistent small growth structure which makes them ideal for the indoor grower with limited grow space. If you have limited space and want to grow a small weed plant, these are out top 5 recommendations. All of them have excellent vape/smoke quality too!
Auto Banana Blaze: XL yields, most plants around 75cm in height
Auto Banana Blaze is a top quality indica autoflower strain from the cannabis cup winning Dutch Passion Afghani Kush cannabis seed collection. Short marijuana strains don’t get much tastier and heavy yielding than this. Auto Banana Blaze seeds grow with a short, compact Christmas tree structure. The aroma is creamy, sweet, fruity and tropical. This mini weed plant takes around 12 weeks to grow from seed to harvest.
The yields are notably heavy. Just because you are growing a short cannabis plant doesn’t mean that you have to compromise on yield. With a well optimised grow room (and especially with a good quality LED grow light) you definitely don’t need to compromise on harvest quantity. In fact, short height cannabis strains are often preferred by many legal, licensed cannabis producers. That’s because small cannabis plants are ideal for stacked, multi-level grow operations where 2 (or even 3) levels of plants are grown with LED bar grow lights. This is a recipe for very high levels of productivity.
Auto Banana Blaze is recommended for anyone needing a solid, short high yield strain that delivers hard dense buds with a powerful indica effect. With a delicious sweet banana flavour and an uncomplicated growing pattern, this is an easy strain to grow.
Auto Banana Blaze seeds are a proud member of Dutch Passion’s Very High THC seed collection. You won’t be disappointed with the potency of THC rich buds. These pack a real punch with a strong, long lasting high and powerful body effects. Perfect for growing weed in small spaces!
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.
Avoiding strains that grow tall and bushy is of paramount importance. 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 properly.
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 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 the plant smaller, you should use low-stress training techniques.
After a flowering time of 9 – 11 weeks, this strain will yield between 600–650g/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, 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 the small size. When grown indoors, Royal Dwarf plants produce about 150–200g/m² and usually peak at the height of 70 cm. However, low-stress training can help keep it at a smaller 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 and 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 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 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. It is 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 short stature of the plant. 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 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 strains. The average size of the plant allows you to grow it in a small, limited space. When grown indoors, the strain reaches 60–100 cm. 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.
