Which cannabis strains stay short? (Best strains for small spaces)
Each cannabis plant grows a little different. Some tend to grow tall and thin, while others stay short and bush out. Genetics affects everything from yield, potency, color, and smell of buds.
Many autoflowering strains tend to stay short, especially when grown in small pots.
But if you’re growing in a short space (for example in a stealth setup or if height is limited), you can save yourself a bunch of headaches by starting with a strain that tends to stay short. That gives one less thing for you to worry about.
Auto-flowering strains that stay short
– Classic effects that are relaxing but not overwhelming, easy to grow, and smells amazing – Purple buds, fast finishing, easy to grow, average-to-high potency – Fuel or gas smell, high potency, “uplifting” and “creative” psychological effects are excellent during the day – Resistant to problems, buds sparkle, very high potency – Distinctly Californian sweet smell, high potency, “body high” and “heavy” effects are a great way to end a long day
THC Bomb Auto plants tend to stay short and produce above-average potency and yields
Photoperiod strains that stay short
– Beautiful sparkly buds, bubblegum scent, good yields, high potency – Exceptional sweet smell and taste, easy to grow, very high potency (Royal Queen version) – Great yields, easy-going, quick time to harvest, high potency but not overwhelming effects – Easy to grow, quick to harvest, old school classic 90s effects with an extra kick – Buds take on purple tints, excellent smell, potent and long-lasting effects (King Tut) – Relatively low smell (which may be better for stealth), extra high potency
Tutankhamon plants don’t have a strong smell, which may be a good thing in a stealth setup. Buds get so dense they may need to be held up with plant yo-yos and the potency/effects are legendary.
Note: In order to start making buds, photoperiod strains need 12-hour dark periods (12/12 light schedule). Long nights make them “think” winter is coming and they start flowering.
are a great choice for small spaces because they tend to stay small plants should be given 12/12 within 2-3 weeks of germination so they start flowering as soon as possible
- Look at strain details and try to find strains that are listed as staying short
- Ask the breeder if you have any questions. Most breeders are happy to discuss their strains with you (try their social media account or look for contact information on their official website)
5 Big Tips to Growing Cannabis Plants in Short Spaces
I shared some great cannabis strains that are less likely to get out of control, but here are 5 more tips to help ensure you get the best result growing tiny plants in your cannabis “microgrowery”.
- Use smaller pots – Restricting the root size helps keep plants shorter (but only to an extent). Some growers even grow in solo cups. I’ve found 6″ square hard-sided pots (bonsai flower pots) are excellent at helping keep plants short, but are much more stable than cups. Their square shape lets you fit multiple plants close together. Any pot under 1-gallon size should keep plant size from getting out of control as long as you’re growing a short strain.
- Use hard-sided plant containers – Plants tend to stay smaller in hard-sided plant containers vs the same size fabric or air pot (the extra oxygen makes plants grow faster and plants tend to get bigger).
I like 6″ square hard-sided pots (blue pots in this picture) when you’re trying to keep plants as small as possible. They’re small enough to restrict plant size, but plants can get big enough to produce a few ounces. I also have a few autoflowering plants in plastic cups in this picture.
Using bigger pots and/or fabric pots (these are 3-gallon fabric pots in a small 2’x2’x4 grow tent) contributes to plants growing out of control
Bend stems to keep plants shorter (“plant training”)
- If any stem starts getting too tall, gently bend it over and tie it down in place with plant twist ties
- Learn supercropping technique to bend tough branches that seem like they’ll break
- This splits the main stem into two separate branches so it’s easier to spread out a too-tall plant
- Also tends to help keep auto-flowering plants short because it can trigger them to start flowering earlier (learn how to top an autoflowering strain)
Use simple plant training techniques to bend stems over as they grow and force plants to grow the exact size and shape you want. This cannabis plant produced several ounces yet was only a little over 1′ tall (1/3m) at harvest. For reference, this grow tent is 3′ (1m) tall and the light was an HLG 100 4000k LED grow light.
Ocassionally bend over the tallest stems and tie them down flat with plant twist tie. Get creative to attach the other side of the twisty tie to your plant pot (examples: binder clips, safety pin, poke a hole through pot, wrap tie around the pot lip, etc.)
If you keep bending and tying plant down as it grows…
You’ll end up with a wide, flat plant like this
This forces plants to stay short. Here’s that plant just before harvest. Quite a bit of weed for 100W of LEDs in a 3′ (1m) tall grow tent
Fewer plants are better for short spaces
- It’s easier to control the height of plants when you grow only 1 or 2 plants at a time. You have less to worry about
- If you do plan on growing multiple plants, use pots that are 1 gallon or smaller
It’s easier to care for one plant when you’re worried about height because it gives you more flexibility
You can grow multiple plants but make sure to give them small pots and stay on top of plant training. If one plant starts going crazy, you may have to remove that one and continue with the orderly plants.
- Use blue or vegetative spectrum grow lights (can be used from seed to harvest and help keep plants shorter) – HLG 4000k are a great choice.
- Avoid red or “bloom” grow lights in the vegetative stage (these tend to make plants grow more tall and stretchy)
- Find a grow light that can be kept close to your plant, to maximize the height available to you.
- Recommended grow lights that can be kept under 12″ away:
(I’ve used the 4000k version from seed to harvest with great results) (I’ve found plants can get within inches without getting burned)
- A 150W HPS (I like the 150W Sunburst model) may be a better choice for a cool grow room because plants grow slowly under LEDs if it’s under 78°F/26° with the lights on. Plants light it relatively warm under LEDs. On the other hand, plants actually prefer cooler temperatures under a HID lights like a Metal Halide or HPS grow light. Some growers don’t want to pay to heat a cool grow room. A 150W HPS can be kept only 10-12″ away from the tops of plants as long as the temperature stays under 80°F/27°C. Normally I recommend staying away from HPS lights in the vegetative stage because they have a yellow/red spectrum which tends to cause stretching. However, I’ve found plants seem to stay short enough when you’re using the smaller HPS lights, likely because the light is so intense that it reaches basically to the bottom of the plant. Plus you can always use bending and tying down for any stretchy branches. I just recommend avoiding using LEDs is the grow space is cool.
The HLG 100 (4000k version) helps plants stay short and can be used from seed to harvest
If you want to grow plants without smell, you need to get a grow tent + fan + carbon filter. This combo prevents smells from leaking out of the garden (weed can get smelly). As an added bonus, this helps move air around the plants which prevents hot spots from the light, vents out any extra heat, and gives fresh air to the plants, resulting in faster growth and helps prevent mold when buds get fat).
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.
