How To Grow King’s Kush Auto from Seed to Harvest 

King’s Kush Auto by Green House Seeds packs potent, relaxing kush genetics into a tiny, easy autoflower. A cross of King’s Kush x Ruderalis, it is a balanced hybrid at a comfortable 20-21% THC, with a lemony, earthy, piney flavor and a deep body relaxation lifted by a happy, giggly edge. Its standout feature is size: at under a metre tall, it is ideal for small, discreet spaces, and it produces resinous, dense buds fast. 

This is an autoflower, so it flowers on age rather than a change in the light cycle, which keeps the schedule simple. The figures below are Green House breeder values; check your own pack for the exact numbers.

What Makes King’s Kush Auto Worth Growing 

King’s Kush Auto is a compact convenience play with real quality. Its kush heritage delivers a potent, long-lasting, deeply relaxing effect at a solid 20-21% THC, with a pleasant lemony, earthy, piney flavor and resinous, dense buds. The happy, giggly, sedative character makes it a satisfying evening smoke. 

The biggest draw is its size. At around 0.85 m, it is one of the most compact strains you can grow, perfect for small tents, cupboards, balconies, and discreet setups. It flowers fast and is easy to manage, so it suits growers tight on space who still want potent, flavorful buds. The honest trade-off is a modest yield, especially outdoors, so it is about quality and discretion rather than bulk. 

Is King’s Kush Auto Indica or Sativa? 

King’s Kush Auto is a balanced hybrid, listed at 50% indica and 50% sativa, with ruderalis for its autoflower timing. 

That balance shapes the effect: a happy, giggly, talkative lift that settles into a deep, sedative body relaxation, leaning to evening use. The kush genetics give it a compact, sturdy, resinous structure, and the plant stays small and easy to handle, a true space-saver. 

Flowering Time vs Full Grow Time 

Autoflowers confuse a lot of growers on timing, so it is worth being precise. 

• Flowering time: the bloom stage, which for King’s Kush Auto begins on its own around week three or four, often cited as a quick, roughly seven-week bloom. 

• Full grow time (life cycle): 9-10 weeks seed to harvest. This is the number that matters for planning, covering the whole cycle, with flowering happening inside it rather than after a separate long veg. 

The takeaway: plan around the full 9-10 week cycle. Its compact size and fast finish make it easy to fit into tight spaces and quick rotations. 

Does King’s Kush Auto Need a 12/12 Light Cycle? 

No. King’s Kush Auto flowers on age, not day length, so it never needs a 12/12 photoperiod to bloom. 

Indoors you can hold a long schedule like 18/6 or 20/4 from seedling to harvest. That extra daily light feeds the compact buds across the cycle, so keep the long schedule rather than dropping to 12/12, which would only cut light and reduce an already modest yield. 

King’s Kush Auto Grow Timeline, Week by Week 

Treat this as a development pattern, not a fixed schedule, since autos move fast. 

• Weeks 1-2: germination and seedling. The taproot and first leaves establish. Keep water light and conditions stable. 

• Weeks 2-3: vegetative growth. The compact plant builds its small frame and may show preflowers. Begin gentle low stress training if desired. 

• Weeks 3-5: stretch and bud set. Vertical growth slows and flower sites fill in on the small plant. 

• Weeks 5-8: main flower development. Dense, resinous buds build and the lemony-earthy aroma develops. 

• Weeks 9-10: maturation and harvest. Most plants finish here. Judge ripeness by the trichomes, not the day count. 

Choosing Your Setup: Space, Light and Pots 

King’s Kush Auto’s tiny 0.85 m stature is its superpower, fitting into small tents, cupboards, and discreet corners with ease. Because it is so small, heavy training is unnecessary, though a little low stress training can still open the canopy. 

Light still matters for quality and yield, so give it a good source. A full-spectrum LED at 25-35 watts per square foot on an 18-20 hour schedule keeps the small, dense buds resinous. A compact inline fan and carbon filter handle the aroma in a small space. 

Plant straight into the final 2-3 gallon fabric pot, smaller than usual to match the compact plant, and skip transplanting, which autos dislike. Fabric pots air-prune the roots and keep them healthy. 

Germinating and Raising Seedlings 

The paper towel method is the easy, reliable start. Soak the seeds for 12-24 hours, then set them between damp paper towels on a covered plate, kept dark and warm at 70-85°F (21-29°C). A taproot usually shows in two to three days. 

When the taproot reaches about 1-2 cm, plant it root-down a knuckle deep in a light mix and keep the surface moist until the seedling breaks ground. Hold off on nutrients at this stage. New to germination? Our beginner growing guides walk through it step by step. 

The Vegetative Stage and Low Stress Training 

Veg is short on an auto, and on such a small plant there is little to manage. Keep nitrogen available, hold temperatures in the low to mid 70s°F, and if you want to maximize the modest yield, gently tie down the main stem to open the canopy. 

Because an autoflower has little time to recover from stress, and this plant is small to begin with, stick to light low stress training at most, and skip topping entirely. Often the simplest approach, letting this compact plant grow naturally, works just fine. 

Feeding and Watering King’s Kush Auto 

Feed gently. Autos run smaller root systems, and this is a small plant, so start nutrients at about half the label strength or less, and build up cautiously. Use a nitrogen-forward base through early growth, then a bloom formula higher in phosphorus and potassium as flowering sets in, watching the plant respond. 

Water by root-zone moisture, not a timetable. A small plant needs very little water, so take care not to overwater. Let the top layer dry between waterings and water by pot weight. 

Flowering and Knowing When to Harvest 

Flowering begins on its own around week three or four, with a short stretch and the first pistils, then dense, resinous buds build over the following weeks. The lemony, earthy, piney aroma develops, so run a carbon filter indoors. 

As the 9-10 week finish nears, let the plant decide. Check trichomes under a loupe and harvest when most are cloudy with a few amber for the fullest, relaxing effect. After the cut, hang the branches in the dark at about 60°F (15-16°C) and 55-60% humidity for 7-14 days, then cure in jars, burping daily for the first weeks to bring out the flavor. 

Growing Indoors vs Outdoors 

Indoors is the natural home for a plant this small, slipping into tight, discreet spaces. Hold 18/6 or 20/4, give it good light, and it rewards you with resinous, flavorful buds, though the yield is modest by design. 

Outdoors, its per-plant figure is low at around 100 g, reflecting its tiny size, so it suits balcony and patio growers who value discretion over bulk. Being day-neutral, it can be planted through the warm months. Give it full sun, well-draining soil, and airflow around the buds. 

How Tall and How Much? Height and Yield 

Height is the headline, in the best way. King’s Kush Auto stays around 0.85 m, exceptionally compact and ideal for stealth and small spaces, with no height management needed. 

On yield it is modest, reflecting its small size: the outdoor figure is around 100 g per plant, and the indoor figure is not published but will likewise be modest. You grow this one for its potency, flavor, and discretion rather than for heavy weight. 

Best US Climates for King’s Kush Auto 

King’s Kush Auto is flexible thanks to its autoflower timing and tiny size, which make it easy to grow almost anywhere, especially discreetly. It does well in warm, sunny climates like California, the Southwest, and the South, where its fast cycle fits a long season. 

Being day-neutral and compact, it also suits cooler, shorter-season northern states and small balcony or patio setups. In the humid Southeast, keep airflow strong around the dense little buds. For a bigger yielder, browse our full how-to-grow guide library. 

Common Problems When Growing King’s Kush Auto 

A few predictable issues are easy to avoid. 

Overwatering a tiny plant 

A small plant in too big a pot is very easy to overwater. Use a smaller 2-3 gallon pot, water small amounts to root-zone moisture, and let the medium dry between waterings. 

Expecting a big yield 

Its tiny size means a modest harvest, especially outdoors at around 100 g. Grow it for quality and discretion, and run several plants if you want more total weight. 

Overfeeding 

A small plant needs little feed. Start at half strength or less and build up cautiously, watching the leaf tips for nutrient burn. 

Harvesting by the calendar 

The 9-10 week cycle is a reference, not a cutting date. Read the trichomes and flower maturity before you cut, since phenotype and environment shift the timing. 

Making the Most of Your Harvest 

Even from a small plant, do not waste the trim. The resinous sugar leaves make good bubble hash, dry sift, or infused oil that keeps the lemony-earthy character. The stems, roots, and fan leaves compost well and feed your next grow. 

Is King’s Kush Auto Right for You? 

If you want potent, relaxing kush in the smallest, most discreet package possible, yes. Its tiny size, easy grow, fast finish, and quality buds make it ideal for stealth growers, balconies, and tight spaces. If you want a big yield, choose a larger strain or run several of these.

Frequently Asked Questions 

Is King’s Kush Auto indica or sativa? 

King’s Kush Auto is a balanced hybrid, listed at 50% indica and 50% sativa, with ruderalis for its autoflower timing. The effect is a happy, giggly, talkative lift settling into a deep, sedative body relaxation, leaning to evening use. The kush genetics give it a compact, sturdy, resinous structure in a very small plant. 

Does King’s Kush Auto need a 12/12 light cycle? 

No. King’s Kush Auto flowers automatically with age, not day length, so it never needs a 12/12 schedule. Indoors you can hold a long photoperiod like 18/6 or 20/4 from seedling to harvest. That extra daily light feeds the buds across the cycle, so keep the long schedule rather than reducing it. 

How long does King’s Kush Auto take to grow? 

King’s Kush Auto completes its full cycle in 9 to 10 weeks from seed to harvest, with a quick bloom beginning on its own around week three or four. Judge the finish by trichome maturity rather than the day count. Its compact size and fast finish make it easy to fit into tight spaces and quick rotations. 

How much does King’s Kush Auto yield? 

King’s Kush Auto is a modest yielder, reflecting its tiny size: around 100 g per plant outdoors, with the indoor figure unpublished but similarly modest. You grow it for potency, flavor, and discretion rather than bulk. To get more total weight, run several of these compact plants rather than expecting a big harvest from one. 

How tall does King’s Kush Auto get? 

King’s Kush Auto stays around 0.85 m, one of the most compact strains you can grow. That tiny stature is its main appeal, fitting into small tents, cupboards, balconies, and discreet corners with no height management needed. It makes an excellent stealth or space-saving grow for anyone tight on room. 

Can you clone King’s Kush Auto? 

Not usefully. As an autoflower, a cutting keeps the mother’s age, so it tries to flower straight away as a tiny plant and yields almost nothing. If you want more plants, germinate more seeds. Cloning only makes sense with photoperiod strains, not with autoflowers like this one. 

Is King’s Kush Auto good for beginners? 

Yes. Its tiny size, fast 9-10 week cycle, and simple needs make it very beginner-friendly, with little training required. The main things to watch are not overwatering or overfeeding such a small plant. In return you get potent, flavorful, resinous buds from a plant that fits almost anywhere.
