Rhino Ryder Auto by FastBuds is a compact, resin-rich indica autoflower built for potent, relaxing flower and excellent hash. A cross of Medicine Man with ruderalis, it carries a solid 20-21% THC, earthy, peppery, and fruity flavors, and a deeply relaxing effect. It stays small, produces dense, resilient buds, and finishes its whole cycle in 9-10 weeks from seed, which makes it a rewarding, low-fuss grow for relaxation and extraction alike.
Because it is an autoflower, it flowers on its own with age instead of waiting for a change in the light cycle. That makes it fast and simple, but it also changes how you light, train, and time the grow, as explained below.

What Makes Rhino Ryder Auto Worth Growing
Rhino Ryder Auto is a quiet overachiever. Its Medicine Man heritage gives it a classic earthy, peppery, fruity profile and a deeply relaxing effect at a solid 20-21% THC. The buds come out dense and heavily coated in resin, which makes it a standout choice for hash and other extracts as well as flower.
It is also easy and productive. The whole cycle runs about 9-10 weeks from seed, it stays a compact 1.1 m, and it still yields a high 400-500 g/m² indoors. Its resilient, sturdy structure forgives beginner mistakes, so it rewards both new growers and experienced ones looking for a reliable, resin-rich autoflower.
Is Rhino Ryder Auto Indica or Sativa?
Rhino Ryder Auto is indica dominant, listed at 60% indica and 40% sativa, from crossing Medicine Man with ruderalis.
That indica lean shows in both the plant and the effect. It grows short, bushy, and compact with sturdy, resilient branches, ideal for small spaces, and the high is deeply relaxing with a strong body presence, best suited to evening use. The resin-heavy buds reflect its potent, hash-friendly genetics.
Flowering Time vs Full Grow Time
For an autoflower, this works differently than for a photoperiod, and understanding it is the key to timing the grow.
- Full life cycle: around 9-10 weeks from seed to harvest. This is the number that matters most for an auto, since the plant moves through veg and into flower automatically.
- Flowering portion: flowering begins on its own at roughly 3-4 weeks of age, with no change to the light needed, and runs through to the harvest inside that total window.
The practical takeaway: you cannot extend the veg stage to grow a bigger plant the way you can with a photoperiod. What you plant is roughly what you get, so the early weeks matter. Keep seedlings healthy and stress-free, because the plant is on a fixed clock.
Does Rhino Ryder Auto Need a 12/12 Light Cycle?
No. This is the key difference from photoperiod strains. As an autoflower, Rhino Ryder Auto does not need a 12/12 light cycle to flower. It starts flowering on its own with age, regardless of the light schedule.
Most growers run 18/6 (18 hours on, 6 off) for the entire life cycle, from seed to harvest. Some use 20/4 for a little more light and growth. There is no flip and no separate flowering schedule. Outdoors it flowers on age too, so in a warm, long season you can fit more than one crop in a year.
Rhino Ryder Auto Grow Timeline, Week by Week
With an auto, the timeline is on a fixed clock, so these stages happen on schedule rather than when you decide.
- Weeks 1-2: germination and seedling. The taproot and first true leaves establish. Keep things gentle and stress-free, since the clock is already running.
- Weeks 3-4: vegetative growth. Fast, bushy growth under 18/6. Begin gentle low stress training now if you train at all.
- Weeks 4-5: pre-flower and stretch. The plant starts flowering on its own and sets its structure.
- Weeks 5-9: flowering. Dense, resinous buds form and fill out, and the earthy, peppery aroma develops.
- Weeks 9-10: ripening and harvest. Judge by trichomes, not just the calendar.
Choosing Your Setup: Space, Light and Pots
Rhino Ryder Auto stays compact at around 1.1 m, so it fits easily into small tents and tight spaces. Give it strong, consistent light on an 18/6 schedule for the whole cycle to back the high THC and resin production. A full-spectrum LED at 30-40 watts per square foot is plenty.
The single most important setup choice for an auto is the pot. Plant in the final container from the start, ideally a 3-5 gallon fabric pot, and do not transplant. Autos dislike root disturbance, and because they are on a fixed clock they have no time to recover from transplant stress. Fabric pots also improve airflow and help prevent overwatering.
Germinating and Raising Seedlings
The paper towel method is the simple, reliable start. Soak the seeds for 12-24 hours, then place them between damp paper towels on a covered plate, kept dark and warm at 70-85°F (21-29°C). A taproot usually appears within two to three days.
When the taproot reaches about 1-2 cm, plant it root-down a knuckle deep directly into its final pot and keep the surface moist until the seedling emerges. Hold off on nutrients at this stage. With an auto, a healthy, stress-free start is especially important because the plant is already on its clock. New to growing? Our beginner growing guides cover germination step by step.
The Vegetative Stage and Low Stress Training
Veg is short and automatic with this strain, so the goal is to support fast, healthy growth, not to extend it. Keep it under 18/6 with a light feed and let the compact, bushy frame build quickly.
Because the plant is on a fixed clock, stick to low stress training (LST) and skip high-stress techniques. Gently tie down the main stem and branches to open the canopy and expose more bud sites to light, which suits its naturally bushy shape. Avoid topping and other heavy training, which an autoflower often cannot recover from in time. For the same reason, cloning is not practical with autos, so each plant is a single, seed-to-harvest grow. Train early and gently, during the first few weeks only.
Feeding and Watering Rhino Ryder Auto
Autos are light feeders, so go easy. Use a gentle, nitrogen-forward feed at reduced strength through the short veg, then switch to a bloom formula higher in phosphorus and potassium as flowering begins. Start at roughly half the dose you would give a photoperiod and increase only if the plant asks for it. Overfeeding is the most common mistake with autos.
Water by root-zone moisture, not a timetable. Let the top inch or two of medium dry between waterings, then water thoroughly until a little drains. Fabric pots and this water-to-weight habit keep the roots healthy and prevent overwatering, which small-rooted autos are sensitive to.
Flowering and Knowing When to Harvest
Flowering begins on its own at around 3-4 weeks of age. Dense, resinous buds form and fill out through the back half of the cycle, and the earthy, peppery, fruity aroma develops, so keep air moving and run a carbon filter indoors.
Let ripeness, not just the calendar, decide the harvest. Check the trichomes under a loupe and cut when most are cloudy with a few turning amber for the fullest effect, and when making hash a slightly later, resin-rich finish can help. After harvest, hang the branches in the dark at about 60°F (15-16°C) and 55-60% humidity for 7-14 days, then cure in sealed jars, burping daily for the first couple of weeks to protect the flavor.
Growing Indoors vs Outdoors
Indoors, Rhino Ryder Auto is easy and fast. Run 18/6 for the whole cycle, keep it in its final fabric pot, and the compact size and high 400-500 g/m² yield make it an excellent tent strain with a quick turnaround.
Outdoors, it is a resilient, flexible producer that finishes fast. Because autos flower on age, not on the season, you are not tied to a single planting window, and in a warm climate you can run more than one crop per year. Its sturdy structure handles the elements well. Give it full sun, a light airy soil, and protection from constant wet.
How Tall and How Much? Height and Yield
Height is easy to plan for. Rhino Ryder Auto stays compact at around 1.1 m, so it fits comfortably in most tents and does not need aggressive height control.
On yield it is a strong producer, listed as high at around 400-500 g/m² indoors, excellent for such a small, fast plant. Strong consistent light, gentle LST to open its bushy canopy, the right final pot, and a careful feed are what turn that potential into real weight of dense, resin-coated flower.
Best US Climates for Rhino Ryder Auto
As a fast, compact, resilient autoflower, Rhino Ryder Auto suits a wide range of US climates. Its age-based flowering means it is not tied to the season, so growers in cooler or shorter-season states can still get a full outdoor crop, and warm-climate growers in California and the Southwest can run multiple cycles per year.
It thrives indoors anywhere thanks to its small size. Its sturdy, resilient build handles variable weather better than many strains. In the humid Southeast, keep airflow strong around the dense buds to prevent rot. For more options, browse our full how-to-grow guide library.
Common Problems When Growing Rhino Ryder Auto
A few predictable, auto-specific issues are easy to head off.
Transplant shock
Autos hate root disturbance and have no time to recover on their fixed clock. Plant in the final pot from the start and never transplant.
Overfeeding
Autos are light feeders. Start at about half strength and build up only if needed, watching the leaf tips for nutrient burn.
Bud rot in dense indica buds
The dense, resinous buds can trap moisture. Keep humidity moderate in late flower and air moving through the bushy canopy.
High-stress training
Topping or heavy defoliation can stunt an auto permanently. Stick to gentle low stress training in the first few weeks.
Making the Most of Your Harvest
Rhino Ryder Auto is a hash lover’s strain, so do not waste the trim. The resin-rich sugar leaves make excellent bubble hash, dry sift, or rosin that captures its earthy, spicy character. The stems, roots, and fan leaves compost well and feed your next grow.
Is Rhino Ryder Auto Right for You?
If you want a compact, easy, resin-rich plant for deep relaxation and great hash, yes. Its fast 9-10 week cycle, small size, solid potency, and heavy resin make it a reliable all-rounder for beginners and extract fans alike. If you want a tall photoperiod to shape with topping, or a pure daytime sativa, look elsewhere. Browse our full how-to-grow guide library for more.
