From Seed to a Fairytale Finish: The Full Grow-Along
C99 is famously resilient and a vigorous grower, making it a fantastic choice for cultivators of all experience levels. Here’s everything you need to know.
Germination: The First Spark of Magic
Every great plant starts with a single healthy seed. The paper towel method is my trusted technique.
- Soak: Give your seeds a 12 to 24-hour soak in a glass of room-temperature water.
- Wrap: Place the hydrated seeds between two paper towels that are damp, but not dripping wet.
- Keep it Warm & Dark: Put your paper towel setup inside a Ziploc bag or between two plates.
- Sprout!: In 3 to 7 days, a tiny white taproot will emerge. Game on! Carefully plant it about a half-inch deep in your starter pot, with the root pointing down.
Common Mistake to Avoid: Being too rough. That new little taproot is the most fragile part of the plant’s life. Use tweezers and a gentle touch when moving it to its new home.
A Quick Word on “Regular” Seeds
Regular seeds are cannabis in its most natural form, which means they will grow into both male and female plants.
- For Bud-Only Growers: Your mission is to identify the male plants as soon as they show their sex (usually a week or two into flowering) and remove them. This prevents them from pollinating your females and making them produce seeds instead of potent buds.
- For the Breeders & Innovators: This is where the fun begins! The male plants produce the pollen you need to cross with your best female plants. This is how you create your own unique hybrids and innovate within our growing community!
The Vegetative Stage: Building a Strong Foundation
During the veg stage, your C99 is focused on building a strong, bushy structure to support all those future dense, heavy buds.
- Light Cycle: You need long “days” to promote strong vegetative growth. An 18/6 light cycle (18 hours of light, 6 of darkness) is the gold standard.
- Nutrient Needs: Your plant needs a balanced “grow” fertilizer with plenty of Nitrogen (N) during this phase to fuel all that leafy development.
- Train for Bigger Yields: This plant responds incredibly well to training. Techniques like Topping or Low-Stress Training (LST) will open up the canopy, allow more light to reach the lower branches, and dramatically increase your final yield.
The Flowering Stage: A surprisingly fast Finish!
This is where the magic really happens. To trigger flowering, you MUST switch your lights to a strict 12/12 cycle (12 hours of light, 12 hours of absolute darkness).
The flowering time for C99 is famously fast for a sativa, typically 7-9 weeks. During this phase, the plant will stretch a bit, then focus its energy on developing incredibly dense and resinous buds that reek of sweet pineapple and citrus.
When you flip your lights, switch to a “bloom” fertilizer that is higher in Phosphorus (P) and Potassium (K) to support this amazing flower production.
Common Mistake to Avoid: High Humidity. Those dense C99 buds are a magnet for mold if your humidity is too high. It is CRITICAL to keep your humidity levels lower (around 40-50%) and ensure good airflow during the flowering stage.
Promos & Deals
Indoor vs. Outdoor: Choosing Your Grow Environment
This sativa-dominant hybrid is adaptable, but a controlled environment will give you the best results.
Growing Indoors Its surprisingly compact size for a sativa makes it a champion for indoor growers.
- Height: This is a very manageable plant for a sativa. Expect a final height between 3 to 5 feet (100-150 cm). It’s perfect for most grow tents, especially with training.
- Odor Control: The sweet, tropical aroma is amazing, but it’s strong. A good carbon filter is essential for a discreet indoor grow.
Growing Outdoors If you have the right climate, you can cultivate a beautiful outdoor C99.
- Height Potential: Unrestrained outdoors, this plant can stretch up to 6.5 feet (2 meters) or more.
Best U.S. Cities and Climates: This strain loves a warm, sunny, temperate climate.
- California (San Francisco, Santa Cruz): The Mediterranean climate is perfect for this strain to thrive.
- Oregon (Portland): The temperate climate and long summer days will fuel massive growth.
- North Carolina (Asheville): The long, warm growing season is great, but be vigilant about humidity.
Pro-Level Playbook: Cloning and Powerful Extractions
Cloning: Keep the Legend Alive
Find a specific C99 plant with that perfect potent effect? Clone her!
- Select & Snip: Take a healthy 4-6 inch cutting from a lower branch of a mother plant in her vegetative stage. Use a sterile razor for a clean cut.
- Hormone Dip: Immediately dip the cut end in a rooting hormone to inspire vigorous root growth.
- Plant It: Place the cutting into a moist starter cube like Rockwool.
- Keep It Humid: Cover your new clones with a humidity dome to keep them from wilting.
- A New Generation: In about two weeks, you’ll have a new plant that is a perfect genetic copy of your prized mother!
What to Do With Your Trim? Make a Masterpiece!
A sustainable grower uses the whole plant! The frosty trim from your C99 is a goldmine of flavor.
This is THE perfect strain for making high-quality, terpene-rich extracts like live resin, hash, or BHO (Butane Hash Oil). These methods capture the fresh, volatile pineapple and citrus terpenes that define the strain’s amazing aroma and taste.
The Grand Finale: Harvest, Dry & Cure
You’ve made it! Get a jeweler’s loupe and look at the trichomes. When they have changed from clear to mostly milky-white, with just a hint of amber, you’ve hit the sweet spot for a potent, energetic high.
- The Chop: Cut your plants and trim away the large fan leaves.
- The Slow Dry: Hang the branches in a dark room with good airflow, a temperature around 65-72°F (18-22°C), and humidity around 45-55%. This usually takes 7-10 days.
- The Cure: This is the most important step for Sativa strains. A long, slow cure of at least 3-4 weeks (and ideally longer) is what will break down the chlorophyll and allow that complex tropical fruit flavor to fully develop. Be patient it’s the secret to top-shelf Sativa.
Frequently Asked Questions
What are the effects of Cinderella 99 really like?
It’s a classic potent sativa high. It starts with a powerful, euphoric, and uplifting cerebral rush that’s great for creativity, focus, and energy. It’s a fantastic daytime strain that will inspire you.
Why is C99 sometimes called a “holy grail” strain?
It earned that nickname because it was one of the first strains to offer a powerful, tropical-tasting sativa high but in a plant that grew short and flowered fast like an indica. For growers in the 90s, it was the best of both worlds and a true game-changer.
Is this a good strain for beginners?
Yes! Its genetics make it a resilient and manageable plant, especially for a sativa. The only extra step is identifying and removing the male plants, but that’s a great skill for any new grower to learn.
What’s the biggest benefit of growing “Regular” seeds?
Regular seeds give you both male and female plants. If you’re interested in breeding, you need the males for their pollen. Growing regular seeds is the most natural way to cultivate cannabis and gives you the power to create your own new strains.
How big will my yield be?
C99 is a legendary yielder. It grows into a solid, multi-branched plant, and if you use some simple training techniques, you can expect a very bountiful harvest of top-quality, potent buds.
