From Seed to a Sweet & Potent Harvest: The Full Grow-Along
This hybrid is resilient, a joy to cultivate, and thanks to its “Fast Version” genetics, incredibly efficient. Let’s break down its entire journey.
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 24 to 48 hours, 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.
The Vegetative Stage: A Vigorous Start
Because this is a Fast Version, the vegetative stage will be robust but a bit shorter than a standard photoperiod strain.
- Light Cycle: You need long “days” to promote strong vegetative growth. An 18/6 light cycle (18 hours of light, 6 of darkness) is perfect.
- Nutrient Needs: Your plant needs a balanced “grow” fertilizer with plenty of Nitrogen (N) during this rapid growth phase to build a strong, leafy structure.
- Train for More: 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 High-Speed Finish!
This is where Cinderella 99 x Blueberry Fast Version truly shows off. To trigger flowering, you MUST switch your lights to a strict 12/12 cycle (12 hours of light, 12 hours of absolute darkness).
Now, get ready, because this is quick! The flowering time is a wonderfully fast 7 to 8 weeks! You’ll see the plant explode with dense, resin-coated buds that may even show hints of blue and purple. The aroma will be a beautiful and complex mix of sweet blueberries and zesty citrus.
When you flip your lights, switch to a “bloom” fertilizer that is higher in Phosphorus (P) and Potassium (K) to support this rapid flower production.
Common Mistake to Avoid: High Humidity. Those dense 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.

Cloning: Preserve That Perfect Profile
Find a specific Cinderella 99 x Blueberry Fast Version plant with that perfect effect? Don’t let those amazing genetics go!
- 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 Flavorful Treat!
A sustainable grower uses the whole plant! The frosty trim from your Cinderella 99 x Blueberry Fast Version is a flavor goldmine.
This is THE perfect strain for making your own delicious edibles. Imagine blueberry-infused cookies or brownies! Infusing your trim into butter or coconut oil is a simple and effective way to use your trim. You can also make top-tier extracts like live resin to capture that fresh, fruity terpene profile in its purest form.

The Grand Finale: Harvest, Dry & Cure
You’ve made it to the finish line—and in record time! 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 perfectly balanced 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 60-70°F (15-21°C), and humidity around 45-55%. This usually takes 7-10 days.
- The Cure: This is the final step for a smooth and flavorful final product. Trim the buds and place them in airtight glass jars. “Burp” the jars daily for the first couple of weeks. A proper cure of at least 2 to 4 weeks will bring out that complex sweet and fruity flavor.
Frequently Asked Questions
What does “Fast Version” actually mean? Is it an autoflower?
No, it’s not an autoflower. A “Fast Version” is a photoperiod strain (meaning you still need to switch to a 12/12 light cycle to make it flower) that has been specially bred to have a much shorter flowering time than the original. It gives you the control of a photoperiod with nearly the speed of an auto!
What are the effects of Cinderella 99 x Blueberry really like?
It’s a beautifully balanced hybrid. It starts with a happy, euphoric, and uplifting cerebral rush from the C99 that’s great for creativity. This then melts into a soothing and relaxing body high from the Blueberry that melts away stress and pain.
Is this a good strain for beginners?
Yes! Its genetics make it a resilient and manageable plant. As long as a new grower pays attention to keeping the environment stable and doesn’t overwater, it’s a very forgiving and rewarding plant for our growing community.
What are the key challenges when growing Cinderella 99 x Blueberry Fast Version?
The biggest challenges are maintaining a stable environment (temperature and humidity) and preventing mold. Because its buds get so dense, good airflow is absolutely essential during the flowering stage to keep them healthy.
How big will my yield be if it grows so fast?
Don’t let the speed fool you! “Fast Version” refers to the flowering time, not a reduction in yield. This plant is known for producing very generous harvests of dense, high-quality, potent buds.
