Unit 7 × Unit 12
Cinderella 99 × Sour Diesel
The Diesel Rocket. Cinderella 99 — one of the most legendary fast-flowering sativas ever created by Brothers Grimm — crosses with the iconic Sour Diesel to produce a fuel-forward sativa powerhouse that hits like afterburners igniting.
Cinderella 99 (C99) is Brothers Grimm's legendary work from the late 1990s — a compact, fast-flowering sativa with explosive tropical-citrus-pineapple terpenes, soaring creative effects, and exceptional yield for a pure sativa. The 50-56 day flowering time is almost unheard of for true sativa genetics. It's a workhorse strain that performs consistently and rewards growers with quality, speed, and bag appeal.
Sour Diesel needs no introduction. The iconic New York fuel strain — petroleum-forward pungency, soaring cerebral effects, legendary status in cannabis culture. Sour D's petroleum-citrus terpene signature is one of the most recognisable aromas in the plant kingdom. Its potency (22-26% THC) is moderate by today's standards but its effect quality — clean, energetic, motivating — remains unmatched.
Together in F1, C99 contributes its incredible speed, tropical-citrus brightness, and sativa structure while Sour Diesel layers in petroleum depth, iconic fuel pungency, and old-school sativa cerebral power. The result is a fast-finishing sativa (56-63 days) that smells like a citrus-soaked fuel depot and hits like stepping on the accelerator at full throttle. Old-school power. Modern efficiency.
Best Growing Method: Excellent for indoor, outdoor, and greenhouse. One of the more forgiving strains in the catalog
Height: Medium-tall (90-150cm). C99 keeps the stretch manageable. Expect moderate stretch in first 2-3 weeks of flower
Flowering Time: 56-63 days from flip. One of the fastest sativas you'll grow. Don't mistake early readiness for unfinished product
Training: Responds beautifully to topping, SCROG, and LST. C99 genetics create excellent branching structure
Nutrients: Moderate feeder. Both parents are relatively unfussy. Standard feed schedule works well. Avoid overfeeding nitrogen in flower
Climate: Adaptable. C99 genetics handle South African heat reasonably well. Diesel genetics add resilience
Harvest: Harvest when trichomes are mostly cloudy for maximum energy. Adding amber tones brings body relaxation to the otherwise pure sativa effect
Effects: Afterburn lives up to its name. The effect onset is immediate — within minutes of consumption, Sour Diesel's cerebral sativa ignition fires, creating a rapid surge of energy, mental clarity, and uplifted mood. C99's tropical brightness adds a joyful, creative edge to what could otherwise be a purely functional Sour D experience. Effects are sustained and clean — no ceiling crash, no anxiety at reasonable doses, just long-lasting energetic clarity. Excellent for daytime use, creative work, physical activity, social engagement. This is old-school sativa energy with C99's legendary clarity and focus.
Primary Terpenes:
Flavor Profile: First inhale: unmistakable Sour Diesel fuel — sharp, petroleum-forward, slightly sour. Then C99's tropical pineapple-citrus cuts through in the mid-inhale, creating a fuel-soaked tropical combination that's surprising and addictive. The exhale is a long diesel-citrus fade with slight herbal sweetness. The classic Sour D skunk is present but elevated — brighter, more complex, more pleasant. Long-lasting flavor that coats the palate. Old-school cannabis lovers will recognise and celebrate this immediately.
Not recommended for: Evening use, those seeking relaxation or sedation, beginners sensitive to cerebral sativa effects, or anyone who dislikes fuel/diesel terpene profiles.
