A fast flowering hybrid strain of C99 with Blueberry
This a very successful hybrid of short flowering indica Cinderella 99 with the Original Blueberry. The result of these two lines cross was the plant that incorporates the best flavors of Thai sativa parent genetics. It will significantly stretch at flowering. But despite this buds require no manicuring. Fast Version of Cinderella99 X Blueberry hybrid will provide you with a huge crop of solid, densely covered with trichomes and resin nugs in just 45 days. Outdoors plant will be ready for harvest in mid-September.

Early/Fast outdoor timeline

Fast / Early strains keep the photoperiod growth pattern, but they begin flowering earlier and usually finish sooner — helping outdoor growers harvest before late-season weather becomes a problem.

Stage 1
Germination / Early Start
March – April
Wait for: warmer days, lower frost risk, stable spring weather
Watch for: cold snaps, excess moisture, slow early growth
Stage 2
Seedling / Transplant
May
Wait for: steady light, mild conditions, protected early growth
Watch for: transplant stress, pests, wind exposure
Stage 3
Vegetative Growth
June – July
Wait for: long bright days, healthy expansion, strong structure
Watch for: overcrowding, nutrient issues, insect pressure
Stage 4
Flowering
From late July
Wait for: first signs of bloom, good airflow, settled conditions
Watch for: humidity, mould pressure, poor weather
Stage 5
Harvest
From early September
Wait for: ripe trichomes, dense finished flowers, harvest readiness
Watch for: cutting too early, rain, bud rot
Fast / Early strains keep the photoperiod growth pattern, but they begin flowering earlier and usually finish sooner — helping outdoor growers harvest before late-season weather becomes a problem.

Indoor Early/Fast timeline

Fast / Early strains are most valuable outdoors, where earlier flowering and shorter bloom times help growers harvest before poor autumn weather. Indoors, their main benefit is a faster flowering phase than photoperiod versions.

Theses started to grow then just died for no reason. They sent out a replacement and those did not even sprout and I was told that you can only get one replacement so I really just wasted $80. All of the seeds that I purchased and all of the replacements I didn’t get one viableplant.

2 out of 3 germinated - both were stunted at about 2 inches of growth at 10 weeks - I’ve abandoned and started over - disappointing

Thanks for your review. We do test seeds from all the batches of seeds that we sell - and only release for sale seeds that test over 95% germination - we are therefore very confident with the quality of the seeds that we sell. We also hold our suppliers to the same high standards. This said these are live products and competencies & environments vary so we try to help customers if they have issues. Please reach out to our customer service team to see what they can do to help, and check on our blog for our recommended germination techniques. Best Seedsman
