Red Poison Auto®Tangie (California OrangeSkunk Hybrid)
Fast, red strain with good yields.
Sweet Seeds' first red flower photo-period variety. Hybrid resulting from the cross between our Red Poison Auto® and a photo-period elite clone of Tangie (California Orange x Skunk hybrid), a rare phenotype of red flower, with a wonderful aroma and intense tangerine flavour.
Produces very resinous and productive buds of beautiful red flowers, which are ready to be harvested in just 7-8 weeks.
The aroma of this variety is possibly the most exquisite of all the red flower varieties on the market, it has a powerful sweet and citrus tangerine aroma, with fresh brushstrokes of blue cypress. Ideal for extracting concentrates of enormous aromatic quality and great brightness by the reddish and pink tones of its resin.

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
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.
