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
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.

This F1 Fast is fast and very nice indoor hydro. But my outdoor looking even better small plant but looks amazing. Hoping to get half to a pound maybe more of this plant. Plus it's close to half way true flower now August 4th in Canada that super nice. No red out yet but hoping for it. Indoor was so tasty

Red Mandarine F1 FAST Feminised Seeds
Wow just wow. First time growing this strain and I grew other fast versions as well and nothing came close to the mold resistance this strain has. The buds are soooo pretty and smell like gas, sweet mild citrus(not like oranges or lemons), with hints of pine. Grows big leaves and big buds. I had two different phenos grow. One that was purple and one that didn’t turn purple. It’s not the biggest producer but grows awesome. I’d recommend this strain to beginners. Such a strong strain with great genetics. Sweet seeds really did well with this strain. Every plant was harvested near the end of September.

Red Mandarine F1 FAST Feminised Seeds
Nice grow, and it does clone easy as one of the other reviewers stated. Smokes pretty gd also. Mines didn't turn red, very disappointed. If it's due to the weather, than it should mention that in the description. I have a clone so I'll be testing it out in the cooler temperatures. Stay tuned.

Red Mandarine F1 FAST Feminised Seeds
All seeds popped in rapid rooting plugs several months apart. Fast veg stage. Very susceptible to spider mites. Used 86 solution to battle in veg and an alcohol/water mix to battle in flower. This strain clones very easily in ph'd water with airstones or rockwool with clonex. Smoke was pretty good. Very mellow. Due to fighting with spider mites so much I harvested at week 6. Flowered 2 plants under an hlg 600. 1 plant Ran just water and the 1 other with the mills nutrients. Yielded 4oz. Smoked was nice abd mellow. This strain smells amazing. Cant wait to make butter and test shortly.
