Tropicanna Poison F1 FAST is a photo-dependent, feminised, red-flowered and ultra-fast version of one of the “Super Strong” varieties of the most famous Cookies family in the USA...namely Tropicanna Cookies (Girl Scout Cookies x Tangie).
Results from crossing an elite clone selected from Tropicanna Cookies, with a red flower phenotype, and our appreciated red flowered Red Poison Auto ®.
Very productive and resinous strain that produces THC levels of up to 24%, and very high levels of terpenes.
Excellent aroma and flavour, very sweet, intense and dense, with shades of mango, earthy and woody brushstrokes, and slight Skunk background.

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.

These beauties are doing wonderful so far. This is my first grow, and they have handled everything I have thrown their way and still look amazing. Sad that only one of the 7 actually turned red through, was excited to see more color. Will update once harvest and samples for flavor/review. So far so good! UPDATE: Unfortunately, all 7 of my plants hermied and seeded :( I attribute to grower error since I am new, but I did say I would update. Will still definitely be using seedsman in the future and excited for my next grow!

The Red Mandarine already in flower 3 to 4 weeks in easy the Tropicanna Posion not even started to flower yet making it Femenized seed but not fast plus only 3 of the seed pop. So next or this will be off my order list 😜. But their Red Mandarine so ordering more for my outdoors

Not Five yet. Only popped 3 of the 7 I got. All three popped and are super vigorous in hugo blocks getting GH nutes. 4 weeks into flower now and no colors showing. Gonna be salty if they are boring as they description reads 80% show red coloration. Also, at 4 weeks, they do not look like they will be anywhere near done by six unless something drastic happens. Very hazy aroma so far and as I said, no colors. All in all two stars off for now and will change my rating should things change. The good is that they take stress like champs and are massive and healthy under the ROI-E720.
Please note that some customers choose to leave a rating without writing a review, and because of this the number of ratings will differ from the number of reviews.
