Potent, high-yielding strain with a powerful dank smell.
King Kong FAST Feminised is a cross between Gorilla Glue and Fatso, with the added advantage of shorter flowering times. Atlas Seed claims 99.99% female plants from these FAST photoperiod seeds.
King Kong FAST has excellent vigour in its vegetative growth phase, developing with larger than average internodal length and lower than average side-branching. Its energies are directed towards producing sticky, resinous flowers. Growers are advised to establish a well-supported canopy during the veg. phase before flowering commences for this high yielder. Flowering takes 7 - 9 weeks. Moderate mould resistance and good tolerance of both cold and drought conditions.
King Kong FAST has a dank, Skunky, fuel smell. THC production is very high at 20 - 28%.
N.B. Atlas Seed FAST flowering are described as "semi-full term".

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.

March – April
Wait for: warmer days, lower frost risk, stable spring weather
Watch for: cold snaps, excess moisture, slow early growth
Stage 2

May
Wait for: steady light, mild conditions, protected early growth
Watch for: transplant stress, pests, wind exposure
Stage 3

Stage 5
Harvest
From early September

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.
