Genetics
Auto Massassin was developed by selecting vigorous plants with strong root development, healthy growth patterns, and reliable structure.
The hybrid combines the production traits of Monster MASS with the influence of AK47, creating an autoflower with strong flowering ability, good structure, and dependable performance.
This combination produces a stable and productive variety capable of growing large, resin-rich flowers while keeping the compact size and convenience expected from autoflowering genetics.
Flavour and Aroma
Auto Massassin offers a smooth terpene profile with plenty of depth.
Sweet aromas combine with sandalwood, fresh wood notes, and pine, creating a distinctive and refined fragrance. Light citrus tones add freshness, while the overall profile remains earthy, smooth, and highly aromatic.
The flavour follows the aroma closely, with gentle lemon and candy notes creating an enjoyable finish. Its balanced sweetness and soft character make it a great choice for growers who value flavour alongside performance.
Appearance
Auto Massassin produces high-quality flowers with impressive resin production.
Dense buds develop deep green colours across most phenotypes and are often covered in a thick layer of silver trichomes. Cooler flowering conditions may bring out additional colour variation, adding to the appearance of the finished flowers.
The combination of compact growth, heavy resin coverage, and dense flower formation gives Auto Massassin strong visual appeal.
Growing Information
Auto Massassin is a vigorous and forgiving autoflowering variety suitable for indoor and outdoor cultivation.
Plants develop quickly, building strong roots and rapid growth before moving into an intense flowering stage. Despite its productivity, it maintains a compact, bushy structure and can typically reach around 1 metre in height under optimal conditions.
With suitable care, Auto Massassin can produce harvests of over 100g per plant in approximately 60 days.
The variety responds well to gentle training methods. Light bending can improve light exposure across the canopy, while techniques such as crimping may help support better nutrient movement to developing flowers.

By combining Monster MASS production with AK47 influence and modern autoflowering traits, this variety delivers impressive results from a compact plant while maintaining strong resin production and enjoyable flavour.
For growers looking for a powerful autoflower with excellent structure, reliable performance, and premium flowers, Auto Massassin is a standout addition to the Critical Mass Collective collection.
