STRAIN TRAITS
Strain Overview
This variety blends the heavy-yielding structure of Critical Mass with the resin-focused traits of White Widow Max Auto. The result is a compact plant that develops thick central colas supported by multiple lateral branches.
Its growth pattern favours uniform flower development and strong bud density, making it well suited to growers working with limited space or shorter seasonal windows.
Growing Information
Critical Thunder Autoflower grows as a short, bushy plant, typically reaching heights of 60–100cm. It performs well indoors and outdoors in warm climates and adapts easily to controlled environments.
The autoflowering lifecycle removes the need for light schedule adjustments, allowing growers to focus on basic care. Plants respond well to steady feeding and good airflow, with dense flower sites forming evenly across the canopy.
Flowering Time & Yield
Flowering completes in approximately 8–10 weeks. Indoor yields generally range between 300–400g/m², while outdoor harvests can be taken between July and September depending on conditions.
Beginner Suitability
This variety is suitable for growers of all experience levels. Its compact size, straightforward growth pattern, and short cycle make it easy to manage from seed to harvest.
Aroma, Flavour & Terpenes
The aroma is bold and pungent, combining sharp citrus notes with deeper earthy and woody undertones. As flowers mature, hints of spice and resin become more pronounced.
The terpene profile—led by pinene, ocimene, and terpinolene—drives a flavour that opens with citrus sharpness before settling into nutty, woody, and lightly spiced notes.
Why Choose This Strain
Critical Thunder Autoflower is an excellent choice for growers seeking a compact autoflower with strong bud density and consistent yields. Its short lifecycle, manageable size, and dependable structure make it a practical option for efficient grows in limited spaces.
