Aroma & Terpenes

Critical Mass Auto thrills fans of heritage genetics with an enticing, deeply sweet and fruity bouquet.

Inhalation reveals a rich, dense smoke that glides smoothly across the palate, finishing with sweet fruit notes. The high is exceptionally balanced and versatile: Initial tokes provide an uplifting, serene mental clarity that melts away stress and boosts mood, followed promptly by a deeply soothing physical relaxation that unwinds tight muscles without causing couch-lock.

Grow Report & Pro Tip

In indoor tents, Critical Mass Auto demonstrates vigorous, forgiving, and resilient growth, making it easy for beginners to produce record-setting yields right away. Plants maintain a compact, bushy structure with a strong central stalk and multiple sturdy lateral branches, reaching heights between 80 and 100 cm. In an astonishingly brief life cycle of just 7 to 8 weeks from seed to harvest, flower clusters swell into massive, rock-hard colas. Indoor cultivators reliably pull heavy yields ranging from 450 to 600 g/m². Outdoors, this productive autoflower flourishes on balconies, sunny terraces, or garden beds, effortlessly yielding 200 to 350 g per plant. Thanks to its rapid cycle and compact stature, outdoor growers can easily complete multiple successive outdoor cycles in a single season.

Pro Tip: Plant germinated seeds directly into their final 11- to 15-liter containers to prevent transplant shock, and maintain strong air movement during late bloom to protect the ultra-dense flowers against mold.
