Ultra Critical
Also known as: Critical Ultra, Ultra Critical Auto
Ultra Critical Strain Overview
Ultra Critical is a hybrid cannabis strain developed by combining Critical Mass and an undisclosed Ultra strain, though some sources suggest it may involve Ultra Skunk genetics. This strain emerged in the early 2000s from European breeding programs, specifically from the Spanish seed bank Dinafem, which has since ceased operations. The strain was bred to maximize resin production while maintaining the desirable effects and flavors of its parent strains.
Ultra Critical plants typically display dense, conical buds with a frosty appearance due to abundant trichome coverage. The coloration ranges from deep forest green to sometimes purple hues, with vibrant orange pistils weaving through the compact flower structure. The buds are known for their sticky texture and heavy resin production, making them popular among concentrate producers. The strain's aroma is particularly notable, combining earthy base notes with sharp citrus and skunky undertones.
This strain has gained popularity in both recreational and medicinal cannabis communities for its balanced effects and reliable performance. While not as widely documented as some mainstream strains, Ultra Critical has maintained a consistent presence in European markets and has been used in breeding programs to create autoflowering variants. The strain's genetics contribute to its resilience and adaptability to various growing conditions.

Ultra Critical Strain Growing Information
Ultra Critical is considered a moderate-difficulty strain suitable for growers with some experience. The plants have a flowering time of approximately 8-9 weeks indoors and are ready for harvest by late September to early October outdoors. Indoor yields typically range from 400-500 grams per square meter, while outdoor plants can produce 500-600 grams per plant. The strain performs well in both indoor and outdoor environments, preferring Mediterranean-like climates with consistent temperatures. Plants tend to be medium in height, reaching 100-150 cm indoors and 150-200 cm outdoors. Special considerations include providing good air circulation to prevent mold in the dense buds and implementing training techniques like topping or LST to maximize yield. The strain responds well to organic nutrients and benefits from a flush period before harvest.
