Growing OG 18 Kush Cannabis Extraction

OG 18 Kush Cannabis Extraction is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 9-11 weeks with yields of 400-550g/m2. Plants typically reach 100-180cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with the dense, heavy buds this strain produces.
