Growing Tips & Our Take
GMO Cookies is a strain that thrives when given the right care, but she’s far from demanding.
She does best in a warm, Mediterranean-like climate, but thanks to her resilience, she can handle cooler temperatures as long as humidity is well-managed.
Her solid resistance against pests and mold makes her an excellent option for growers looking for a low-maintenance, high-reward strain.
Her naturally sturdy branches allow her to support heavy buds, but a little low-stress training (LST) can help optimize her structure for even bigger yields.
Since her buds get incredibly dense, maintaining good air circulation is essential to prevent mold issues in late flowering.
She’s considered a medium-difficulty strain, meaning beginners can try their luck, but experienced growers will be able to push her full potential.
What impresses us most? The sheer power and density of her buds.
Trichome-covered, rock-hard, and loaded with potency, she’s the kind of strain that makes every harvest feel like striking gold.
