Frequently Asked Questions (FAQ)

What is the strongest cannabis strain currently?

While it changes with new genetics, current top contenders include Lemon Cherry Gelato, Dosimosa, and Runtz hybrids, all boasting THC levels around 30 %.

Is high THC the only measure of strong cannabis?

Not at all. While THC matters, strength also depends on terpenes, other cannabinoids, and how they interact (the entourage effect). That’s why some strains feel stronger than their numbers suggest.

Absolutely. With proper lighting, nutrition, and care, you can grow top-potency flowers from seed—especially if you start with high-quality genetics like Lemon Cherry Gelato.

How long do the strongest strains take to flower?

Most finish within 8–10 weeks of flowering. Faster-flowering options are available, but max-THC strains typically need a bit longer to fully mature.
