Here's some data for you, I see people share it a lot in reviews here 📊✅ Grow Time: 4 weeks Flowering Time: 50 days Yield: 2.3 oz/plant (organic soil, no CO2) Training: LST only Resistance: No pests, slight sensitivity to PM (controlled by airflow) Bag Appeal: 9/10 (dense, frosty, minimal leaves) Smoke Report: Clear euphoria, no burnout. Verdict: If you need a reliable, fast-finishing strain with commercial-grade bud, stop looking. It's right here.
