JACKHERERSEEDSBANK

Germination and early seedling development set the foundation for a successful hydroponic cycle. To get the most from your jack herer strain seeds, use the paper towel method or a dedicated germination cube, maintaining temperatures between 72–77°F (22–25°C) and relative humidity around 70%. Once the taproot reaches approximately 1 cm, transfer seedlings into your chosen hydroponic medium — rockwool cubes and clay pebbles are both excellent options. At this early stage, keep nutrient concentrations low (EC around 0.8–1.0) to avoid burning the delicate root system.
