Green Crack Fast Seeds

A faster-flowering take on the classic Green Crack line, bred to deliver its signature vigor and bright coloration in a shorter bloom cycle. Green Crack Fast Seeds retain the original’s strong growth habit, high resilience, and uniform structure while completing flowering up to two weeks sooner—ideal for growers who want reliable performance with quicker turnaround times.

Green Crack Fast plants develop rapidly, forming medium-tall frames with strong lateral branching and dense, resin-rich clusters. The foliage stays a deep, glossy green, sometimes showing subtle purple streaks during late bloom. Known for its lively growth and adaptability, this fast version keeps the energy and consistency of its lineage while enhancing early-maturing traits for temperate and northern regions. Its balance of speed, vigor, and ornamental appeal makes it a dependable choice for both production and breeding projects.

Start seeds indoors 4–6 weeks before the final frost or light cycle transition. Maintain soil temperatures between 70–80 °F / 21–27 °C and provide full sun or strong artificial light. Green Crack Fast thrives in nutrient-rich, well-drained soil and responds well to pruning and training for broader canopy development. Expect flowering to complete in approximately 7–8 weeks, producing lush, uniform plants with vibrant finish.
