Washington Growing Calendar
The Evergreen State’s Pacific Northwest climate splits dramatically at the Cascade Range — the wet, temperate west side around Seattle contrasts sharply with the dry, continental east around Spokane and the Yakima Valley. Western Washington’s 175-day growing season, volcanic-loam soils, and mild temperatures create ideal conditions during the dry summer months, though October’s returning rains demand precise harvest timing. Recreational since 2012 with a 6-plant home grow limit, Washington has built one of America’s most sophisticated growing communities. The state’s craft beer culture has a direct parallel in its cannabis scene — terroir-driven, quality-obsessed, and deeply regional.
Washington frost dates: Last frost March 25-April 25, first frost October 10-November 5 (160-200 days frost-free days). Best growing regions: Puget Sound (Seattle/Tacoma), Yakima Valley (dry, agricultural), Spokane/eastern WA (continental), Olympic Peninsula (wet). Elevation range: 0-14,411 ft (Mount Rainier).

Washington Growing Tips
Leverage the Dry Summer
Temperate climates offer dry summers perfect for cannabis. Low humidity during flowering means minimal mold risk — a significant advantage over eastern states.
Plan for Fall Rains
Fall rains arrive before some strains finish flowering. Choose varieties that finish by mid-October, or use a greenhouse to extend your dry window through November.
Take Advantage of Mild Temps
Moderate daytime highs (70–85°F) and cool nights create ideal conditions for terpene and resin development. Less stress means higher quality harvests.
Rich Soil Advantage
Pacific Northwest soils are naturally rich and well-suited to cannabis. Amend with compost and perlite for drainage, and let the native biology do the work.
