Growing Timeline - Outdoor

Rosetta Stone follows a photoperiod schedule, meaning its flowering is triggered by changes in daylight. Here’s a general timeline for outdoor cultivation:

• Stage 1 - Germination / Early Start: March – April. Wait for frost risk easing and stronger spring light. Watch for cold snaps, slow starts, and excess moisture.
• Stage 2 - Seedling / Transplant: April – May. Wait for milder nights and settled weather. Watch for transplant shock, wind exposure, and pests.
• Stage 3 - Vegetative Growth: June – July. Wait for long days, regular feeding, and healthy expansion. Watch for overcrowding, nutrient issues, and insect damage.
• Stage 4 - Flowering: August – September. Wait for shortening days, dry airflow, and branch support. Watch for mould, botrytis, high humidity, and bad weather.
• Stage 5 - Harvest: Late September – October. Wait for ripe trichomes and dense finished flowers. Watch for autumn rain, rot, and early frosts.

Growing Timeline - Indoor

Indoor growers have more control over the cultivation of Rosetta Stone, allowing them to manage size, shape, and the timing of flowering:

• Week 0 - Germination: Focus on strong early establishment. Watch for inconsistent starts and excess moisture.
• Weeks 1–2 - Seedling: Aim for stable structure and healthy growth. Watch for stretch and early stress.
• Weeks 3–6+ - Vegetative Growth: Work towards achieving the desired plant size and canopy shape. Watch for overcrowding, uneven growth, and training stress.
• Weeks 7–12+ - Flowering Phase: Ensure strong flower formation and steady development. Watch for humidity, airflow, and support issues.
• Harvest - Harvest Window: Wait for finished flowers and mature trichomes. Watch for cutting too early or pushing too long.
