11.4 Plant Stages and Watering Needs - Turbocharge Your Growing Knowledge

Summary

Key Points

• Proper seed storage requires cool, dry, and dark conditions, while germination involves providing moisture and warmth, with methods like the paper towel technique ensuring taproot emergence before planting. 0:13
• Understanding the eight stages of the cannabis life cycle, from seed storage to late flower, is crucial for providing proper care and attention to your plants. 0:24
• During the 1-3 week seedling stage, provide 16-18 hours of light, maintain specific temperatures (78-86°F day, 65-67°F night) and high humidity (70-80% RH), and water sparingly to encourage root development. 7:24
• The vegetative stage sees rapid root and foliage expansion, requiring transplanting into larger pots, optimal temperatures (72-85°F day, 63-70°F night), 65-70% RH, and a gradual increase in water and nutrients. 9:14
• At sexual maturity (8-10 nodes), plants begin to pre-flower, allowing for sex determination and removal of males, along with final transplanting and thinning of lower branches to prepare for flowering. 14:02
• To initiate flowering indoors, growers must switch to a 12-12 light cycle with uninterrupted darkness, which triggers blossoming and a rapid "turbocharge veg period" of growth. 17:06
• The early flowering stage requires a final thinning of the plant within the first week to 10 days, as the plant shifts focus from healing to generative growth, prioritizing flower development. 18:39
• Mid-flower focuses on flower production, necessitating reduced humidity (50-60% RH) to limit fungal disease risk, removal of yellowing leaves, and careful monitoring of nutrient uptake as biomass increases. 21:08
• In late flower, reduce humidity (45-55% RH) and temperature (max 80°F day) to prevent bud rot and enhance cannabinoid synthesis, followed by a thorough flushing 10-14 days before harvest to remove accumulated salts. 22:44
