Indica varieties typically require 8-10 weeks for flowering, while Sativa varieties take between 10 and 16 weeks. It is significant to recognize that flowering periods might fluctuate depending on environmental elements, with cooler nights for budding.Nighttime Temperature DropsNighttime temperatures should fall to about 18-20°C (64.4-68°F) during flowering. This drop of 8-10°C (46.4-50°F) from daytime highs encourages budding by simulating the cooler nights of autumn. It's a nudge to the plants, signaling that it's time to get those flowers going before winter sets in.This low-temperature HVAC developed by OptiClimate is designed for blooming.
