Indoor Crop Cycles

Indoor crop cycles refer to the controlled growing periods cultivators use when producing cannabis in enclosed environments with managed lighting, temperature, and humidity. Unlike outdoor grows that follow seasonal photoperiods, indoor operations can initiate flowering on demand by switching light schedules—typically from 18-24 hours of light during vegetative growth to 12 hours during flowering. Breeders and cultivators classify strains partly by their responsiveness to these artificial light cycles and their total time-to-harvest indoors, which varies significantly by genetic background. Some lineages complete full cycles in 8-9 weeks, while others require 11-13 weeks or longer, influencing breeding strategy and commercial viability. Understanding indoor cycle characteristics helps breeders select parent plants suited to controlled-environment production systems.

Breeders prioritize genetics with predictable flowering timelines and reliable light-cycle response when developing cultivars for indoor operations. Selecting for shorter, consistent cycle times reduces facility costs and increases annual plant rotations per square foot.
