Horticulture reference
Cannabis growing by climate
The Lockbox climate guides collect documented protocols for cannabis cultivation in each of the major climate bands growers operate in around the world. Each regional reference describes the season windows, light and temperature considerations, documented strain selections from the Lockbox library, and the pest and humidity pressures most-cited in published grower reports for that band. The voice across these pages is reference-oriented — numbers reflect what is documented in horticulture literature and in published hobby-scale reports, not personal recommendation. Nothing here is medical, legal, or growing advice; the legal status of cannabis cultivation varies considerably by jurisdiction, and readers are responsible for understanding the law where they live.
