Greenhouse Workshop Notes
Profiting from your Greenhouse Effect: the Essentials of Season Extension
On February 28 and 29, 2012 almost 90 attendees joined ACORN and renowned organic greenhouse growers and industry
representatives for a practical workshop on greenhouses, hoop
houses and season extension techniques.
Sessions covered the basics of greenhouse selection and production,
including soil fertility, transplants, grafting, plastic selection and
heat and water management. Speakers discussed how to choose the
right greenhouse for your operation, construction tips for high tunnels
and low tunnels, and other season extension techniques.
The session was sponsored by ThinkFarm, NRC-IRAP, OCTA Greenhouses, Multi-Shelter Solutions, and Halifax Seed
