Grow the ideal seedling that is conditioned for out planting is easier when growing them in a retractable roof greenhouse.

From seed to hardening, many of North Americas leading suppliers of tree seedlings use Cravo retractable roof greenhouses as their tool to ensure that their seedlings meet the specifications.

The A frame house is ideal to allow plants to be grown from seed until ready for shipping. Add a blackout- heat retention curtain system to induce dormancy and to help retain heat during cold conditions. Growers can choose to lengthen the growing season since crops can be protected from frost and be quick shut down, simply by being able to open and close the roof.

Some growers have added a retractable flat roof for blackout and frost protection for inducing dormancy on crops that have already been moved to outside holding areas. The same house can be used to protect tender seedlings from unseasonable frost.
