Hope Blooms is a North End Halifax community garden and salad dressing business run by inner city youth with help from mentors. It began in 2008 as a garden project with less than 12 kids involved, and has grown exponentially.
The children plant seeds, tend crops, and turn their produce into organic dressing which is sold locally. In 2013, they appeared on CBC’s Dragons’ Den asking for an investment to expand their business and walked away with $40,000 towards a new greenhouse.
Build Right Nova Scotia heard about the great work the kids of Hope Blooms were doing and wanted to get involved. So, the tradespeople of Build Right constructed a state-of-the-art greenhouse for the youth-run social enterprise. Build Right Nova Scotia contributed all of the supplies and labour for the facility, allowing for the Dragons’ Den money to be invested into other aspects of the program and the community. The Hope Blooms youth were very involved in the process and their ideas have been incorporated into the project.
This greenhouse is very special, here are some fast facts about the structure:
- The greenhouse is a 1,500 square foot, off-grid building;
- It draws nearly all of its energy from the sun;
- It is glazed with 525 sq. ft. of twin-wall polycarbonate (which insulates 60 times better than a comparable single thickness of glass);
- Solar-powered vents open automatically when it is hot and close when cool;
- The walls are nearly two feet thick and incorporate tremendous thermal mass and high levels of insulation
- The walls are constructed using insulated concrete forms made from concrete and waste wood chips
- Rainwater, to be used for irrigation, is harvested from the roof and collected in a storage system located inside the building;
- The greenhouse features a gravel floor that allows for improved plant transpiration (“breathing”);
- The compost bin has a capacity of 75 cubic yards. Heat given off by decomposing compost warms the air inside the greenhouse. This improves the greenhouse’s performance on cool, cloudy days and extend the growing season.
