You can expand and adapt your greenhouse as needs change. Working with Solexx™ is so easy that adding base vents and/or exhaust fans can happen at any time. We make some basic recommendations for you to consider with any greenhouse purchase. Units 12' or less can get by without adding power exhaust fans or intakes depending upon year-round use and climate.
Some items we highly recommend are the 'solar louver opener' and base vents. Each greenhouse comes with a manually operable louver for venting, but the solar louver opener is adjustable and will insure that your greenhouse is vented when you can't be there to open the louver by hand. Base vents really help for cross ventilation. We recommend one for every 8' on each side of the greenhouse.
