Open ventilators a little on sunny days but close them again quite early in the afternoon, before the temperature begins to drop, to retain as much of the heat of the day as possible.
Watering ...
If the weather be warm, and the glass rise several degrees higher, open the ventilators, exclude the sun, and make a slight blaze in the chimney, to cause a circulation of the air. Widen the spaces for the worms.
Ensure you can open and close the ventilators easily from the ground. Having to use a step-ladder to open vents makes it less likely you'll use them. Keep the ventilators in good repair and well lubricated so you can operate them easily.
The best combination is to have ventilators in the sides and the roof to create a chimney effect, as cool air enters through the side vents and is expelled through the roof vents as it warms.
Other options include using a compost aeration tool (available from garden supply companies) or a ventilator stack. Stacks can be made out of perforated plastic pipes, chicken wire wrapped in a circle, or bundles of twigs.
structure of the greenhouse that provision is made for the opening of ventilators.
Insulation may well still be useful at night during spring, but on sunny days the
temperature will soar and full ventilation may be necessary.
So many passion vines voluntarily went groping out of greenhouse ventilators in August that gardeners couldn't help but take the hint.
Another type is like a very long corkscrew, which is easy to turn into the pile to make holes. For the lazy composter, there's even a 3-foot-long ventilator that attaches to a power drill. Expect to spend from $15 to $30.
