Inside, the temperature can change quickly. A mild spring afternoon may feel much warmer once the sun reaches the glazing. Roof vents let the hottest air out, while a lower vent or open door keeps
air moving. An automatic opener is useful when nobody is home, though it works best alongside other ventilation.
Watch the chosen position at different times of day. Nearby walls, fences and trees can leave a corner shaded for longer than expected. A sunny south-facing spot may need more ventilation in summer.
East-facing gardens get their strongest light earlier, while west-facing positions warm later in the day.
The crops still need to suit the light available. Checking
plant light requirements.
before deciding what to grow helps avoid weak growth and poor fruiting in a shaded position. Tomatoes and cucumbers prefer brighter spots, while lettuce and other young salad leaves are more forgiving
when the planting plan matches the available light.
