Climate stability
Avoid wild day/night swings. Vent in the morning; shade in peak heat if needed.
Dome
Dome garden quality levers
A dome extends the season, but heat and humidity pile up. Manage climate before adding plants.
Best levers
Ventilation
Air exchange often matters more than extra heat. Still air = disease risk.
Humidity and disease
High RH + leaf wetness = mould. Water at the root, not the leaves; leave space between plants.
Drip irrigation
Steady drip reduces surface-watering swings. Pair with soil moisture monitoring.
Season extension
Start with seedlings, protect from frost, finish in time in autumn. Don’t overcrowd varieties.
