Because the temperature within the hothouse increases above 21 levels C (70 levels F), a ventilator within the roof is partly opened up with a special temperature-sensitive device. When the temperature keeps rising, the vent is going to be fully opened up.
Shading could be supplied by draw-lower blinds within the glass or plastic, pulled lower by hand when there’s strong sunshine. When the sun becomes hidden by clouds the blinds could be folded support.

A less expensive alternative may well be a heated propagating situation with no mist unit – but this is less efficient for cuttings that are hard to root. However, a heated propagating situation could are also available in handy for germinating seeds in Feb or March (later around most seeds could be germinated inside a pot engrossed in glass or plastic.)
There could also be staging across the green house side supporting rows of cuttings that have already rooted. These may be put right into a cold frame for hardening later around, prior to being transplanted towards the garden the next spring.
More staging holds plants in trays of wet sand to maintain automatic watering.
