Alton Greenhouse Ventilation


Clean, fresh air in a greenhouse is considered as important to plants as regular watering.

Greenhouse ventilation is very important and there is far more to ventilation than meets the eye and it is not just simply opening vents or the door.

Your need to be kept your plants at as constant a temperature as possible, especially during the spring months, when your seedlings and cuttings are just emerging or rooting.

An automatic vent opener comes into it's own as the temperature starts to rise, thses control the amount of air and heat build up in your greenhouse.

It is during the summer months when the temperatures shoot up quicly and when you have your tomatoes or lettuce growing, these will need more air flow and you will need a current of fresh air to flow through your greenhouse, this is in order to keep your plants cool and free from botrytis, especially at ground level where plants are vulnerable to mould.

The unique Alton ventilation system, which you will find on all Evolution Greenhouses, is proven to produce healthier plants and higher yields over the years.
