In order to protect the seedlings and plants in a greenhouse, the microclimate should be closely controlled. You need to be keen on regulation of carbon dioxide, water and sunlight every day. Air factor poses more complications than other factors and many novice farmers have a difficult time dealing with it. Dutch greenhouse fans can be used in creation of positive air current system.
You should not let air remain stagnant in the space for a long duration. This is because the process of transpiration is always ongoing. Plants need carbon dioxide for food production and the byproduct of this process is oxygen. Therefore, there is need for the air to be constantly recycled. In forcing air outside the space and bringing in fresh one, fans are needed.
Fans should be placed at the walls but near the flooring. Because the space is confined, the air which is at the bottom becomes heated and rises up. Therefore, there is a need to ensure that such air can find its way outside. It is possible to rely on nature for air movement but this will not be so efficient even though it will save you some money. You need fans to enhance this process.
There are exhaust and intake fan. However, it is beneficial to have one at the lower regions for pulling air outside. Exhaust fan make the air movement process proceed at a faster rate. They increase the inside pressure creating a pressure deficit which makes it possible for air to move outside. When carbon dioxide levels increase, you will observe that all the plants perk up. Fruit and flower production will therefore increase.
Apart from air movement, the fan also help in dispersion of humidity. In addition, a stream of recycled air is created around the vegetation. This way, there is no buildup of any of these factors which would make the plant life not to do well.
If the fans are not in use, you find that one area of the greenhouse becomes too hot than the rest. This will mean that crop production will not be uniform. Thus, you should control the duration and frequency of fan usage. Having consistent crop production enables you to maximize on the sales and the profits will improve too.
Do not shy away from purchasing fan because of the costs. Many people assume that fan cost quiet a fortune. To note is that there are so many brands in the market and you cannot miss products which are within your budget. Compared to the benefits, the cost of installation is very low.
Centrally placed fans are meant to facilitate air movement at the midsection if the greenhouse is huge. However, ensure you arrange them in circular manner for optimal functionality. This makes sure air is moved anticlockwise and also clockwise. Solar energy saves on energy utility bills when used in powering the fans. Nonetheless, only those who live in hot areas will benefit from this form of energy.
