Types of greenhouses that are best for corn production

There are many types of greenhouses that can be used for growing corn. A typical greenhouse is made up of a series of plastic or glass walls, with a roof to keep the heat in. The most common type of greenhouse is the “glasshouse”, which allows light to enter but blocks out most of the sunlight. This type of greenhouse is best for raising plants that need lots of light, like flowers and tomatoes. 

Another type of greenhouse is the “trellis” greenhouse. These greenhouses use a series of supports instead of walls, allowing more sunlight in and keeping the heat in. Trellises also allow air to circulate better, so this type of greenhouse is good for plants that need lots of air circulation, like corn.

How to harvest and store corn crops in a greenhouse?

Harvesting and storing corn crops in a greenhouse can be done using a number of techniques.

Harvesting corn: corn can be harvested when the silks are brown and the husks are removed.  One popular method is to cut the corn stalks just above the ears with a sickle or scythe, then snap the ear off. Another way is to use a grain drill to remove the corn kernels directly from the cob.

Storing corn: you can harvest it by cutting the stalks down at ground level. You can then store your harvested corn by drying it or freezing it. It is important to collect all of the corn cobs and any ear debris, as these materials can provide food for pests and diseases. It is also helpful to bag or wrap each cob in plastic before storage. The ears should then be dried for 12 hours before being stored in an airtight container.
