Types of mini greenhouses for seedlings
Mini greenhouses for seedlings and greens are divided into three groups (depending on the installation location):
- Outdoor structures are designed for open areas. They can be placed as a separate structure in a garden or vegetable patch, or have one wall adjacent to another structure, such as a house or shed.
- Indoor greenhouses are placed indoors. They can be used for seedlings and heat-loving houseplants. A mini greenhouse on a windowsill is an excellent option.
- Portable – in summer, they can be placed in a summer house, on a balcony, or on a veranda. In colder weather, they can be moved indoors.
Also, all structures for plant protection are divided into frame and portable.

The first option involves lathing, which can be made from the following materials:
- aluminum - parts made from it are fastened with bolts and nuts;
- steel pipes - welded using a welding machine;
- wooden beams - connected with screws and sealant;
- PVC pipes are fastened with a soldering iron.
The walls are made of glass, polyethylene film, or polycarbonate, which are attached to the frame. This mini greenhouse cannot be disassembled once it's built, so moving it to another location will be difficult.
Portable units are mobile structures. They resemble a small cabinet, are miniature in size, and take up minimal space.
The portable greenhouse consists of the following elements:
- a rack on legs or rollers, made of wood, plastic or metal;
- shelves made of metal mesh or wooden slats for placing plants;
- a cover that provides thermal insulation and opens from the front or top.
Helpful information! If needed, heating and lighting can be installed in mini-structures (just like regular ones).
