Building Your Own Greenhouse – Cold Frames and Grow Racks
For homes with limited garden space and small apartments with small patios, cold frame greenhouses and grow racks are ideal. These are miniature greenhouses that are specifically designed where space is an issue or space and growing capacity are to be augmented. There are various design options that could fit an apartment or small houses. These greenhouses are designed as attractive additions to patios and walkways.
Cold frames structure
A cold frame greenhouse is the simplest and sometimes the smallest of greenhouse types. Advantages of the cold frame greenhouse aside from being inexpensive are that it does not use any artificial source of heat. The heat that it uses is the heat that is filtered through the cover. The cold frame model is best at protecting and strengthening tender flowers, herbs, and plants, an interim growth and cultivation environment if you will, before they are transplanted outside. It is good at protecting sensitive plants during winter and cold months. Even when cold frame greenhouses are generally designed to be small, they are good at supplementing spaces for big projects. When not in use cold frames could be used as storage for garden supplies and seeds. Many cold frame structures are designed with single or double poly coverings that are easy to assemble and disassemble.
Cold frame structures are designed for basic plant protection only and are not recommended in areas where there are extreme weather changes and are very windy. The cold frame model is not ideal for growing exotic and delicate plants year round as these types of plants need requirements that closely approximates its natural environment. For temporary sheltering and caring of plants however, cold frame greenhouse structures have advantages.
The Grow Racks
Grow racks are mini greenhouses next in size to the cold frame type. For the plant enthusiast, these types are designed to be affordable, practical and low maintenance. They are constructed to be lightweight, compact and portable to fit limited spaces. Grow racks are often designed to accommodate adjustments or removal of shelves. The tiered design enables the gardener to make adjustment on the requirements of the plants that are currently grown. The steel frames of this greenhouse type are painted, and are covered with Velcro to keep the humidity and the heat in. The Velcro is fitted with zipper for adjustments in the temperature.
