Mini Greenhouse Buying Guide
There are important issues to consider before making a greenhouse purchase. These include the size of the greenhouse, the materials used in its construction, ventilation and insulation issues.
Size is obviously the first issue to be considered. Since it’s a mini greenhouse, knowing the amount of space available is important. If the greenhouse is too big, then you will have no space for it, and if it is too small, then you have not optimized your space. So take measurements first, and know how much space you actually have.
Most mini greenhouses are covered with plastic sheets, as a glass is usually beyond the budget here. This leaves the material for the frame. Metal and wood are the major options, although metals like aluminum or steel last longer than wooden frames, and are more used. Wood is still a great material, but it is more suited to special cases.
Depending on the size and style of the greenhouse, ventilation should be considered. Most mini greenhouses offer a roll-up entrance that is also used for ventilation. Larger greenhouses may offer roll-up windows on the sides, so you have to make sure that you will be able to ventilate the greenhouse when needed, by planning for enough space around it.
While most mini greenhouses feature plastic covers, the thickness and the clarity of the material is another issue. You can have clear covers, diffused and semi-diffused covers. For general use, diffused covers are more preferable, while clear covers are better suited for germinating seeds only. Depending on the weather conditions in your location, you may also want to consider thicker or multi-walled covers for better insulation.
