Do cheap greenhouses work?
There might be fewer extras, like shelves, ventilation, or reinforced doors, but that’s not to say they can’t work. For a small garden or a beginner gardener, a cheap greenhouse can still do the job. Just know what you’re getting: it’s practical, but it comes with limits. Generally, the decision to build or buy a greenhouse depends on your specific needs and budget. For example, if you have the necessary skills, time, and resources, building a greenhouse can be a practical option. However, understand that building a greenhouse isn’t necessarily cheap.Deciding whether it’s cheaper to build or buy a greenhouse hinges on your budget, time, and skill level. Building a greenhouse may save money if you already have tools and experience, while buying offers convenience and often includes warranties and professional support.
What are common greenhouse mistakes?
Mistake #1: Sealing the Greenhouse Too Tightly While that sounds logical, this is one of the most common and damaging greenhouse mistakes. Without fresh air moving through the space, humidity builds up fast. Plants release moisture through their leaves, and soil stays damp longer in cold weather. On a still, cold night, an unheated greenhouse typically stays 2-5C warmer than outside. On windy nights, that margin shrinks because moving air strips heat from the glass faster. By dawn, the temperature inside an unheated, uninsulated greenhouse can be only 1-2C above the outside air.
Which is better for a greenhouse, PVC or polycarbonate?
If you’re serious about building a long-lasting greenhouse for gardening, polycarbonate is the better option due to its durability, insulation, and weather resistance. However, if you just need a quick and affordable solution, a polyvinyl chloride greenhouse also works, albeit as more of a hobby greenhouse. The short answer is this: polycarbonate is usually the better long-term option when you need strength, transparency, weather resistance, and premium performance, while PVC is often the better fit when your priority is low cost, chemical resistance, and basic functional use.
