Problems with Polycarbonate Greenhouses

When contemplating a greenhouse purchase, the choice of material is often at the forefront of potential buyers’ minds. Polycarbonate greenhouses have become increasingly popular due to some benefits they offer, but there are also challenges associated with them. Here, we delve into the considerations surrounding polycarbonate greenhouses, the issues some owners have faced, and solutions to consider.

Advantages of Polycarbonate Greenhouses:

1. Strength in Adverse Weather: Some users have expressed satisfaction with polycarbonate greenhouses, highlighting their resilience, especially during storms. Unlike horti-glass, which is deemed fragile by some, polycarbonate greenhouses have shown resilience.
2. Price Point: Polycarbonate greenhouses can sometimes be more affordable than their glass counterparts. When on sale, the price difference can be even more pronounced, making them a tempting option for those on a tight budget.
3. Popularity in Europe: The widespread use of polycarbonate greenhouses across Europe can be taken as a testament to their functionality and reliability.

Challenges with Polycarbonate Greenhouses:

1. Perception of Fragility: There’s a common belief that polycarbonate greenhouses might be susceptible to high winds, with concerns about panels flying off or the entire structure blowing away.
2. Clouding and Algae Growth: After some time (around three months for some users), the polycarbonate glazing can begin to cloud up. This clouding not only reduces the amount of light entering the greenhouse but can also lead to algae growth inside the polycarbonate sheets. This makes cleaning challenging, if not impossible.
3. Comparison with Glass: Many are quick to compare polycarbonate to the traditional glass greenhouses. Glass has been in use for generations and is generally considered a tried-and-true material. The relatively minor price difference between polycarbonate and glass further compels many to opt for the latter.

Possible Solutions:

1. Choose Quality Over Price: Not all polycarbonate greenhouses are created equal. It’s crucial to differentiate between cheap models and those that are wooden-framed, which may offer more sturdiness and longevity.
2. Consider Size and Space: While 8×6 is a common size, it’s always advisable to purchase the largest greenhouse you can afford and fit into your space. A larger greenhouse not only provides more room for plants but can also offer more stability.
3. Opt for Second-Hand Glass Greenhouses: If you’re leaning more towards glass after considering polycarbonate’s challenges, second-hand options are worth exploring. Sites like eBay often list used glass greenhouses at highly affordable prices.
4. Maintenance: Regularly cleaning the polycarbonate panels can prevent or reduce clouding. Ensuring that the greenhouse is well-ventilated can also deter algae growth.

In conclusion, while polycarbonate greenhouses have their merits, it’s vital to weigh these against the potential challenges they present. Being well-informed and considering factors such as size, quality, and maintenance can help ensure that you make a choice that serves you well in the long run.
