Which greenhouse is most effective?
Glass to ground is better for crops grown on the greenhouse floor such as tomatoes and cucumbers. It gives more growing height and gets light right down to the base of the plants. Insulation is usually less so it costs more to heat in winter. Avoid tall trees It’s not a good idea to place a greenhouse underneath any tall trees as they greatly reduce the amount of sunlight that reaches your plants. This is made even worse when the glass gets dirty from bird droppings and sticky pollen.
What are the disadvantages of polycarbonate greenhouses?
Polycarbonate panels can scratch more easily than glass, and over time, they may yellow or become cloudy, reducing light transmission. While they are more affordable than glass, they are more expensive than plastic greenhouses. Glass greenhouses are preferred for their traditional aesthetic, longevity, direct light transmission, and environmentally sustainable nature. Polycarbonate greenhouses are preferred for their cost-effectiveness, thermal insulation properties, impact resistance and light diffusion.While polycarbonate can break under extreme conditions, it’s one of the most durable thermoplastics available. It offers 250 times the impact resistance of glass and 30 times that of acrylic, making it highly resistant to breakage under normal use conditions.It’s even more durable and damage-resistant than acrylic, so if longevity is your main priority, either for a new project or for an existing greenhouse repair, this is the material to choose. Over 200 times stronger than standard glass, polycarbonate is almost unbreakable, making it ideal for greenhouse glazing.However, there are also some cons to consider when choosing between glass or polycarbonate. Polycarbonate panels can scratch more easily than glass, and over time, they may yellow or become cloudy, reducing light transmission. While they are more affordable than glass, they are more expensive than plastic greenhouses.
