- Most popular: Polyethylene Plastic is the most commonly used material for greenhouse coverings, and for good reason. It has a great balance of affordability, durability, and versatility.
- Personal experience: Having built and maintained multiple greenhouses, I have found polyethylene plastic to be the most reliable and effective choice for maintaining the optimal growing environment.
- Polycarbonate: While polycarbonate is also a popular option, it tends to be much more expensive than polyethylene plastic. It also doesn’t provide the same level of insulation and UV protection, which is important for plant growth.
- Woven Plastic: Woven plastic is a unique option that has the advantage of being able to withstand hail and other harsh weather conditions. However, it can be more difficult to install and won’t provide the same level of insulation as polyethylene plastic.
- Reinforced Polyfilm: For those looking for an extra durable option, reinforced polyfilm is a good choice. However, it is also more expensive and may not be necessary for all DIY greenhouse projects.
