When it comes to choosing the best cover for a low tunnel, there are a few options to consider. Two popular choices are floating row fabric and thick-mil clear plastic sheeting. Both have their advantages and can create a mini-greenhouse environment for your planting beds.
Floating row fabric, also known as row cover or frost cloth, is a lightweight fabric that is typically made from spunbonded polypropylene. It is designed to allow air, light, and water to penetrate while protecting plants from frost, insects, and harsh weather conditions. This type of cover is easy to install and can be laid directly over your plants or supported by hoops or frames. It provides some insulation and can extend the growing season by a few weeks.
One of the benefits of using row cover is its breathability. The fabric allows air circulation, preventing heat buildup and reducing the risk of plant diseases. It also provides some shade, which can be beneficial in hot climates or during periods of intense sunlight. Row cover is also lightweight and easy to handle, making it convenient for gardeners of all skill levels.
On the other hand, thick-mil clear plastic sheeting offers a different set of advantages. This type of cover creates a more enclosed and insulated environment for your plants. The clear plastic allows sunlight to pass through, creating a greenhouse effect and trapping heat inside. This can be particularly beneficial in colder climates or during the early spring when temperatures can still drop significantly.
Clear plastic sheeting is also effective at protecting plants from wind, rain, and pests. It provides a barrier that helps retain moisture and creates a microclimate that promotes plant growth. However, it is important to note that clear plastic can also trap excess heat on hot days, so proper ventilation is crucial to prevent overheating.
When choosing between row fabric and clear plastic, consider the specific needs of your plants and the climate in your area. If you are primarily concerned about frost protection and insect control, row cover may be the better option. However, if you want to create a warmer and more enclosed environment, clear plastic sheeting might be more suitable.
In my personal experience, I have found success using both types of covers in different situations. For early spring plantings, I have used clear plastic sheeting to create a warm and protected environment for tender seedlings. This has allowed me to start my garden earlier and extend the growing season. On the other hand, for crops that require more airflow and protection from insects, I have used row cover with great results.
Ultimately, the best cover for your low tunnel will depend on your specific needs and preferences. It is worth experimenting with both options to see which one works best for your plants and growing conditions. Whichever cover you choose, make sure to properly secure it to prevent damage from wind or pests. Regular monitoring and adjusting of the cover will also be necessary to ensure optimal growing conditions for your plants.
