As the temperature drops at night, you might want to know how to keep your polytunnel warm at night. It’s necessary to keep your plants warm to protect them from frost or freezing temperatures. However, the rising energy expenses and environmental effects may prevent you from adequately heating your polytunnel.
This article will give you several tips on how to keep your polytunnel warm at night without having to spend a fortune.
How Can You Keep Your Polytunnel Warm at Night?
Add compost in your polytunnel
Compost is naturally warm, so it makes sense to keep them inside your polytunnel. Good compost can be as hot as 100 degrees F. It can keep your polytunnel warm throughout the night, especially if you regularly turn it to add oxygen. Additionally, having wood mulch as pathways can contribute to the heat.
Use thermal mass objects
If you solely rely on the sunlight to heat your polytunnel, you need thermal mass objects to increase warmth further. Bricks, clay, rocks, concrete slab floor – these objects absorb heat during warm weather and release it when the atmosphere is cold.
Using thermal mass objects is one of the most affordable ways to heat a polytunnel. If you’re planning to make raised beds, use stone or bricks for maximum heat absorption. Water is an excellent thermal mass as well. It’s also a great idea to put black barrels or water around your polytunnel.
Strategically position your heaters
If you have heating systems, make sure to put them in an open spot at a corner of your polytunnel. Keep them away from water for safety purposes. Additionally, angle the heater above the plants that need it most.
Only heat the necessary areas
You don’t have to heat your entire polytunnel if you don’t need to. You can create a mini polytunnel inside your polytunnel. Further insulate your mini polytunnel by placing bubble wrap, your heating system, or horticultural fleece.
Why Should You Buy a Mini Polytunnel?
