1. Increase insulation<\/span><\/h2>
Insulation passively heats a greenhouse; rather than adding more heat, increasing insulation minimizes heat loss. While you can insulate the whole greenhouse structure itself, you can also focus on insulating the soil or individual plants. As long as the plants are at the right temperature, you can forgo insulating or heating the rest of the greenhouse.<\/p>
Here are some ways to insulate your greenhouse, soil, or plants:<\/p>
- Use bubble wrap<\/li>
- Recycle fall leaves<\/li>
- Add mulch<\/li>
- Cover your plants<\/li> <\/ul>
Use bubble wrap<\/span><\/h3>
If you have a bunch of bubble wrap lying around, you can use it to insulate your greenhouse. Simply wrap the inside walls of the greenhouse in bubble wrap. So, the next time your Amazon package comes with a questionable amount of bubble wrap, keep it around for the winter months.<\/p>
Recycle fall leaves<\/span><\/h3>

There\u2019s a cheap \u2014 even free \u2014 alternative homeowners like you can use: fallen leaves. Bags of fall leaves can be reused as insulation<\/a> by pilling them up against your greenhouse walls.<\/p>
Add mulch<\/span><\/h3>
Among the many benefits of mulch<\/a> is the insulation it provides for your soil. Mulch helps keep the soil (and your plants) warm and toasty throughout the wintertime.<\/p>
Don\u2019t think you need to spend money on fancy mulch, either. You can find free mulch<\/a> even in your own backyard, such as fall leaves, grass clippings<\/a>, or old paper products.<\/p>
Cover your plants<\/span><\/h3>

Greenhouse plants can be covered in horticultural fleece (also known as gardening fleece), row covers (typically made of clear plastic), or cloches. The latter can be recycled drink bottles, old milk containers, or even mini greenhouses (hotboxes).<\/p>
2. Add thermal mass<\/span><\/h2>

Increasing your greenhouse\u2019s thermal mass is as simple as adding more materials with a high thermal mass. These materials are heat sinks that trap the sun\u2019s heat in the morning and release it throughout the night.<\/p>
Water, soil, clay, stone, bricks, and ceramics are some materials with high thermal mass that homeowners can easily find. Here are some ways to integrate them into your greenhouse:<\/p>
- Place barrels or tanks of water, preferably black ones for maximum heat absorption, in the corners and along the north wall of the greenhouse. If you don\u2019t have much space, even small jugs of water can help.<\/li>
- Add brick or stone paths and edging. This not only adds thermal mass but also adds style.<\/li>
- Store extra bags of soil inside your greenhouse.<\/li> <\/ul>
3. Make compost<\/span><\/h2>

So, making compost<\/a> inside can help keep your greenhouse warm in the winter; as a bonus, you\u2019ll also get black gold to use in your garden. You can simply dig a trench and make a compost pile, but making a hotbed is a more useful and more aesthetically pleasing option. <\/p>
Used to start seedlings in the winter, a hotbed is a raised garden bed that\u2019s filled mostly with composting materials topped with a growing medium (such as soil). Aim for a hotbed at least 20 to 30 cm deep and maintain a 3:1 ratio of compost to soil. You\u2019ll also need a good ratio of greens to browns. You can cover your hotbox with a cloche, row cover, or even an old window pane if you want even more heat.<\/p>
If you don\u2019t want to make anything, you can simply use a compost bin. We have a list of the best compost bins<\/a> that you can check out for ideas.<\/p>
4. Add a heating system<\/span><\/h2>

There are many sources of fuel, such as wood, coal, natural gas, propane, kerosene, electricity, and renewable energy (including solar energy). <\/p>
They can be used to power these types of heating systems:<\/p>
- Electric room heater<\/li>
- Hot water heating system<\/li>
- Unit heater<\/li>
- Radiant heater<\/li>
- Stove<\/li>
- Ground-to-air heating system<\/li>
- DIY small heater<\/li> <\/ul>
Just make sure that the heat isn\u2019t stuck in one place; you\u2019ll need airflow to move the heat around. If you don\u2019t, moisture might build up and invite mold into your greenhouse.<\/p>
Some heating systems are better installed before you set up your greenhouse. Otherwise, you may need to tear up some parts of the structure to accommodate elements of the heating system.<\/p>
