Greenhouse Warm Beds: DIY Guide

Hey everyone, and welcome back to my channel! Today, we’re going to be diving into the wonderful world of warm beds in greenhouses.

Whether you’re a seasoned gardener or just starting out, creating a warm bed can be a game-changer for your plants. It allows you to extend your growing season, get a head start on seedlings, and even grow some amazing heat-loving crops that wouldn’t normally thrive in your climate.

In this video, I’m going to walk you through the entire process of making a warm bed, step-by-step. We’ll cover everything from choosing the right materials to layering them properly and monitoring the temperature.

So, if you’re ready to learn how to create a cozy and productive warm bed in your greenhouse, then let’s get started!

Warm beds in a greenhouse offer a plethora of benefits for both the plants and the gardener. Let’s delve into some of the key advantages:

• Extended growing season: Warm beds effectively lengthen the growing season, allowing you to cultivate your favorite plants earlier in the spring and continue harvesting well into the fall. This translates to a more abundant and diverse yield.
• Improved plant growth: The consistent warmth provided by the bed promotes vigorous plant growth, leading to larger, healthier plants with increased yields.
• Reduced risk of frost damage: Warm beds offer protection against unexpected frost, safeguarding your precious plants from succumbing to the cold.
• Weed suppression: The heat generated by the bed effectively suppresses weed growth, minimizing the need for tedious weeding and saving you valuable time and effort.
• Water conservation: Warm beds require less frequent watering as the heat helps retain moisture in the soil, reducing water consumption and promoting sustainability.
• Enhanced soil fertility: The decomposition process within the warm bed releases valuable nutrients into the soil, enriching it and promoting plant health.

Warm beds come in various forms, each with its own heating method. Let’s explore some popular options:

• Compost beds: These beds utilize the heat generated by the decomposition of organic materials like manure, leaves, and straw. This method is cost-effective and environmentally friendly, but the heat output can be inconsistent.
• Electric beds: These beds employ electric heating cables buried within the soil to provide consistent warmth. This method offers precise temperature control but can be more expensive to operate.
• Hot water beds: These beds circulate hot water through pipes embedded in the soil, providing even heat distribution. This method is highly efficient but requires a more complex setup.
• Biofuel beds: These beds utilize the heat generated by burning biofuels like wood or pellets. This method is cost-effective but requires careful monitoring and fuel management.

Creating a compost layer is a crucial step in constructing a warm bed. Here’s a step-by-step guide:

1. Choose a location: Select a well-drained area in your greenhouse that receives ample sunlight.
2. Prepare the base: Remove any existing vegetation and level the ground.
3. Lay down a foundation: Spread a layer of coarse material like branches or logs to improve drainage.
4. Add organic matter: Pile on a generous layer of compostable materials like manure, leaves, and straw.
5. Moisten the layer: Water the compost layer thoroughly to initiate the decomposition process.
6. Monitor the temperature: Use a soil thermometer to track the temperature within the compost layer. Aim for a temperature between 100°F and 140°F.
7. Cover the layer: Once the temperature stabilizes, cover the compost layer with a layer of soil or mulch to retain heat and moisture.

By following these steps, you can successfully create a warm bed in your greenhouse, fostering a thriving environment for your plants and maximizing your gardening success.

The type of manure you choose will depend on the type of plants you are growing and the climate in your area. For example, if you are growing tomatoes, you will need a manure that is high in nitrogen. If you are growing in a cold climate, you will need a manure that is well-rotted and will not heat up too much.

Some common types of manure include:

• Cow manure: This is a good all-purpose manure that is high in nitrogen and phosphorus.
• Horse manure: This is a hot manure that is high in nitrogen. It is best to use it in the fall or winter so that it has time to decompose before planting.
• Chicken manure: This is a very high-nitrogen manure that should be used sparingly. It is best to compost it before using it in your garden.
• Pig manure: This is a hot manure that is high in nitrogen and phosphorus. It should be composted before using it in your garden.

If you have access to animals, you can make your own manure compost. To do this, simply collect the manure and pile it up in a sunny spot. Turn the pile regularly to aerate it and keep it moist. The compost will be ready to use when it is dark brown and crumbly.

• When laying manure, it is important to spread it evenly over the bed.
• You should also water the manure well after you have spread it.
• If you are using fresh manure, it is important to let it compost for at least six months before using it in your garden.
• You can also add other organic materials to your manure compost, such as straw, leaves, and grass clippings.
• Manure is a great way to add nutrients to your soil and improve its drainage.

There are a few different ways to heat a greenhouse with a polycarbonate design. One option is to use a heating cable. Heating cables are typically laid on the ground beneath the plants. They can be plugged into an outlet and will provide warmth to the plants.

Another option is to use a hot water system. Hot water systems circulate hot water through pipes that are laid beneath the plants. This is a more efficient way to heat a greenhouse, but it can be more expensive to install.

Finally, you can also use a solar heating system. Solar heating systems use the sun’s energy to heat water, which is then circulated through pipes beneath the plants. This is a very environmentally friendly option, but it may not be as effective in cold climates.

Heating cables are a popular choice for heating greenhouses because they are relatively inexpensive and easy to install. They can be laid on the ground beneath the plants or buried in the soil. Heating cables should be plugged into a thermostat so that they only turn on when the temperature falls below a certain level.

There are many different types of heating cables available on the market. Some of the most popular brands include:

• Heat Mat: Heat mats are a type of heating cable that is designed to be laid on the ground beneath plants. They are typically made of a thin, flexible material and are easy to install.
• Thermostatically Controlled Heating Cable: Thermostatically controlled heating cables are a type of heating cable that is plugged into a thermostat. The thermostat will turn the cable on and off as needed to maintain a desired temperature.
• Self-Regulating Heating Cable: Self-regulating heating cables are a type of heating cable that automatically adjusts its output based on the temperature of the surrounding environment. This means that they will not overheat, even if they are covered with soil or mulch.

When choosing a heating cable for your greenhouse, it is important to consider the size of your greenhouse, the type of plants you are growing, and your budget. You should also read reviews of different brands and models before making a decision.
