Techniques On Heating Greenhouse

People often say, “As long as the sun is rising, there is hope.” And yes, as a fellow garden enthusiast, I am here to say that as long as the sun shines, there are a lot of techniques we can incorporate in keeping our plants warm enough.

Make sure your plants obtain an adequate amount of light. Eliminate any material that would prevent your plants from getting enough light and consider cleaning the glass to maximize available light.

If you’ve accomplished these things already, then let us proceed with the techniques. Below are some of the tips that you can utilize to keep your unheated greenhouse warm during winter.


#1 Outer Covering

Consider covering all parts of the unheated greenhouse with a single layer made of plastic to maximize the light input.

Although utilizing two layers of plastic and blowing air into the space between them guarantees more protection from cold, it prevents the greenhouse from acquiring an extra ten percent of possible light.

In addition to this, purchasing another layer of plastic and purchasing an electric blower to inflate the layers are costly.


#2 Double covers

In an experiment comparing an air-inflated greenhouse and an unheated one with only a single layer, garden enthusiasts have obtained a valuable conclusion.

In the experiment, the temperature data obtained show that night time low temperatures with a mean of 4˚ F (2.2˚ C) are warmer in the air-inflated house compared to the unheated house single-layer outer covering.

For instance, during the night, when the low temperature was –8˚ F (–22˚ C) outside, the temperature decreased to 20˚ F (–7˚ C) under the inner layer of row cover and 2˚ F (–17˚ C) inside a single-layer house.

In conclusion, the temperature in the air-inflated greenhouse was 7˚ F (–14˚ C). Meanwhile, under the row cover’s inner layer, it was 24˚ F (–4° C).

The observations made during the trial created some remarkable comparisons between the two houses.

Although there are no apparent differences in the quality of crops, the duration regarding the seedlings’ growth was faster in the air-inflated greenhouse. In addition to this, the air-inflated house also warmed quicker.

Therefore, double-covering the unheated greenhouses is advised because it speeds up the growth of the seedlings.


#3 Inner layer

There are a lot of options when it comes to inner layering. But we have to choose the best one. You can always make little tunnel greenhouses within larger ones; and yes, this method is still employed by some of our Japanese farmers.

However, we have to know our limits. Is placing tunnel greenhouses efficient in space? Are the methods of its ventilation and management easy?

The answer is no. How about motorizing the night-curtain systems? Although this method employed in reflective materials and is effective in greenhouses, we have to weigh our budget.

Doing this method is very costly. Then what should we do? Well, lucky for you, we have the simplest and most cost-effective option in store for you.

Allow me to present the most affordable choice- a floating row cover. Although the floating row covers are less protective against the cold than glass frames, it has a self-ventilating nature.
