Is An Unheated Greenhouse Frost-Free Or Not

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.

 

Crops To Plant During Winter

Is it possible to grow plants during winter? Well, I would like to quote what Audrey Hepburn once said, “Nothing is impossible.”

There are a lot of plants that you can grow during the winter season. Here are some of the following:

  • Garlic
  • Leeks
  • Onions
  • Radishes
  • Lettuce
  • Peas
  • Potatoes
  • Swiss chard and other greens

 

Conclusion

Is an unheated greenhouse frost-free? Are you worried about your plants not making it through the winter? Are you anxious that you might not be to grow plants because of the cold weather? Are you scared that your unheated greenhouse might not be frost-free?

Well, worry no more because we’ve got the best solution for you! The key? It’s layers.

Through this guide, you will be able to make your unheated greenhouse frost-free without even worrying about the expenses. The methods presented in this article are comprehensive and one hundred percent cost-effective.

Now prepare your layers because, for the first time in forever, you’re about to thaw a frozen greenhouse. Always remember, the plant that grows in adversity is the most beautiful and rare of all. Good luck and best wishes!

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.

 

What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.

 

What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.

 

Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.

 

What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.

 

3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.

 

Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.

 

Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.

 

Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.

 

Conclusion

No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
