Getting informed on what temperature should I keep vegetable plants in polytunnel is a good question from each gardener in the UK. First and foremost, the mini polytunnel refers to the polytunnel that will let you expand the plant growth season beyond the usual timeframe.
It protects the seedling when the so-called ambient temperature changes and decreases further down and overnight. It is the task of the polytunnel to conserve the heat, allowing the soil to keep moist and hydrated, thus protecting the UK garden from animals and pests. The best ones also temper weed growth in the greenhouse.
The Ideal Temperature In The Small Polytunnel
With this said, what temperature should I keep vegetable plants in a polytunnel? Remember that the warm, direct light from the sun not needed for your crops in the category of the cold season in the UK. Vegetables in the warm season category, including peppers and cucumbers, can thrive in the daytime temperature in the polytunnel at 29 degrees Celsius in the day and 18 degrees Celsius at night.
However, your warm-season crops or vegetables require brighter lighting.
How Cold Can Plants Tolerate In A Polytunnel?
Your crops in the polytunnel one may subdivide into three different categories. These are:
- Cold-tolerant vegetables
- Cold-temperate vegetables
- Cold-sensitive vegetables
These veggies are crops with the base range of temperature at four degrees Celsius and are required to be grown with the average temperature daily at 18 degrees Celsius.
It may be challenging to determine their characteristics from the name alone, but you reasonably have the idea, right? Cold temperate veggies are those with the base range of seven degrees Celsius and generally at the ADT of 21 degrees Celsius.
Your cold-sensitive crops are those with eight degrees Celsius or even higher and cultivated at the ADT of 24 degrees Celsius at the most.
When thinking about managing the temperature at the greenhouse, it is significant to consider how the growth of the plants and the way they develop are influenced by the various growth stages. They constitute:
- Germination of seeds
- Vegetative stage
- Reproductive phase
- Ripening of the plant or crop
The optimum temperature of the plant can change when it grows from the seedling toward maturity. In general, germinating seeds and early seedling growth happen rapidly in warmer climates that may usher into respiration and photosynthesis.
You can also favour this with temperatures and growth among younger plantations since there seems to be less tissue by the roots and stem when in comparison with the rest of the plants.
How Do I Protect My Plants In An Unheated Greenhouse?
You have encountered bubble wrap in many gardening tips in the UK, and this is precisely what you need to use when layering what’s inside the greenhouse. The sunlight required is still part of it, but this layer to protect shall keep the plantation safe during the night.
Moreover, what kinds of protection are present with the heaters? Aside from the bubble wrap, you can add one to two layers of fleece to the crops. And after this, you can add the wrap around the pots to help with the insulation and prevent the clay containers from cracking down.
You can also layer the bubble wrap within the greenhouse. The sunlight you need can come through, but the additional protective layer will be present to keep the crops safer during the night.
What Temperature Should A Polytunnel Be At Night?
An interesting question we have here, and the answer shall help you get better crops too. In any greenhouse, may this be your commercial greenhouse or the mini greenhouse, the ideal temperature should be 24 degrees Celsius at night (32 degrees Celsius in the daytime).
It depends on the crop type for the vegetables, but growing the crops at the lower range can provide optimal results. Plants can offer more branches and floral buds compared with the plants that have grown in warmer temperatures.
Gardening in the United Kingdom should be fun and easy. If there are obstacles along the way, there are tools and advice to help you move forward.
The mini British garden or the small polytunnel is among the most lucrative greenhouses that can house many herbs, veggies, and berries. You can also cultivate several herbs, cabbage, cauliflowers, cabbage, beets, onions, radish, and more. The limitations are with your spaces. On the other hand, you can also control the farm-to-table crops that you want to get onto your table with the steps.
The crops can produce the healthiest recipes, and you can also pursue them in the market for profiteering.
