Optimum temperature for cucumbers in the greenhouse

Growing cucumbers and tomatoes on a personal plot is quite a profitable business. Some gardeners work for profit, others for the soul and pleasure. Nevertheless, obtaining a plentiful harvest of vegetables depends on the growing conditions and proper care. The greenhouse is an ideal construction and assistant gardener. With not warm enough and a short summer period, it will help to maintain the desired temperature.

But here, you must follow the basic rules to create a favorable climate. Some vegetable crops, in particular cucumbers, do not tolerate sharp jumps in temperature. Because of this, the plants become sick, lag behind in growth and bear little fruit.

It is not enough for gardeners to know the optimum temperature for cucumbers in a greenhouse . You must be able to regulate it, despite the various weather conditions.

Greenhouse preparation

Preparation begins immediately after harvest. In the case of installing a new greenhouse, the soil needs to be prepared in the fall.

The earth is enriched with rotted manure and peat in equal proportions. The percentage of soil acidity that is not more than pH 7.1 is monitored.

It is necessary to choose the dimensions of the greenhouse correctly. Do not install too long views. It will be difficult to achieve good ventilation in them. Also, in cold weather, it will be more difficult to raise the temperature in the greenhouse for cucumbers .

Growing cucumbers in a greenhouse

Planting cucumbers is carried out:

• by seeds;
• seedling method.

The second method will allow you to get the crop earlier on average two weeks.

Cucumbers - the culture is rather tender and does not tolerate transplantation. The roots of the plant are shallow in the soil. Therefore, for seedlings, seeds are planted in peat pots.

The main temperature indicators for greenhouse cucumbers:

After the appearance of 4 leaves, seedlings are planted in a permanent place. The temperature of the soil by this time should not be lower than 18 degrees. Otherwise, the plant will not develop and grow. With prolonged low soil temperature, the seedlings will wither and die.

The optimum temperature for planting cucumbers

When emergence of cucumbers in the greenhouse, the temperature should be from 25 to 28 degrees. After the seeds have sprouted, enough 20-23 degrees. Excessive heat will entail excessive stretching of the sprouts. But good lighting seedlings are a must.

The night temperature regime in the greenhouse for cucumbers at the initial stage is set at 16-18 degrees. After a week, the night temperature is increased by an average of 3 degrees.

Air temperature in the greenhouse

What temperature should be in the greenhouse for cucumbers, depends on the stages of cultural development. For adaptation, the temperature is required lower than during periods of vegetation and fruiting.

Beginners should remember:

• lash growth slows at 15 degrees;
• at 10 ° C, growth ceases;
• temperatures below 9 degrees will destroy the plant.

It is necessary to create an optimal microclimate at all stages of growth, regardless of external factors. This approach will ensure the rapid growth of young shoots and abundant fruiting in the future.

To do this, the following rules are observed:

• in sunny weather, the temperature should be as high as possible;
• nightly figures depend on the previous day;
• at high temperature, increased humidity is required , at low, respectively, it decreases.

What temperature in the greenhouse for cucumbers is optimal , can be seen from the table.

For abundant fruiting, it is very important to maintain the temperature at night. The intensity of fruit growth directly depends on this. Ideal for the night is 21-23 degrees. Under such conditions, cucumbers bear fruit at full capacity. The duration of this process can lead to weakening of the lashes. Therefore, you need to give the plant time to recover. To do this, it is enough to lower the temperature at night to 18 degrees for a period of two weeks.

To avoid negative consequences, many gardeners install a temperature sensor in the greenhouse. Using it, you can monitor the climate as necessary and control unwanted temperature jumps.

Soil temperature in the greenhouse

Soil is the foundation of gardening success. Before landing, it should warm up evenly. The temperature in the greenhouse for cucumbers should hold at around 25-28 degrees for a week.

There are various ways to warm the soil:

• the use of organic fertilizers;
• heating using additional covering material;
• the use of various types of technical heaters;
• water heating around the perimeter.

Humidity in the greenhouse

Humidity, as well as temperature, is a rather important factor for the growth of cucumbers. Each period of growth, humidity indicators should change.

Seedlings require the lowest humidity, which ranges from 70-75%. During the period of active growth of cucumber lashes, the required humidity averages 90%. During flowering, it is reduced by 10-15%.

With a lack of moisture, the following processes may appear:

• plant growth is on the decline;
• increased risk for the spread of pests and diseases;
• the top of the soil dries out;
• the ovaries die.

Humidity in a greenhouse is not difficult to create. It is necessary to carry out regular watering of plants and soil, to monitor the temperature in the greenhouse. Humidity is very important for cucumbers, as they are 97% water.

Experienced gardeners recommend an evening watering of cucumbers in the greenhouse. In hot weather, morning or afternoon hydration is added. Whatever the temperature in the environment, watering should be carried out regularly and abundantly.

If you ignore the basic conditions for the care of cucumbers in the greenhouse, then a high risk of developing various diseases is created.

The main consequences of non-compliance with temperature and wet standards:

• the elasticity of the stems and foliage is lost;
• the plant turns yellow;
• various spots appear on the sheets;
• flower stalks fall or are absent;
• dried flowers and fruits of cucumber.

Having found the above signs in the greenhouse, you should immediately try to rectify the situation. Cucumber is quite moody and quickly dies.

Mixed landings

The greenhouse can be used rationally enough by applying mixed plantings.

It is worth considering that this is quite complicated. Humidity and temperature in the greenhouse for cucumbers and tomatoes should be different. Tomatoes cannot tolerate the humidity that cucumbers need, and vice versa.

Ideally, you need to have two greenhouses:

• moist and stuffy for cucumber plantings;
• hot and well ventilated for tomatoes.

Despite the difficulties, many gardeners practice mixed planting, trying in various ways to achieve a good harvest. Having gained some experience, you can achieve good results.

The main recommendations for greenhouse cultivation of cucumbers

When growing cucumbers in a greenhouse, you need to remember that temperature is the main indicator of the amount of yield.

It must be remembered that:

• planting is best done after the required temperature has remained at the same level for at least 5 days in the greenhouse;
• do not allow the soil to dry out;
• watering to carry out backward water under the root;
• Avoid sudden jumps in temperature in the greenhouse for cucumbers and tomatoes ;
• Drafts should not be allowed in the greenhouse with cucumbers;
• timely release the lashes from the fruit.

It is periodically useful to arrange a greenhouse bath. It is necessary to soundly water the greenhouse and close all the windows and doors. In the case of a mixed landing, the procedure is not worth doing.

Cucumber is a rather capricious culture. It is necessary to create the right ratio of moisture, heat and care. Do not forget about disease prevention. Make timely organic and mineral fertilizers. Subject to all the rules and subtleties, the greenhouse will become an indispensable tool in gardening.
