Temperature for a tomato in a greenhouse: how to plant seedlings in a greenhouse, optimal conditions for tomatoes and soil

temperature for tomatoes in the greenhouse - the factor, which determines the conditions of growth and development of tomato If tomatoes are grown in a greenhouse or a greenhouse, it is necessary to create all conditions for a comfortable growth. Tomatoes grow well if they have enough light and heat, the soil is well moistened( but not re-poured), there is an influx of fresh air and the room is set at a temperature at which plants can develop. When all these conditions are met, tomatoes will be poured with juice, and yield a good harvest.

options: at what temperature to plant tomatoes in the greenhouse

Any vegetable growing and developing well, if it is in aOmfortnyh for themselves conditions. Especially important is the temperature regime for plants.

Tomatoes are very thermophilic plants that are "afraid" of temperatures below 16 degrees. Therefore, among the growth of several different cultures in the greenhouse, it is desirable to separate them from each other by partitions and to establish for each species its optimal regime.

should know that during the various phases of cultivation of tomatoes require different modes:

• To seeds normally grow, you need to keep warm at least 22 and not more than 25 degrees;
• And here about 7 days after the seedlings are planted, it should be tempered and set the temperature regime within the range of +16 - +18 degrees.

Comfortable temperature for tomato in the greenhouse should be below 16 degrees

Regarding humidity in a greenhouse or glasshouse, it should be in the range 60-70%.

During the planting of shoots, attention should be paid not only to the temperature of the air, but also to how warm the upper layers of the soil are. Before you start planting tomatoes, it's best to make sure that the temperature is at least +15 degrees. In this case, the seedlings will easily settle down. If the soil temperature is below +10, there is a danger that the roots of the plant can rot and disappear.

You can not plant tomatoes during freezing, even if the temperature is only -1 degrees. The most frost-resistant varieties can withstand about 3 degrees below zero, but only for a short time.

Optimal temperature in the greenhouse for a tomato

Tomatoes are related to heat-loving plants. Even the slightest cold can turn out bad for them. To avoid this, an optimal temperature is required at each stage of tomato germination.

So, the temperature regimes under which it is recommended to grow tomatoes:

• After the seedlings are in the ground, the temperature in the greenhouse should be kept around + 15-16 degrees, and then gradually increase it;
• When the temperature rises to + 25 degrees, it will be seen that the seedlings started to grow well;
• So that the plants do not get too bulky and stretched, the temperature should be lowered again to + 16-17 degrees.

It should be understood that the temperature drop in the greenhouse is below 12 degrees or its increase is more than 30 at the time when the plants start to bloom, causing the flowers to fall off and the formation of a further ovary to cease. The fact is that the low temperature regime does not give the necessary heat for the ripening of pollen, but the high one makes the ovary empty.

Tomatoes - heat-loving plants, so maintaining a comfortable temperature is very important for them

The conditions of temperature below +5 degrees tomatoes begin to feel uncomfortable, and then die. Too warm soil is also harmful to a tomato.

If the greenhouse has a constant temperature above +35 degrees, sometimes reaching a mark of +40 degrees, the plants will die from the heat. In this case, you need to quickly ventilate the room, open all possible windows and other structures. Humidity should be no more than 65%, and soil - 80%.

When removing the first fruits, the air heating should be reduced to + 16-17 degrees. This is necessary to lower the growth rate of foliage and thereby increase the filling of tomatoes.

Comfortable temperature in the greenhouse for tomatoes: how

adjustment Sometimes it happens that the weather surprises and they are not always pleasant. Typically, in the spring and autumn period, the temperature often skips and it is necessary to save the crop, to additionally heat the hotbed or vice versa to cool it.

It has proven method for increasing the temperature in a greenhouse or glasshouse, include:

• If greenhouse consists of a film, it is possible to add one additional layer of this material, which would create a "cushion" of air trap heat;
• Covering the greenhouse or the roof of the hotbed with a special cover material - spunbond will also help raise the temperature inside the room;
• If you want to water some plants before the expected frosts, this will help to keep the heat, although you need not forget to ventilate the greenhouse by day;
• In the cold period, you can install another mini-greenhouse - directly above the plants themselves;
• You can simply cover a small greenhouse or a hotbed with warm clothes or rags.

For good growth of tomatoes in the greenhouse must be airing

If the walls of the greenhouse to form strong condensate urgent need to ventilate the entire room, otherwise the plants will not survive on the very high humidity.

Sometimes it happens that the temperature should not be increased, but, on the contrary, lowered. How can this be done?

There are several ways:

• maximum ventilation - offers all that is possible and thereby the temperature drops to 8 - 10 degrees;
• Abundant morning watering can reduce the overall climate in the greenhouse.

By the way, remember that the leaves of tomatoes can not be watered in any case. Otherwise, it will lead to the formation of burns on their surface.

Temperature conditions of growing tomatoes in the greenhouse

intense heat as the cold adversely affect the development and growth of tomatoes. The conditions for growing these crops should be such that the plants will feel comfortable. Only in this case it is possible to hope for a plentiful harvest.

The tomato can withstand a very strong rise in temperature to 40-42 degrees, but only if such heat will be 1-2 days, no more.

During the hot summer, especially in southern regions it is often necessary to ventilate the greenhouse, but it is best to keep the window and door open.

In very extreme heat can and should open windows and doors for provetirvaniya

But not only the temperature of the air is important:

• primer should be 14-16 degrees cooler +;
• Water, which watered the plants - do not fall below the mark at +16 degrees( ideally 20-22).

With very strong heat it is possible to cover the walls of a greenhouse or a hothouse with a solution of chalk at the rate of 2 kg per bucket of water. For efficiency, 300 ml of milk can be added. After the heat subsides - the coating must be washed off.

Properly selected temperature in the greenhouse - one of the main factors that will gather a good harvest. If the climate presents surprises, the temperature regime will have to be regulated independently. You can certainly buy additional equipment for automatic regulation, but if it gets in the pocket, it remains to achieve the desired temperature more simple and cheap way.
