A proper temperature of the environment can increase yield by 20%-50%. Extreme temperatures decrease yields

Plants’ reaction to periodical temperature changes (changes in growth and development) is called thermoperiodism  

A change in day’s temperature is good for plants:  higher at day time and lower at night.  An optimal day and night temperature difference for temperate zone plants is 5 - 7 °С,  for tropical plants - 3–6°С   

All plants depend on temperature the same way: higher temperature speed up all chemical and biological processes, but too high temperature slows down and then stops the processes

Optimal temperature for root zone is lower

Low temperature can cause seed germination. Jumps in temperature can damage buds and formation of flower knobs

Besides, temperature influences many processes dependant on photosynthesis. Some plants can be stimulated for flowering by daylight hours changes and by lower night temperature

It is still not clear why the temperature more than 30C is harmful for most of plants. It is supposed that the reason is the misbalance of production and absorption of nutrients. It is known that at lower temperatures plants produce more unsaturated fats with lower fusion temperature, and vice a versa. On the other hand, at higher temperatures building cells, necessary for growth, are quickly destroyed or produced not enough. Anyhow maximum and minimum temperatures have a negative impact on plants’ development

To control temperature automatically non-stop we have designed our special device SensiRoom 2x-t 


The device can control active ventilation. In case the absorbed air is cooler than the air masses in the room, the active ventilation will lower the temperature around plants. The device is also able to turn on some heating device or air-conditioner if necessary
