Nutrients are necessary for the development of a herb and there are many factors that affect the absorption of these nutrients. One of the most crucial factors is temperature. The temperature in your grows room is crucial for the photosynthesis of your herb. The climate of your grow room must be controlled and consistent for you to be able to yield great quality herbs. An example would be low temperatures that reduce evaporation on the leaves, thus decreasing the ability of the roots to absorb nutrients. The remaining nutrients would eventually disintegrate in the root environment and become waste. Some people think that this is a minor imperfection, but ignoring this element can have serious consequences in the entirety of the plant as a whole. Therefore, it is very important to create a controlled environment in your grow room. This article will explain what the ideal temperature a herb needs, and what you can do to control these temperatures.
Let’s start with the location of your grow room. The recommended location would be the basement for it is a lot cooler than in an attic with a flat roof. Aside from the location; the size, airflow, lighting, and the extraction rates are important factors. Keep these in mind when building your grow room. To start off, measure the temperature of your grows room with a thermometer. Analog and digital thermometers do fine. A digital thermometer with a built-in memory system is also useful in keeping track of the maximum and minimum temperatures that occurs in the room while you are gone. Always measure the temperature at various areas in your grows room including the areas covered with shade. Next, add in some fans to provide good air flow. Remember that these herb need to breathe too. To provide a little radiance, place some lamps. The lamps emit radiant heat which affects the air temperature. You have to be cautious not to put your plants too near the lamp. This will cause the plant to dry up which in turn would not yield a good quality product. Heat often becomes a problem in your grow room due to the fact that the lamps used produce a lot of heat.
The dimensions of the room are important. You should be wary not to put too much lighting that the heat would be fatal to your plants. When the light is turned on, an ideal temperature for the plants is between 68ºF and 77ºF (20ºC and 25ºC). As the plants mature, their rate of evaporation increases and the temperature can increase to a maximum of 82ºF (28ºC). The temperature should lie between 62ºF and 72ºF (17ºC and 22ºC) when the lights are off. Another important rule is that the temperature differences between day and night cannot be too high, with only a maximum difference of 10ºC. So the temperature can’t go below 64ºF (18ºF) at night when it’s 82ºF (28ºC) during the day. A temperature difference of 5ºC is best. LED lights are ideal alternatives to help keep the temperature lower in an indoor grow room. In dealing with hotter climates, installing an air conditioning unit would also be an option to keep your plants cool. Installing an extractor fan will blow the hot air outside and suck in fresh air from the outside.
Keep in mind that the distribution of airflow is also important so the temperature spreads evenly within the room. Swivel fans should suffice in circulating the air inside your grow room. Fresh air from the outside should also be well distributed over the growing area so that there won’t be any cold spots. During colder weathers, a simple space heater with a thermostat is usually sufficient enough to heat your room. A radiator with a thermostat would also be an option. Lastly, constant monitoring will ensure you with great results and products that can’t be matched.
