Cannabis can grow well in moderate conditions, but weed plants truly produce the maximum yield when the environmental conditions are controlled. Cannabis plants cannot survive cold and can often get destroyed, especially varieties that are grown indoors. The plants perform the best when they are kept around 70-85 degrees Fahrenheit.
An important point in this regard is that the plant thrives when there is a clear temperature difference in the vegetative phase and the flowering phase. The early growth of the cannabis plant occurs well, in humid conditions and higher temperatures. These conditions are able to quickly accelerate the initial growth of the weed plants.
The same conditions are not viable for good growth, when the plant enters the flowering phase. The marijuana containing buds only grow well, in reduced humidity and much cooler conditions. Ideally, your plants should be ten degrees cooler than their vegetative stage.
Freezing temperature can kill the plant and at least completely stop the growth of the plant. When combined with dampness, the pot plants are attacked by mold and get completely destroyed. Marijuana plants also lose their ability to perform photosynthesis, which is a must for plant growth.
High temperature is also not good for marijuana plants. Although these plants can survive warm conditions, they cannot grow at their normal speed and produce low yield. The temperature needs to be therefore controlled, and this eliminates problems, such as nutrient burn and mildew. Higher temperatures destroy the flavor of the cannabis buds, and alter their characteristic chemicals.
Humidity refers to the presence of water vapors in the air. It is often expressed as a percentage of the maximum humidity possible at a particular temperature. The measurement is termed as relative humidity (RH). The required RH values keep going down as the marijuana plants move from their initial growth stage to the final stage.
The ideal use of humidity ensures that a 10% decrease in RH values occurs with every successive stage of cannabis growth.
Another important aspect in growing healthy weed plants is to provide ample ventilation. Ventilation is essential for maintaining the actual humidity levels near the plant leaves and ensuring that there are no dew drops that form on the leaves, therefore stopping the intake of air. Cannabis plants grow well when they are able to receive fresh air, and produce the highest quality buds.
It is essential to reduce humidity when the pot plants enter the flowering stage. Buds need lower humidity levels (<40% RH) to ensure that they develop the required smell and flavor. Some pot growers also use additional carbon dioxide (CO2) to ensure that the cannabis plants grow to their full potential.
Ventilation is essential for a number of reasons. Not only is it required to protect the cannabis plants from the attack of molds, it is also essential to ensure that you grow weed in a secluded manner and do not disturb the neighbors.
Carbon scrubbers (filters) are used in this regard and should be employed to filter out the exhaust air. This means that it is essential to create an efficient exhaust system for your weed growing area.
