Growing indoors requires artificially reproducing optimal conditions for plant development. This not only means ventilation, but also actively measuring and adjusting variables such as temperature, humidity, and CO₂ levels. A stable environment allows plants to grow without stress, better absorb nutrients, and develop denser, more resinous buds.
In this category, you will find tools to measure, regulate, and automate the microclimate of your room or grow tent:
Because small variations in temperature or humidity can have a major impact on plant health. An environment that is too hot or dry can stunt growth or reduce production. Conversely, high humidity during flowering can lead to dangerous fungi such as botrytis. With the right sensors and controllers, you can react quickly or automate the entire process.
This category is useful for indoor growers looking for stability and professionalism, whether in compact grow rooms or larger spaces. If you want to improve the quality of your harvest, reduce risks, and eliminate the hassle of manual control, you'll find the tools you need here.
At Alchimia, we work with specialized brands such as Cornwall Electronics, GSE, Cli-Mate, VDL, and Garden HighPro, among others. Some of our most highly rated products include:
During growth, the ideal temperature is 22-26°C and 60-70% humidity; during flowering, the temperature is maintained, but humidity is lowered to 40-50% to prevent fungus.
Yes. With complete climate control units, you can program and manage temperature, humidity, and ventilation from a single device, even connecting multiple appliances.
