Choosing a humidifier for your indoor grow space

Environmental conditions play a vital role in successful indoor cannabis grows. It goes without saying that the right temperatures are essential for growing healthy plants, but if you want to further optimize your indoor growing space, you shouldn’t ignore the importance of relative humidity in relation to the plant’s life stage.

The right humidity levels allow a faster plant development, which translates into shorter growing periods, but also into healthier plants thanks to better nutrient absorption and assimilation. It’s a great way to make the most of your indoor setup and get maximum yields.

What type of humidifier should I get?

As you can see in Alchimia’s catalogue, there are different types of humidifiers. From classic models, perfect for small/medium-sized DIY grows and maintaining good conditions for rooting clones, to units designed for larger spaces that can be directly connected to the water tap.

Ultrasonic humidifiers: ideal for grow tents
