How does a humidifier work?
All humidifiers can increase the relative humidity level in the environment. However, the systems used to achieve this vary:
- Hot steam – heats water into steam and releases it into the environment
- Cold mist – disperses water at room temperature using a fan
- Ultrasonic – Atomizes water into small particles using ultrasonic vibrations.
What level of humidity does an indoor crop need?
Plants require different levels of humidity depending on their stage of development:
- Germination and seedling phase: Young plants need high humidity (70-80%) to promote their initial development.
- Vegetative phase: Moderate humidity (50-70%) helps plants absorb nutrients and develop robust foliage.
- Flowering phase: A lower humidity level (40-50%) prevents fungal diseases and ensures flower health.
Inadequate humidity levels can affect plant health:
- Too low humidity: Leaves close their stomata (pores), limiting CO₂ absorption and slowing photosynthesis. Dry air also encourages the growth of pests such as spider mites.
- Excessive humidity: Can cause mold growth, especially during the flowering phase.
If the crop has excessive relative humidity, a dehumidifier can be used to maintain it at optimal levels.
Controlling the climate of your indoor grow room with a humidifier
For this reason, Alchimia offers a range of humidifiers, with different power levels depending on the humidity level required and the size of your growing space, to help you recreate the ideal environment for your plants.
Among the available models, we highlight the following categories:
- Ultrasonic humidifiers: Like the Mist Maker (with 1 to 5 membranes), they produce a fine mist using ultrasonic vibrations. They're ideal for increasing humidity in small spaces or medium-sized grow tents. The 5-head model, for example, is suitable for larger needs.
- High-capacity humidifiers: The Monzón model (with 12 membranes) is designed for large surfaces or open-plan rooms. It can be connected to a water source, avoiding frequent refills, and has a humidification capacity of 5.5 L/h, perfect for maintaining high humidity in large facilities.
- Models with built-in humidifier: Some humidifiers, such as those from Garden HighPro, include a humidifier that automatically regulates the humidity level according to the specific needs of the plants.
With this equipment, you can optimize your growing environment and maximize its results.
Frequently Asked Questions about cannabis humidifiers
What humidity level is ideal for each phase of cultivation?
- Cuttings and seedlings: 70-80%
- Vegetative growth: 60-70%
- Flowering: 40-50%
However, keep in mind that the ideal humidity also depends on the temperature inside the cabinet or grow room.
Where should I place the humidifier?
It is recommended to place it on the ground or in a low area of the crop, never pointing directly at the plants, to avoid moisture accumulation in the buds or leaves.
