What are grow fans?

These devices generate a constant air flow within the growing space, preventing stagnant air and promoting gas exchange in the plants. They are an essential complement to any ventilation system for indoor growing.

Why is it important to use fans when growing marijuana?

Proper air circulation provides numerous benefits:

  • Prevents fungal diseases such as powdery mildew or botrytis.
  • Avoid moisture accumulation on leaves and flowers.
  • Strengthens stems and branches, imitating the effect of natural wind.
  • Homogenizes temperature and CO₂ in the growing space.

Without internal ventilation, even a good extractor fan can be insufficient. Air must be constantly moving within the space to ensure a balanced environment.

Who are these products intended for?

All indoor growers, from small 60x60 grow tents to large rooms, need fans. Their use is especially important during hot weather or when plants are very developed and air has difficulty circulating between them.

What types of fans will you find?

  • Clip-on fans: small, easy to install, and perfect for closets.
  • Oscillating floor or wall fans: distribute air evenly in larger spaces.
  • Industrial or box models: for crops with larger volumes or air flow requirements.
  • Speed-controlled fans: allow air intensity to be adapted to the size and phase of the crop.

Which ones are the most recommended?

Among the users' favorites are:

  • Monkey Fan 20W and 30W: clip-on fans specifically for grow cabinets, robust and quiet.
  • Pro-Vent oscillating wall fan: uniform distribution and high reliability.
  • Pure Factory 40cm pedestal fan: ideal for medium-sized rooms, adjustable in height and speed.

Which brands stand out?

Alchimia works with the best brands in the sector, such as Monkey Fan, The Pure Factory, Cyclone, or Garden HighPro, which offer silent, durable fans specifically designed for marijuana cultivation.

 

Frequently Asked Questions about fans for growing cannabis

How many fans do I need in a grow tent?

It depends on the size of the cabinet and the density of plants, but as a general rule, one or two well-placed clip-on fans are sufficient for small to medium-sized cabinets.

Where are the fans placed?

At an intermediate height, not pointing directly at the plants, to avoid wind stress. Ideally, it's best to move air between and above the plant canopy.
