The Monkey air circulation fans from Secret Jardin come in three different versions each featuring a unique attachment that allows it to clip to the vertical poles of grow tents with zero chance of it falling off.

Moving the fan up and down is easy, the only limitation is that if you want to hang it off one of the top horizontal poles of the tent the unique no-fall aspect kind of goes out the window...

The Monkey Fans are neat little fans that do the job they were designed to do, they wont fall off and toast your plants and they all offer decent air movement capability for their size.

The 16W model has 152mm diameter blades (195mm total diameter), 2 speed settings and operates in a fixed position.

The 20W model a 170mm diameter blades (210mm total diameter), 2 speed settings and operates in either a fixed position or can oscillate.

The 30W model a 178mm diameter blades (230mm total diameter), 2 speed settings and operates in either a fixed position.

All three can be used on 16mm - 21mm grow tent poles.
