Grow fans

Depends what type of fan you require, I recommend one that exceeds 250cfm and an EC motor and speed controller and inline type,runs quieter. They do sell to Europe direct, but units cost is massively higher on shipping. Obviously I use AC cloudine. Read reviews before you buy. Many have cheap bearings or are noisy Chinese copies. Don't go for the old school high cfm extractors unless you like a sound like a cold war era soviet bomber ready for take off. Hard question not knowing requirements and extraction set up with filters,bends etc, but go bigger and dial it down.

Currently using a Garden Highpro 20w. Moves a ton of air but a little bit noisy, but not too bad when the tent is closed. Growing in Malta, EU
