I got the growbright 4 inch ..... its kinda lout but works great! I got the scrubber as well and am very happy. From HTG for a good priceJust wondering if any one has had a good experience with any of the cheaper fans like the valueline or the growbright. How loud was it? Did it last or break? Just curious before I spend the money on a Vortex. opinions and comments welcome and wanted. Thanks
Gonna second the active air. Never had another fan, but its working perfectly for my 600wBest bang for your buck is one of these cheaper fans. Don't be fooled, many of these aren't worth a damn but some are great! I've bought 5 of the hydrofarm active air 6" centrifugals, and alongside my vortex it is the same volume and just slightly less rated CFMs, but for half the price!
If you use insulated ducting they are even quieter. This is the cheapest place online to find them that I have seen, but I'm sure any local hydro shops wouldn't have any trouble getting them, albeit for more money probably.
Hydrofarm Active Air Centrifugal Fans (https for security, the fans are green)
Growbright -- 52 decibels (htgsupply)
Thats the only one I could find. Similar speeds will have similar ratings.
My fan is behind two closed doors and I can no longer hear it, if that helps any.
