Just what it says in the title. In my grow cabinet I am using an old air hockey fan. The cfm is approximately 95. The fan is VERY loud and I NEED this grow to be ultra stealth, the fan gives it away. I was thinking of just using one of those AC fan speed controller you can find on ebay and amazon for $20 (Amazon.com: Variable Fan Speed Controller). The problem is that where I live the cheapest one I can find is $75!!! It's crazy expensive for something that seems so simple.
SO my main question: is there a way I can SAFELY make a fan speed controller that is cheaper and with out the risk of a fire? Or should I just spend $75 on one?
I can't just by a cheap one from America or china as they use different wall plugs to what we have here in New Zealand. It also costs $40 to ship a $40 controller from Australia so $80..
