rheostat question

Is there a way to put a rheostat (fan speed controller) on some type of timer so that the fan will slow during certain times and then turn back on to full speed during other times automatically? Or maybe someone knows where to get a rheostat with this feature built in.

The easiest way to do it would be two fans. The one on the rheostat would be off when the other on is on. I am sure someone has a switch that could do this. When the timer comes on it would have to shut the circuit to the rheostat off and turn the circuit to the fan on. so I geuss that would be a dpdtoc. I just thougt of something, it would be the same as an override float switch, kinda? VV

? I am an extreme newbie when it comes to electrical jargon. I have no clue what any of that meant. Could you please explain it like I'm a fifth grader. Thank you.

Why not just leave it on? But if you really want it, look for for fans with a thermostat and just let the temp control whether its on or not.

Yea man..you can do that.. I may do this with my cab.. I think this is what you are talking about. I cant take credit some bad mo fo posed this on here before.

I actually thought of a diy solution. Incase anyone is interested you split an extension cord for it so that you plug the female end into the fan and then split to 2 male ends (strange, I know) you then hook the two ends to 2 timers one is just set to the fan and the other is set to go on shortly after the first goes off (not too short to avoid some strain on the fan) the second timer is set to the rheostat and turns the fan back on at a lower rate, later turning off once again before the first timer turns back on. I did the research and even if the first timer malfunctions and does not turn off before the second timer turns on your fan will not blow. I think this method would be good for stealth grows when people want their fans to quiet down during certain hours of operation. I'm not sure how many people would be willing to go through this trouble, but I hope it can help someone.
