Does the job Written by meph \| 12 May 2012
easy to set up, didn't need to look at the instructions just looked at the face of the timer for 30secs, which gave all the info i needed. Never experienced any kind of failure or miss-timing. I would actually recommend it over the digital one, plus its cheaper

Works just fine Written by Will \| 27 Aug 2011
I'm using the Grasslin Mechanical Timer and I've had no problems at all setting this up. The included instructions could be made clearer though. For the price it's great.

24 hour Grasslin Mechanical Timer. Is it normal for this timer to "drift" over time. I seem to be gaining about 2 minutes a week. By the end of a month things switch on/off 6-7 minutes early. Always early never late. FYI, its 4 years old. Doesn't seem to hurt my plant though. Just worried a failure is imminent.

It is normal for these timers to drift by a couple of minutes a week as they get older.

Can the Grasslin timer be used to switch power on for 1 minute intervals every hour. This would be for use with an aeroponics system

The Grasslin timer is divided into 15 minute segments, you would need a power on timer to go down to 1 minute intervals. If you are using an aeroponic system, I would advise having the pump run constantly.

I need more information please on the electronic version of the 24 Hour Grasslin Timers. How many segments in the 24hours and how long each segment??

There are 96 segments on the 24 hour mechanical timer, each of which are 15 minute intervals. The digital timer can be set to 1 minute intervals. If you require more precise control, the IWS Power On timer is adjustable to one second.
