I tried searching ebay, with no luck.
There was some 220V timers, but 30minute cycle.
I ordered a cheap 120V timer, cause i already put the seeds in paper towel and soon i will need that timer.
Maybe there is a way to change the current on the timer to 220V?
A regular electrician should know how?

If i will have no choice for the first week or two, until ill get the timer, should i just run the aero cloner for 24/7?
Or perhaps 15 on 15 off with a regular timer?

To my knowledge there is no 240v recycle timer. Why would you need a 240v? Most only use them for pumps and all of the pumps we use are 120v. If you really need to you use the timer plugged into120v to trigger a relay that supplies the 240v, I did something similar and its pretty easy to make.

Have an electrician friend build a relay for you. Amazon sells a 240v contactor with a 120v coil for about $10.00. I made one as a cheap 4 light controller. Lights run on 240v controlled by a regular 120v timer. Relay doesn't care what timer you put on it. However, I still don't see the need for a 240v short cycle timer?

1) why 220v instead of 110v to run everything----if u think running 220 instead of 110 cost less----then WRONG, WRONG.?

2) need to know what size op you're planning?-----depending on your situation, there are several options. One being using a sub panel to go from 220 down to 110 that just about all your ancillary equipment runs on.

3) BTW-----I am an electrical engineer turned weed grower.

Seems to me op has a 230 volt pump so yes use a 115 volt contactor to power pump and timer to control contactor. All of my lights are controlled using contactors. Also comercial time clocks are either 115 or 230 but 15 min intervals unless you can find a digital defrost timer that works with 230v (look in hvac).

Alaric - the current being used in my country is 240V. But i ordered one from ebay. It come without a socket so ill just have to connect one.

Yea i think so..
The power supply of my pc is..
And all the other electrical things i think.
I think 230 allso could work.
For a 120V i need to use a converter (if thats the correct name).
