1st time using a ediy cloner..couple questions

I made a cloner looks identical to a ez cloner

where do i find the timers to run it 1 min on 4 off?

im going to do the cuttings dip them in clonex cutting gel then put them in the plugs.

for the water im using RO water

im adding 200ppm nutes of house and garden aqua flakes a&b

im also adding great white premium mycorrhizae into the cloner

anyone see any issues here?

also if i cannot find the timer like that what about using a 15 on 15 off timer?

I have a EZ-Clone 60.All I used was spring water that I bought from the store and I bought some Olivia's Cloning Solution from Worm's Way.All I did was follow the directions on the bottle of cloning solution and turn the machine on.I had about a 99% sucess rate.I did about 300 cutting and all of them took root,except for 2 of them.The EZ-Cloner runs non-stop,it does not let the roots dry out.It does not have a timer.The EZ-Cloner has a water pump and a air pump.I am not a expert by any means, but I do not think you need all of those nutes you were talking about.From what I have read to much nutes is not good for trying to get clones started.
