2 Days in a row HPS light failed to start. Starts after cycling power

At this point, apart from getting in spare kit so no failure can slow you down, I would get either a relay or contactor box and a new timer (digital, I have also yet to find a reliable mechanical one) and have the new timer run the contactor box or relay.

This is definitely what I am going to do. I don’t have the time to build one so I will purchase something.

Another concern, by switching back and forth between MH and HPS, you may increase the chance of unwanted sex organs.

I only put an MH in for 1 day when the problem started. I have been using the HPS exclusively since then. Hopefully the girls won’t get mad…
