Timer help

So in doing a areo bucket with a single sprinkler head attached to a 300l/h pump this part works just fine. The problem im having is I can't program my timer to run 15 mins and off 15mins I can only do this 8 times because my timer runs out of program 8 total. I read somewhere to let the pump run 15mins and off 15mins any help would be wonderful. Oh btw the timer is a hydrofarm tm01715D

You might need a different timer. I use this Timer Outlet, Nearpow Multifunctional 7-Day Cycle Programmable Plug-in Digital Timer Switch for Appliances, Extra large LCD Display, 19 Programmable Settings, Seconds-Interval, 15A/1800W https://www.amazon.com/dp/B0752PHMTL/ref=cm_sw_r_cp_apa_i_BoHECbBKDN8ED

Works like a charm and has for 1 year now never missing a beat. I run 30 seconds on, 5 minutes off. But of course this will differ depending on what kind of spray heads you use.

You can buy one of those cheap timers at Walmart,Target or Home Depot, with the pins that you can push up or down for on/off.



But is it really necessary to run your sprayers 15 on/15 off?
There are so many variables that would work as well. 15 on/45 off, 30 on/120 off, etc.
Don't forget that for example in a bubbler the roots are submerged in water 24/7.
The only thing is that your pump might heat up the water too much if you let it run 24/7.
