They get 4-5 minutes at a clip, 8 times a day. Been running yucca through them too. Timer only has 8 runs in it in a day and that's what I need for some runoff. So I can't really add any more smaller fertigations without adding another timer and there no shot I won't screw that upThe only suggestion I can make and it's going to sound stupid but it's the only thing I found that worked with the solo's is just water as slow as possible.. I have to reduce the drip emitters as low as I can and only fertigate for a couple a mins before they're overflowing
