What would be the best water pump for putting in a 5 gallon bucket/resevouir.. with tubing attached with 1/4" sprayers. All on a timer. This would be for the times i have to be gone for 4-5 days, not everyday use. Does anyone have experience with this? Ive got the idea sketched out in my head and can put it together, my only issue is what type of pump would be best?
