Water seedlings quickly, with no flattened plants! The Dramm Redhead water breaker catalog description is, in my experience, perfectly accurate: “Softest flow of any water breaker that we have tested while still offering enough water volume. Perfect for all watering needs, especially for young seedlings. Stainless steel screen for years of reliable use.” The flow is high volume and incredibly low pressure and gentle. Admittedly, as I often water from a well, the water pressure is quite low to begin with, but I also use it with the pond pump, which puts out 50-60 psi (luxury!), and the Redhead is excellent. And, I’ve had the same head for three or four years banging around in the greenhouse and out in the field with no problems.
From the Dramm site: “The 1000PL Redhead water breaker has over 1,000 micro holes that create an ultra-soft flower shower which will not disturb delicate soil or harm tender plants. Use with a Dramm In-Line Hose Filter to prevent clogging. Made in U.S.A. from ABS plastic and stainless steel.”
I have two, purchased from William Dam Seeds.
