1/4-in. Barb 1-GPH Drip Irrigation Flag Dripper/Emitters | 10-pack | 65199

These little flags screwed onto my stakes in a few minutes and the flow is steady enough that I can stop worrying about my hydrangeas drying out. The 1-GPH rate seems just right for a slow, deep soak without any runoff.

Exactly 1 GPH on all ten, so my raised beds are finally getting even water without any runoff. The male threads locked onto my 6-inch stakes with zero leaks, and the flag makes it stupid easy to see which line is which.

The 1/4-inch threads fit my stakes without any wobble, and the 1-GPH flow is perfect for my young shrubs. Only ding is the flags are a bit stiff to rotate one-handed, but they hold their position once set.
