I have used Dramm Fogg-it hose nozzles for a variety of watering and irrigation purposes for more than ten years. They deliver a fine mist of water and are available in different strengths, measured as gallons per minute: ½ GPM, 1 GPM, 2 GPM and 4 GPM. I’ve used all but the 4 GPM model. The ½ GPM nozzle, attached to a wand, is perfect for laying down a fine mist of water on a hot deck to cool things down using a minimal amount of water. You can also water very fragile seedlings, or mist cuttings with it. I use the 1 GPM nozzle for watering seedlings and seed beds. The 2 GPM nozzle is great for general watering of established plants. The fine mist will not break down soil structure, and delivers slowly enough for the soil to take in the moisture without run-off.
I like the fact that I can tweak the flow rate by switching nozzles. If one takes too long, I use a nozzle with a higher flow rate. Or if the spray is damaging tender seedlings, then I use a more gentle nozzle. The fine spray is also a great way to revive a heat-wilted plant.
These nozzles are solid brass, tough and well made. I toss them around mercilessly. Also, mine have never clogged. They fit onto a standard ¾-inch fitting, so you can screw them onto your hose, or any water wand with a hose fitting. Their only drawback is that they’re small enough to get lost easily.
