The .5 gallon per minute Fogg-it water fog nozzles deliver a super soft mist that's ideal for greenhouse use, spraying delicate flowers, newly planted lawns or seed beds. This is not a fire hose method of watering. It IS brass though. It should last for years. It sprays water .5 gallon per minute. It mists. We have had bakers, concrete workers and nurserymen buying them.
