you would think they would work i mean they are just mist sprayers right [SEP] i ordered these to mist my germinating sunflower seeds to keep the soil moist keep in mind they come in a pack of three and i have only used one so far maybe that is why they come in a pack of three because the one i am using now gets stuck what i mean is the sprayer head that you press down on to get the mist to come out gets stuck it sticks down when i press it it worked fine for the first or so sprays but then it started getting stuck very aggravating i tried moving the head around and i even took the head off and put it back on but it still gets stuck oh well you get what you pay for i guess
