This microgreen spray bottle is smaller than those that are common in the big box stores. The smaller size makes it easier to handle. The spray bottle is used to wet your soil media and freshly sown seeds. The spray nozzle can be adjusted to the spread you want in case you need to wet the seed surface of it dries out.
There is a filter at the bottom of the intake that will greatly reduce the chance of clogging the nozzle. This is a very handy feature as spray bottles are hard to un-clog.
