Re: Hive Marking - Florida
You can just use a sharpie marker if you want to and it will last if you spray it with outdoor clear coat. A guy in our been club makes aluminum stencils with the FLO number and then spray paint. I used the stencil and a sharpie on the hives already in use. A little labor intensive but looks nice. My inspector didn't care hows the number was on as long as it was on. Even pencil.
South Florida, 7 hives, 1 nuc, no treatments, foundation free, slatted racks, bottom entrances, zone 10b
