so I don't sell out in 5 months
This is an big indicator of if you are selling you honey under the price you can get for it.
If you run out many months beefore the next harvest you most likely need to see over the price you are selling your honey.
If you don't think your honey should cost more buy a notebook and record everything
you do under a year connected to bees, hives, honey, gas, driving, beekeeping clubs activities, beekeeping courses, hive, box,frame,building bee purchase, new queens and selling the honey.
Don't forget the notebook and pen ;)
After you take all this into account no one will bee able to afford to buy your honey if you charge minimum wage for your efforts.
