Harvest lockup is a unique and creative farming rewards lockup mechanism created by the PantherSwap dev team. This mechanism can help us limit the frequency of harvest to prevent farming arbitrage bots from constantly harvesting and dump.
For example, the harvest lockup of the PANTHER-BUSD farm is 2 hours. It means that farmers who stake in the PANTHER-BUSD farm can only harvest (claim their rewards from farming) every 2 hours.
You can check the harvest lockup on each farm card.
