Nothing about the word regular implies old fashioned, unstable or landrace. It only says the seeds were made with a true male and will produce both sexes, and a regular pack from a modern breeder can be a highly worked polyhybrid every bit as refined as the feminized version next to it. Common misreadings of seed shop categories are cleared up on https://breederregularseeds.com (https://breederregularseeds.com), including the assumption that regular automatically means cheaper genetics. Judge the breeder and the line, not the label on the tab.
