You can also judge the ripeness of the Marijuana by taking a look at the trichomes; or little hairs/crystals on the flowers and surrounding areas of the Marijuana plant. If they are transparent its still too soon, if they are milky white they are ready and if they turn brown they have become over-ripe. It is also advisable to follow the instructions to harvest Marijuana seeds on the packet since most reputable breeders also have a tried and tested flowering time for optimum ripeness, potency and flavour of a Marijuana strain.
If you meant when to harvest seeds from cross-pollinated Marijuana plants, then the seed will fall from the flower by itself once it is mature and ready to germinate into another Marijuana plant. Usually, as a best practice to harvest Marijuana seeds, some growers wait for the whole flowering cycle to end just as if they were harvesting the flower.

There is a large debate surrounding exactly when to harvest buds. There are general guidelines for each cannabis subspecies in regards to the optimal time. Indica strains are usually ready after 8 weeks of flowering, and sativa strains after a 10-week period of flowering. Autoflowering strains often take approximately 10 weeks after the seedling stage. Although these guidelines can be helpful in estimating when harvest time may occur, more attention to detail is required to make sure you are spot on with your timing.
Trichomes are important anatomical parts that offer signs for harvest time, although on a much more micro level. Trichomes are minute mushroom-shaped glands that occupy the flowers and sugar leaves, and produce the valuable resin that contains cannabinoids and terpenes. Trichomes are too small to be properly assessed with the naked eye, therefore magnifying tools are required to get a closer look.
