The way I do it is keep all my males together and isolated, and keep all my females together far away.
When it is time to pollenate, I take a paint brush and a small envelope, and carefully harvest pollen from the chosen male. I then seal the paint brush inside the envelope and tke my selected female away from the other ladies and pollenate just a couple very low buds with the paintbrush. That branch gets a label giving the cross. You can do several crosses on the same plant this way. The female is allowed to rest a couple hours before being misted with plain water and then returned to the flower room.
stinkyattic Reviewed by stinkyattic on . How pure can any strain be? This has been rattling around my brain especially after reading the posts to that "Don't kill males thread" . Males spread their pollen far and wide as much as naturally possible. Therefore, seedbanks that grow 20-30 strains cannot physically guarantee any of their strains are "pure", or even really F1s. Unless they have 20-30 totally isolated grow rooms for each strain, the females will get pollinated by any flowering male in the area. At $5+ a seed (cheap ones) that little fact must be kept Rating: 5
