put some newspaper under your male and flower it in a SEPERATE room. you dont want your other 3 plants all seedy. when youve collected some pollen from the male plant(it wont take much or long), simply take the pollen into your flower room, quarantine the female you intend to impregnate, pop in the barry white now, take a qtip or somethin small like that and gently brush the pollen qtip across some pistils. Mark your limb and then seeds will stay on that limb. You wanna make sure your fans are all off, and when done , make sure to keep that plant away from the others for a bit, theres still prolly a bit of pollen on it. after that, youll need to stabilize your strain which simply involves crossing it back on itself. then you pour the champagne and cuddle.
