typically, your plants will be in flower 8-10 weeks (it varies with strains, some Thai sativas go for months ! ) ... ( ignore the color of the hairs, means nothing, go by the color of the trichomes ) read the FAQs posting about 'when to harvest' ... personally, I would let them grow until your seeds are fully mature, why miss an opportunity for a nice bunch of seeds ? ... contrary to urban myth, a seeded plant is NOT less potent than a sinsemilla plant (without seeds), it's a drag to clean, and manicure, but potency is fine ... I am hoping for a male next crop, I'm tired of paying big bucks for seeds ... btw, your plant looks great, you should be proud of your efforts ... :smokin:
