| Every calyx has 2 hairs, thats a flower, a cluster of flowers is a bud,(in the case of cannabis), a cluster of buds is a cola.
It looks as tho those photos are of a blant about 2 weeks into flowering/3 to 4 weeks into 12/12photo period.
From the date of those pics, you've got at least 6 weeks if its an 8 week til bud variety,but cannabis can take alot more than 8 weeks, some times only 5 weeks, but sometimes more than 12.
Most indo varieties are 8 weeks, if thats your plants source it'll probablly take that long, but if you find a plant or find a seed, it's not unlikley that it'll be more like 10 weeks.
When 12/12 is initiated, the plants begin to "bolt" do to an increase in auxin levels, by the same chemical reaction they begin to flower as they are bolting. When this vetical growth stops the flowers will become more plentiful filling out the space they are in, when this flower formation begins to slow and vertical growth is over, stop fertalizing, and after you flush with water, keep water to a minimim.
When vertical growth and flower emergance stops, the plant doesnt need water to grow, only to retain its constitution. Excess H2O will slow time to harvest, and increase chances of molds/rot.
After vetical growth and flower emergence come to pass, the calyx really begin to swell, tho some have already began, they really start to swell in the last couple of weeks(if you have an 8 to 10 week strain).
When I was growing up there was a safe way to eye-ball harvest time.
When 70% of the hairs have turned color, pick 'em.
But if you have a realativly good magnifying glass, or a trained eye, watch the trichomes(crystals) develope, this is the best indicator for harvest time.
If you pay attention to the trichome development you'll watch them turn from tiny hairs to things swollen with oil that looks like a mini-mushroom, when th trichomes are at there plumpest, its time to pluck |
