This chart is a guide for 8 week flower maturing plants.
Once you start your flowering hours the marijuana plant will change from vegetative to flowering within 3 to 4 days. Most modern hybrid plants take seven to nine weeks to ripen once flowering is initiated.
Week 1: Growth slows in the plant.
Week 2: Flowers will start to appear at the nodes.
Week 3: The plant will continue to grow vegetatively as the plant will grow between 20-50% larger then when flowering first started.
Week 4: The plant will end all vegetative growth and focus energy on flower growth. The smell of the plant will change as it starts to produce trichomes.
Week 5: Flower growth comes quickly as the flowers become thicker and appear in new places. The odor again increases as more trichomes are produced.
Week 6: Flower growth continues for eight week maturing plants and flower growth slows and stops in seven week maturing plants. Swelling calyx’s can be more noticable. The plants odor intensifies in the seven week maturing plants.
Week 7: At the end of this week, the seven week maturing plants will have very swollen calyx’s as they fill with THC. The trichomes stand up and the caps swell with new resin. It is at this point the plant is ready for harvesting. In the eight week plants the flower growth stops as they start to mature.
Week 8: In the eight week varieties the flowers are fully ripened by the end of week. The peak harvesting period is in the last 72 hours. Once the trichomes stand up and have plump caps its has reached the peak and anything after will only deteriorate the potency of the flower.
In some varieties of 8 week flowering plants it may take an extra week to reach the peak harvesting period. It is always wise to monitor the trichomes resination with a hand held microscope or lens once you reach the end of week 6. Via (only registered users can se the link, login or register)
