When you grow indoors, flowering will begin once you switch your lights to 10-12 hours of darkness. For most cannabis strains, the flowering period will last about 7-9 weeks, although some sativas require even longer for their buds to mature.
Then, what week of flower do plants stretch?
Subsequently, should I remove fan leaves during flowering?
Yes you should – but with the correct technique. A proper thinning will remove 20-40% of the mid to upper foliage every 5-7 days. Removing these fan leaves opens up light and produces better air exchange to the lower canopy.
What week of flowering Do buds smell?
Flowering. As a cannabis plant develops its flowers, the smell will start to get stronger and stronger. After around 2 weeks into their flowering cycle, they have a noticeable aroma which will intensify as buds start to grow.
At the end of the week they will be ready. The trichomes stand more erect and the caps swell with newly produced resin. At the end of the week the flowers reach the peak zone. The odor is intense and the glands, filled with resin, fluoresce.
This method is usually employed with indica strains that are packed tightly together in the grow space. When using this method, plants should be flowered when they reach a height of between 15–30cm.
Week 6-8: Ripening of Buds
Any vegetative growth has completely stopped by this point, and all energy is devoted to the cannabis plant’s final stages of life. The buds will grow largest during this time, which is why it is important not to provide any nutrients that promote vegetative growth.
Autoflowers start flowering automatically around 4-5 weeks since germination.
How much a plant stretches at the beginning of flowering varies a lot; some plants might double in height while others only grow a few centimetres. There are two main variables, however, that can give you at least some idea of whether your plants will stretch during bloom, and how much.
Most strains flower in 8-9 weeks, but some can take even longer, especially some sativas. Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall.
Autoflowering plants will stop focusing on root development. The plants will go through a hormonal growth spurt causing them to stretch. Pre-flowers will appear in abundance very quickly after 4 weeks. Avoid training your plants at this point, especially topping.
