Autoflowering vs Photoperiod seeds (Switch to flowering automatic or photoperiod)

Photoperiodism is a developmental response to the changes of duration in the cycles of light and colored periods .

Photoperiod Cannabis seeds

Photoperiod seeds may produce male or female plants.
Cannabis is an annual plant, its blossoming period is determined by the seasons and when the bicycle ends, the plant dies. cannabis plants stop growing in size and start to flower and produce buds in Autumn when the days grow shorter.
To replicate this process indoors, growers shorten the light period normally from 18 hours light and 6 hours of darkness ( 18/6 ) to 12 hours of lighter and 12 hours of darkness ( 12/12 ). If the plant continues living under an 18 / 6 hours of light regime, it will stay in the vegetative stage and will not start flowering.

The switch to the unfolding stage is “ automatic pistol ”. They are designed to start flowering at a fixed period of time, despite the environmental conditions and light stimuli .
This makes Autoflowering Cannabis a good choice for beginner growers because they don’t have to worry about guessing if the plant is male or female or when to change the photoperiod. They have fixed and shorter life cycles so they will develop faster than photoperiod strains .

TIPS before starting to germinate Marijuana seeds:

  • Store your seeds in a sealed plastic bag in the fridge and take them out when you decide to plant them. This mimics the season change from Winter to Spring when Cannabis plants usually sprout and promote germination.
  • Soak your seeds in a glass of clean water, at room temperature (20°- 25° C) for 12 hours. Keep in a warm place and signal it to prevent accidents (like drinking the water or throwing them out).
  • Soaking your seeds in a glass of water for more than 24 hours will deprive them of oxygen and they are likely to drown and may not sprout. A seed that sinks after 12 hours it’s likely to be viable and good for germination. If it floats, touch it, and it will probably sink. On the other hand, seeds that float after 12 hours are not likely to sprout soon.
  • Get a water sprayer and set reminders to spray your germinating seeds. A dry napkin may also damage a recently sprouted tap root and kill off your plants before starting.
  • It is very important to track germination dates and stage changes during your grow. Do not forget about your germinating seeds! If you leave them for too long in the container and do not plant them, they’ll grow a long taproot but they’ll end up dying without proper growing conditions. Set reminders and schedule your tasks.
