Auto Flowering vs. Photoperiod

By Castulo Zane


As most weed lovers know, weed reproduces by having male and female plants. The male makes the pollen. The little girls create the seeds.

Weed lovers also understand that photo-period (the length of day or light period) regulates when the two genders generate their respective flowers. Outside, plants start developing buds as the days shorten. Inside, growers manipulate the light period to be 12 hours or less each day, and at least 12 hours of uninterrupted darkness.

Flowering, therefore, is a function of photo-period. In a natural setting outdoors the plants will bloom and mature on the Earth's natural timetable. The days will grow shorter incrementally as the Earth tilts on its axis.

The further north you go the quicker that change occurs. And that means that your plants have to change from the veg state to the bloom state and finish flowering before the cold and wet come. The buds can freeze or get moldy in cold weather.

So what is auto-flowering? It's a simple concept. An autoflowering plant goes into the bud cycle as a result of age, not photoperiod. From seed the plant has to grow through a veg period. However, it can start flowering after 5 weeks. Some autoflower strains can be harvested after only 8 weeks.

The advantages of an auto-flowering strain are clear. They mature faster. They don't need light manipulation. You can have plants in veg and bud at the same time. If you're growing outdoors you can get an early start.

Auto-flowering seeds are said to be better for beginners. The plants are often small. They can be 20 inches high at harvest time. That means that a May 1st planting should deliver buds on July 1. It even means you could grow and harvest two outdoor crops per year.
