How to Grow Auto Flowering Cannabis Seeds

If you haven’t heard about how to grow auto flowering cannabis, the term refers to those plants which do not require a specifically timed light cycle, and will instead flower all by themselves, following a period of approximately three weeks in a vegetative state.

The auto-flowering plants are derived from cross-breeding with cannabis ruderalis, which is sub-species of cannabis renowned for its ability to auto-flower, as well as its relatively short stature. By crossing ruderalis with indica or sativa strains, you can create a plant which grows and flowers all on its own, irrespective of photoperiods.

Why grow auto-flowering plants?

The real advantage of growing auto-flowering plants is that they are not subject to any lighting requirements, and will produce buds regardless of how much sunlight they receive.

If plants get more than 12 hours of sunlight each day, it won’t be a problem, and they will still produce bigger buds than most other cannabis plants. In addition, if you have a discreet growing operation, these plants are much smaller than normal cannabis plants, and will attract far less attention from curious neighbors.

How to grow auto-flowers

These plants typically grow very quickly, so more preparation is needed upfront to be ready for that rapid maturity. While the plants are in vegetative phase, which could be as short as two weeks, you’ll need to train the plants by topping each plant after it develops at least three nodes. Alternatively, you can simply pull the plants down in a sideways direction to force new upward growth. Once plants begin to flower, no further topping should be done, and pruning should be discontinued after one week.

Ideally these plants should be grown in a greenhouse, because the best time to start them is either in March or September. At this time of year, it could still be chilly and rainy, and plants will need warmth without excess rain. Greenhouse growing will eliminate both of these potential hazards, and provide the most favorable conditions for flourishing.

Less feeding is required by auto-flowering plants, because they do not spend long in the vegetative state, and because they will mature into smaller plants anyway. This means feedings should be light, even with typically necessary components like nitrogen. Since they grow quickly, the overarching canopy is always less pronounced, and buds appear further down on the plant.

Establish a continuous growing process

This means that you should harvest in a sequential manner, taking the colas first, while allowing a little more time for the buds to develop and get denser. While you are in the harvesting process, it’s a good idea to pop the seeds from your plants, so you can begin preparing for your next crop. You can even plant these seeds immediately and in the same greenhouse room as your mature plants, since lighting requirements are not an issue for either group.

To get your initial batch of seeds, you can search online for seed banks, but make sure to pay close attention to the legal requirements for ordering, to make sure you don’t run afoul of local or interstate authorities.
