are autoflowers worth growing

There are two main phases of the cannabis growing cycle: the vegetative phase and the flowering phase. Another type of cannabis—known as photoperiod cannabis—requires a shift in the light cycle to trigger flowering.

The very name “ruderalis” stems from the Latin word “rudus”, meaning rubble. The subspecies appears in urban settings thriving in broken ground, close to demolished buildings, and in roadside ditches.


Here are a few of the fastest autoflowers around:

The ruderalis subspecies adapted to the cold and often harsh environments of Central Asia, Eastern Europe, and Russia. These regions feature a considerably shorter growing season and colder temperatures.

For this reason, ruderalis abandoned the strategy of waiting for the seasons to change to trigger flowering. Instead, the subspecies developed an autoflower gene to ensure reproduction before the temperature plummets.

A: While there's nothing wrong with auto-flowering strains, it's important to get the strain you want. If you just ordered today, try emailing/calling the seed bank and tell them what happened.

If these seeds are all you've got, it can't hurt to grow them and get a feel for growing.

The cool thing about auto-flowering strains is you just give them 18 hours light and 6 hours dark the whole grow, instead of changing the lights to 12-12 halfway through the life cycle to induce flowering like with regular marijuana plants.

I've order the wrong seeds by accident before, with Nirvana Seeds, and I just asked them to switch. With Nirvana Seeds, it wasn't a problem.

Q: I screwed up and ordered autoflowering seeds, is it a waste of time? This is my first serious grow… and I ordered northern lights autoflower and short rider, which seems like its an autoflower.

Firstly, a little history. For thousands of years, cannabis has been a photoperiod plant. This means that it uses a photoreceptor protein, such as phytochrome or cryptochrome to sense seasonal changes in night length. Once days lengthen to above 12 hours, these chemicals induce the process of flowering. No matter when you plant a cannabis seed outdoors, it will continue to grow until the nights shorten. And of course indoor grow rooms exploit this fact by choosing for how many weeks cannabis is kept in growth and when to flip to flower.

Thanks to the great work done by breeders and the awesome these faults are now resolved.

15 years ago things began to change – and radically.

Something drew me to autoflowers: they were quick to go from seed to harvest, with a vigorous growth unseen in standard cannabis plants. They were easy to grow, and outdoors I could get several cycles of crops in whilst my regular plants were still growing … and growing. Even in the indoor grow room autos were less demanding. They tolerated electric power cuts in stormy winters and flourished even in cheap not so light proof as they should be grow tents.

A small group of enthusiasts experimented with crossing cannabis sativa with its little known Russian cousin, cannabis ruderalis. Having had to adapt to short summers, these plants grew smaller than standard cannabis, and contain low THC levels. More importantly, they begin to flower upon maturity rather than the light cycle.

Spin back time by 15 years and autoflowers got a lot of bad press. The general consensus of most cannabis growers was that autoflowers were a fad, not worth the time, money and effort. The world of weed has changed a lot since then, so we ask “are autoflowers worth growing”.
