Having a vast cannabis market, it’s very difficult to pick the right strain. Don’t worry!

I have gathered a list of fast growing marijuana strains here just for you. So let’s get started!

Cannabis Strains With Short Flowering Period

For the short life and growing period, autoflower cannabis strains have been favorites among many weed lovers for the last decade.

Unlike conventional photoperiod strains, autoflowering plants start to bloom not when you change the light cycle to 12 hours of dark or more but when plants attain a particular stage of maturity. It usually happens between weeks 2 and 5.

Let’s get started with the fastest growing weed strains!

Critical Kush

Critical KushFlowering in just eight weeks, Critical Kush is on the top of this list.

When you grow this fast growing Indica, make sure you have plenty of space in your backyard. As it completes the flowering stage by week 8 to 10, you can expect a quick harvest from Critical Kush.

The leaves of this strain showcase a bright shade of green and are twisted through with orange pistils. The shining trichomes cover the flowers in and out, giving them a beautiful look.

Since the buds are thick and large, it is almost impossible to break them with bare hands.

Critical Kush has a balanced ratio of THC and CBD components. This quality makes it a perfect strain for night owls to relax.

It also helps people with muscle spasms and depression to reducing pain and stress.

How Growing Fast Flowering Cannabis Helps

Grows quickly: You can harvest fast flowering strains between 1-5 weeks, quicker than regular strains. It helps you if you want multiple harvests.

Surviving in any climate: Fast-flowering weed seeds can be planted in cold weather conditions and bloom in warm temperatures.

Resistant to bugs and diseases: Because of their short flowering time, novice cultivators can bypass the bugs and mold issues.

Low risk: Since quick flowering strains require a single light schedule, there are significantly fewer chances of any safety hazards.

Issues You Face While Cultivating Fast Flowering Strain

Fewer yields: If you choose to grow fast growing weed seeds, you’ll have to satisfy yourself with smaller yields.

Fewer cannabinoids: Since the fast flowering strains grow rapidly, they tend to have a lower cannabinoid ratio than photoperiod strains.

Beyond this, you won’t find any significant drawbacks of growing strains with a short flowering period.

Things to Take Care While Growing Quick Flowering Strain

Besides choosing a specific strain that is popular for its quick flowering period, there are some factors you need to consider to speed up the process.

Pick the right strain – Indica vs Sativa vs Hybrid

Indica strains are the most picked strains when it comes to short flowering strains. Moreover, they also offer a higher yield than other competitors.

On the other hand, Sativa strains take a longer time to bloom, having a smaller harvest. In comparison, hybrid strains carry the best qualities of both Indica and Sativa. The flowering phase and effects depend on the gene of a particular strain.

Resolve the issues ASAP (as soon as possible!)

Many beginner growers lose crops as they don’t pay much attention to the growth of the plants. The growth continues to drop if you don’t pay much attention to it.

Mold, pests, nutrient burn, and heat stress are the major problems you should take care of while growing fast flowering weed seeds.

Lightning schedule

Lighting is an essential part of indoor cannabis growing. You should provide 24 hours of light schedule when your plants are in the vegetative phase. As a result, your plants soak more energy to flourish well.

Then, induce the flowering stage by providing 12 hours of light schedule daily.

Trial and error with growing methods

If you’re starting with cannabis growing, try cultivating weed plants indoors, as you’ll have more control over the lighting and temperature.

By doing this, you can start the flowering stage sooner than outdoor growing.

Moreover, choosing the right growing method also matters. Go for hydroponics instead of soil for rapid growth during the vegetative period.

Final Thoughts

For impatient growers like me, there is nothing as attractive as finding fast flowering weed strains.

Don’t confuse fast flowering with high-quality, so make sure you do proper research before putting some real money into these magical strains.

The above-mentioned fast flowering cannabis strains are most trusted by expert growers and help you choose the one that suits your requirements.
