Why Choose Fast Flowering Seeds?

Need your marijuana fast? Fast growing marijuana seeds are the fastest way to go from seed to harvest. These seeds are the result of crossing various cannabis strains with those with fast genetics. We not only guarantee their germination, but we also guarantee they will take less time to flower or bud.

Short flowering time seeds are perfect for any grower with limited time. For outdoor growers in less than ideal climates, it can be difficult to grow many strains. Once the last frost has passed, there is barely enough time for traditional marijuana plants to reach maturity. With a fast flowering time variety, on the other hand, there’s just enough time to produce before daylight hours fade away. 

These fast-grow marijuana seeds are genetically coded to bloom faster. Quick flowering varieties either have naturally fast genetics or are specifically designed autoflowers. The autoflowering method helps produce short flowering THC seeds by making strains that essentially skip the vegetative stage of its life cycle. Instead of blossoming into massive THC strains, these varieties automatically enter their flowering stage, producing a quality harvest in less than 60 days. 

Besides convenience, here are three benefits of quick flowering feminized seeds.

Less Worry About Bud Rot

Bud rot is the bane of weed growers everywhere. Bud rot happens when mold attacks the very buds you want to harvest. The longer your plants are flowering, the more time they have to rot. Mold is dangerous to consume, and any bud with bud rot has to be thrown out – affecting your harvest. Fast flowering marijuana seeds can save you the trouble. 

Mold - resistant seeds are less likely to develop bud rot, and more likely to produce potent THC-rich marijuana.

Lower Costs

Marijuana that takes longer to harvest requires a lot more light. Electricity is almost always the biggest expense for indoor weed grows. If you have cheap marijuana seeds with great genetics, you’re already saving money. If they grow fast, you're also using less light. This means you're saving hundreds in just a few harvests.

Autoflowering seeds need less light, even if they must be fully grown indoors.

More Harvests 

Fast – flowering strains are also ideal for completing multiple harvests – maximizing your overall yield. In areas that support longer outdoor growing seasons, their quick flowering time could mean multiple harvests instead of one. Indoors, fast-flowering seeds can add an additional harvest (or two!) to a growing year. 

The faster your seeds grow, the quicker you can plant your next group of cannabis seeds.

Quick Flowering Marijuana Strains That You Can Grow

Fast flowering THC seeds come in a wide variety of strains. Although their flowering time is shorter, these feminized strains of cannabis still produce a harvest that is rich in THC. This is due to their strong genetics. Many fast-flowering seeds come from already high producing strains. These cannabis seeds can grow quickly without sacrificing THC levels.

To create these seeds, breeders use a variety of methods. In some cases, they merge high-grade clones with 3rd generation autoflowering marijuana. Breeders choose clones with high potency, reliable cultivation, and strong disease and environmental resistance. As a result, these new cannabis hybrids are sturdy, flower quickly, and grow easily.

Fast flowering marijuana is available in many strains, but here are some of the fastest.

Growing Cannabis with High THC

Many people worry that quick-flowering seeds will not produce decent amounts of THC. This is not always true because there are many types of cannabis seeds within the quick-growing variety. In general, growing marijuana with high THC depends on three things. First, you should choose seeds that produce high THC marijuana. Second, you should use feminized seeds to prevent male fertilization. Third, you should practice good grow techniques.

THC is a by-product of excellent conditions while cannabis grows, but what happens after it matures matters as well. Knowing when to harvest will dramatically improve your results. If you gather your buds too soon, they won't be that strong. You should also cure your buds for potent, great tasting marijuana. Curing helps to intensify the effects of THC, and improve the overall flavor.

How to Help Your Fast Flowering Cannabis Seeds Grow Faster

Generally, it takes a marijuana crop an entire season to completely flower, about 3-5 months. However, with short flowering THC seeds, you can reach full flowering in as little as eight weeks. Your cannabis plants can be ready for harvesting after just 6-7 weeks of flowering.

If you are using auto-flowers, this process happens naturally. You can't make it go any faster. However, with photoperiod varieties, you can add extra light or nutrients to help them flower faster. Just remember to properly flush the nutrients out of their system before harvesting. Excessive nutrients do not taste good in marijuana.

Fast growing marijuana seeds can help you harvest faster, but the quality of your final weed is all up to how you grow. To learn to grow the fastest marijuana possible, read our grow guides or visit our forum.
