Fast Growing Seeds

Selected short flowering plants for fast growing!


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 quick harvest and flowering time. 

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 time marijuana seeds can save you the trouble. 

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, you’re not only getting your harvest in less time and with less light. You’re also saving hundreds in just a few harvests.

More Harvests 

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

Quick Flowering Marijuana Strains That You Can Grow

Fast flowering THC seeds come in a wide variety of strains. Although they spend less time cultivating, these feminized strains of cannabis still produce a harvest that is rich in THC when you're growing cannabis. This is due to their strong genetics. Many fast-flowering seeds are created from already high producing strains, minimizing the impact of their quick growth.  In some cases, high-grade clones are merged with 3rd generation autoflowering marijuana to produce first generation cannabis hybrids.

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