What Are Fast Growing Weed Seeds?

Many people confuse fast growing cannabis seeds with autoflowering strains. While autoflowering strains can be part of the equation for breeding purposes, these plants are much different. 

Fast cannabis seeds are usually bred between photoperiod weed and autoflower strains. The end result is a plant that can produce flowers very quickly but is still reliant on the photoperiod for transition signaling.

Just like regular photoperiod cannabis, a 12/12 light cycle will trigger your fast version seeds into the flowering cycle where they usually mature within 8 weeks. 

Check Out the Differences Between the Main Types of Cannabis Seeds

There are many differences between each of the seed types, with advantages for each. Check out the main types of cannabis seeds and how long they will take to finish, both indoors and outdoors. 

Seed Type Difficulty Feminized Photoperiod Flowering Time Yield Size 
Fast Version Easy Yes Yes 7 Weeks Medium
Feminized Advanced Yes Yes 8-10 Weeks High
Regular Medium No Yes 8-10 Weeks Medium
Autoflower Easy Can Be No 6-8 Weeks Low

Why Choose Cannabis Fast Version Seeds?

The most common reason people get fast flowering cannabis seeds is that they want to harvest their plants faster than they would with traditional weed. You’d be surprised at the additional benefits this fast version will get you, including: 

Saves you from the dreaded bud rot. If your climate is too moist or your flowers haven’t dried out properly then mold can form inside the bud and start to rot it from the inside out. Fast version seeds grow quickly so any mold doesn’t have time to form while you’re growing your plant. 

Costs are lower. Since these fast version seeds flower much sooner than traditional forms of cannabis, you will end up using a lot less electricity with your lights, heating/cooling, and timers. 

Good potency and harvests in less time. Just because your plants finish flowering faster doesn’t mean that they lack THC potency. These buds will still turn out massive and strong, they just don’t have as many of them.  

They can be grown in small spaces. When growing fast flowering weed seeds, you can expect short plants, which is ideal for small grow spaces. Since they sprout limited flower sites you can always implement some LST (low-stress training) techniques such as SoG (Sea of Green) to increase the potential yield for your plants.  

Can thrive in unstable weather conditions. Severe heat or excessive rain can put a halt on cannabis plant production. Fast flower seeds grow quickly so they are less susceptible to the withering effects that advice climates can have. Additionally, they are also resistant to pests such as insects looking to take a bite out of your plant.  

Great for beginner growers. Novice growers will already have so much on their plate, managing a cannabis plant from seed to harvest. Fast growing cannabis seeds simplify the process by producing hardy plants that are finished quicker than most problems can take to turn south.  It also enables the grower to get comfortable with the fast version seeds before moving on to other types.

How to Germinate Fast Version Cannabis Seeds

Germinating your fast cannabis seeds is the same process as for regular seeds. If you’re new to weed growing, here are the tools that you’ll need to germinate fast growing marijuana seeds:

  • Paper towels
  • Tweezers
  • A bowl of water
  • Two plates
  • Fast growing weed seeds   

There are multiple ways to germinate your seeds but this method is the simplest and most efficient way to germinate multiple seeds at once. The steps are simple, and as long as you follow this guide, you should have no issue germinating your seeds. 


  1. Moisten the paper towels, not too wet that they’re soggy but wet enough that the water can permeate the seed shell.
  2. Put one of the paper towels on the plate and set the seeds onto the towel using the tweezers
  3. Cover your fast cannabis seeds with the other sheet of damp paper towel. Add a little more water to ensure enough has penetrated the towel. Try not to form any puddles. Check for any excess water underneath the seeds. 
  4. Your fast growing cannabis seeds will need a dark and warm place to coax the small taproot out of it.
  5. You should see the small white taproot within 1-4 days and that is your signal to transplant it into a new pot.  

Is It Easy To Grow Fast Version Seeds?

Growing fast version seeds has never been so easy. A combination of stable genetics and durable strains makes it easy to grow both inside and out. 

The first thing you need to do is figure out where you want to grow your fast marijuana strain. These cannabis seeds can grow in smaller spaces since they are quick to flower which makes them ideal for growing in tents or small plant rooms. 

Luckily, the growing guidelines are the same for regular, feminized, or fast flowering seeds so you won’t need to learn any additional tricks. Provide your plants with proper lighting, ample nutrition, and plenty of water, and you’ll be rewarded with plenty of dense buds. 

Light Cycles

You’ll want to stick with a 16/8 photoperiod for your vegetating strains, this means 16 hours of daylight and 8 hours of darkness. Once you want to change it over to flowering, just switch up the light cycle and do an even 12/12 photoperiod. 


Various nutrients are required throughout the life of your weed plants. In the vegetative stage, it is wise to provide apple nitrogen and phosphorus so your weed develops a strong root and leaf foundation. As it transitions into flowering, providing enough potassium ensures strong flower production.    

Temperature and Humidity 

The easiest way is to think about the different conditions that your cannabis plant will experience outdoors and apply them to your indoor grow. The temperature of your environment should always stay within the range of 65-75 degrees Fahrenheit. Using high humidity and warm air will get your seedlings to wake up without any stress. 

Here are some guidelines for optimal humidity settings in the various stages:

Seedling: 65-75% relative humidity

Vegetative: 50-70% relative humidity

Flowering: 40-50% relative humidity

The idea is that earlier in the weed plant life you want higher humidity and temperature and as the flowering stage comes to a close you want less humidity to avoid bud rot.

Facts About Fast Version Marijuana Plants

These fast strains are a fascinating scientific marvel created by talented breeders. They hold so much potential with proper seed production. Here are some facts about this unique type of cannabis that you can grow at home. 

Fast version seeds have Ruderalis genes. They contain the same genetics that enable autoflowering strains to flower without a light cycle; However, they still retain their photoperiod qualities seen in regular and feminized seeds.  

Fast strains can flower in a very short time. Some of the quickest fast version seeds can start to flower within 6 weeks of germination. This is on par with autoflowers as they can start in as little as 5 weeks. They still require a photoperiod change, which is 12/12.

Fast growing cannabis seeds are generally feminized. Due to specialized breeding techniques, creating stable genetics also means that these fast version seeds will almost always sprout as a female, providing beautiful buds without the possibility of seeds in your crop.
