At City Seeds Bank we receive a lot of questions about the different seeds that we offer. So let’s take a look at the different seeds that are available on the market.

Seeds can be put into 3 categories:

  • Regular seeds
  • Feminized seeds
  • Autoflowering (automatic in short) seeds

At City Seeds Bank we do not offer regular cannabis seeds but to explain to you how seeds work, we need to start at the basics, which are regular seeds.

Regular Seeds

Normally, cannabis seeds come from a male and female parent and their seeds are able to produce male and female plants as well. The difference between male and female plants is that only female plants produce buds, meaning that only female plants can be used for the production of weed. When still in the seed stage, it is impossible to tell if the plant will become male of female; the sex can only be told when the plant enters the flowering stage.

Depending on the amount of time and space, purpose, personal preference and level of expertise you can decide which seeds (regular or feminized) suit you better. When you are growing to produce new seeds, you will need both male and female plants. But when producing weed is the main purpose of growing, the male plants need to be removed to avoid pollination because this will only lead to little or no production of weed.

So what are the pros and cons of regular seeds?

Pros:

  • Regular seeds are probably always cheaper than the same strain in feminized seeds.
  • You will be able to produce your own seeds

 Cons:

  • When growing for cannabis, male plants need to be removed when entering the flowering stage.
  • Harvest might be limited because there is no control over the sex of the plants; all males need to be removed.
  • Plants need a certain ratio of light/darkness during flowering.
  • When you have limited space available, this might not be the best choice; you will always have less plants to harvest than initially planted.

Feminized Seeds

Feminized seeds are bred to ensure that every plant is going to be female; meaning that there will be no need to identify the male plants for removal. If you want to cultivate fast without too much hassle, this is the way to go. Regular feminized seeds need 18 hours of light a day in they grow period and will start blooming when they at least get 12 hours of darkness. This is a process that will naturally occur as the days get shorter by the end of summer. For this reason, your harvest will not be ready before September.

One issue with cannabis plants is that, under certain circumstances, they will go into survival modus and become hermaphrodites. With good quality feminized seeds chances that this will happen are slim to none.

So what are the pros and cons of feminized seeds?

Pros:

  • Feminized seeds produce 100% female plants; this makes the use of these seeds very cost-effective.

Cons:

  • More expensive than regular seeds.
  • Total grow time
  • Reproduction will not be possible because there won’t be any male plants.

Autoflowering Seeds

Please note that all the seeds in this category at City Seeds Bank are feminized. Regular cannabis strains recognize the change in seasons and the decrease in daylight hours; a sign for the plant to start flowering. Autoflowering (or automatic) strains have the advantage that at a certain point in the grow cycle they will start flowering, regardless of the ratio light/darkness. These autoflowering seeds are developed by cross breeding Indica’s and Sativa’s with Ruderalis. Ruderalis is a cannabis strain that contains low levels of THC but is not dependent on the amount of light/dark it has been exposed to, to go into the flowering stage.

Outdoors, automatic seeds grow and bloom faster than regular feminized seeds.

In general, automatic strains are small which makes them ideal for outdoor growth. However, the yield is about 50-500 grams per square meter, depending on how well the plants are taken care of.

What needs to be considered is that plants from autoflowering seeds cannot be cloned. As opposed to regular feminized seeds, you would have to buy new seeds every time.

Another important difference lies within the THC and CBD-levels of the plants. Automatic strains produce less THC than regular feminized seeds, this results in a high that doesn’t last as long as when smoking weed from regular feminized seeds.

So what are the pros and cons of automatic seeds?

Pros:

  • Short growth and flowering time, harvest can take place within 10 weeks max.
  • Most automatic seeds are resistant to molds and diseases because they all have genetics from the Cannabis Ruderalis.
  • There is no need to change the light schedule with these seeds.
  • Automatic strains do well outside, also in short summers with little sun.
  • The plants won’t grow too tall, which is ideal for discrete growth.

Cons:

  • Because of the short growing time, the harvest is usually smaller.
  • Plants cannot be cloned.
  • Initiation of the flower period cannot be influenced.
