What's The Difference Between F1, F2, and F3 Weed Strain Seeds?

Just as with common flowers or other household plants (roses, pea plants, etc...), Cannabis seed strains can be grown and crossbred. This is usually done for the purpose of developing new breeds with different characteristics such as the size of the plant, yield, taste, effect, bud to leaf ratio, or other specific traits that the grower desires. As this cross breeding continues, the plants end up forming different weed strain seeds, or generations. These are often described as being either F1, F2, or F3. In order to really make some informed seed purchase decisions it is very helpful to understand the differences between these various seed strains.

F1 Seeds: The First Breeding:

An F1 seed variety is created by breeding together two pure strains. For example, a tall plant (represented with two dominant genes, AA) is bred with a small plant (represented by the two small recessive genes, aa). Since the resulting plants will each receive one gene from each parent, this will result in offspring with the following genetic make-up: Aa. All four offspring will have the same make-up and therefore, will each be tall plants. The difference from the parent generation in this case is that these will not be pure strains due to the presence of the recessive (short) gene.

F2 Seeds: The Breeding Continues:

To create what is known as an F2 strain, the grower will breed two members of the F1 family together. The 'children' that result from this breeding will have the genetic make-up of: AA, Aa, AA, and aa. This is illustrated in the table below:

This means that the F2 seed strain will have three tall plants and one short plant. So, the main difference between the F1 and F2 varieties is the amount of genetic variation and purity of the seed strain.


F3 Seeds: Reducing Variation:

To continue along this cycle, the F3 generation will be produced by pairing those plants which have the desired characteristics together. As an example, if the grower was looking for short plants they would breed together parents with the make-up of (as listed above) Aa and aa. The result of this combination will be two tall plants, each with a make-up of Aa, and two short plants (both aa). This breeding has actually reduce the variation is on the path to producing a more stable variety. This is also often called stabilizing.

Conclusion

With each successive variation the grower is selectively taking those plants which have the characteristics they are looking for and breeding them together. It is basically a way of manipulating the future stock and developing more stabilized weed strain seeds. It should also be noted that the main difference between F1, F2, and F3 is simply the generation it is, since this process can really be repeated indefinitely (although there will come a time when the seeds produce much different results than expected). This is also a bit of a technical process which may even explain the price difference for various strain seeds.

Where to Buy Recreational Marijuana | Colorado Retail Dispensaries

Colorado Recreational Marijuana Dispensaries As of January 1st, 2014, the sale of recreational marijuana to anyone 21 and above is legal in Colorado.  Now that recreational marijuana is legal in Colorado, a handful of medical marijuana (MMJ) dispensaries now sell recreational pot to Colorado residents that don't have a MMJ license (AKA Red Card).

 Even though it's legal under state law to buy recreational marijuana in Colorado without a MMJ card, a number of cities have voted to ban the sale of recreational marijuana. Below is a list of Colorado cities that have bans on recreational marijuana dispensaries.



Recreational Dispensaries in Colorado If you're coming to Colorado from out of town to experience the legal weed scene you're not alone. Thousands are flocking to the state to buy weed at one of the hundreds of recreational marijuana shops now open for business in the state. The map below should be useful for marijuana tourists traveling to Colorado. It pinpoin…

Jack Herer Strain Review | Marijuana Strain Information

Jack Herer Cannabis Strain ReviewJack Herer strain, named in honor of pro-cannabis and hemp activist, and author of two books including The Emperor Wears No Clothes, which has since been used in several efforts to decriminalize the use of cannabis.

Jack Herer Strain is a sativa dominant hybrid Haze crossed with Red Skunk Strain.  The buds of Jack Herer marijuana are a distinct, light green tone.  The smell is one of a citrus haze coupled with a slight scent of the classic fresh cannabis skunk scent.  The buds themselves are fairly dense, thick nugs, that can easily be broken up with ones hands.  Not only did Jack Herer's dedication to promote pro-marijuana legislation earn him his own signature marijuana strain, but in 2003 he was inducted into the Counter Culture Hall of Fame at the 16th Annual High Times Cannabis Cup in Amsterdam.

The Jack Herer marijuana strain is a unique cross.  It's not difficult to tell that Jack Herer is a Sativa dominant marijuana strain.  However, d…
