Here is a couple of FAQ we get from growers:

Q. Why does one strain cost less from one seed breeder than it does from another?

A.You normally pay for the strain genetics, but this is not always the case, some seed makers (breeders) will always try to charge more on a strain, simply because they seek a larger profit margin than some of their competitors. Also, some breeders have to pay premiums to the original, big name strain breeders, to be able to use the original copyrighted genetics strain name(s).
It's also worth noting that just because you have grade A genetics, it does not always mean your going to get top grade plants. Growing conditions and experience can play a much bigger role in a plants end result than the strain genetics. F.2 hybrids are perfectly ok, and in many cases give the grower more variation of genetics for less money. When breeding marijuana, F.2 and even F.3 hybrids are frequently created in order to discover the full potential of the genetic mix

Q. How old does a plant have to be before it can be flowered?

A.In normal circumstances out-side in the elements a plant may be 3 or 4 months old before it flowers, however under artificial conditions in an indoor situation this process made can be much faster. A seedling grown in good conditions under HPS lamps can be forced to flower, (or may do it voluntarily) at between 5-6 weeks, even earlier for some varieties. Basically if a seedling is big enough to be cloned, (has 5 or 6 sets of leaves and has branches) it should be old enough to show sex, and can be switched to 12 hour light/ 12 hour dark to induce flowering.


Q. How should I store my seeds?

A.If seeds are to be stored for a long time, (it is possible to still germinate seed after 10 years or more!) they should be stored, vacuum-sealed with a desiccant in a cool dark place. For short term storage, (up to 2 or 3 years) in a sealed plastic bag or container in a cool dark place is ok. Adding a desiccant or a few grains of rice helps to absorb any moisture. Using a fridge is ok prior to planting but long-term it's not so good as a fridge has a lot of moisture that is constantly condensing which can harm the seed.


Q. What strains should I buy to grow outdoors where I live?

A.Cannabis is a hardy plant that will grow almost anywhere. However some varieties do better than others depending on the climate, soil structure, and most importantly day-light hours. Here is a chart to help you decide which Kiwiseed is best for your outdoor situation.









Q. What is F2 stock?

A.You start of with homozygous strains. These are considered true breeding strains, and will show little variation in phenotype. When you start mixing true breeding strains you end up with heterozygous strains. The phenotypes in these will vary a little more than the homozygous parents. A heterozygous strain is considered to be a hybrid. An F1, F2, F3 etc are all hybrids.
F1 hybrid - is the first generation of a cross between any two unrelated seed lines in the creation of a hybrid. F1 hybrids can be uniform or variable depending on the parent stock used.
F2 hybrid - is the offspring of a cross between two F1 plants.
A seed bank will have a description of a strain and its characteristics. For F1 seed stock, most of the plants will remain true to that description, with little variance. F2 stock will vary more, your get maybe 3-4 plants out of 10 seeds that will be true to the seed bank description. The rest will be a little different in their phenotype, producing different flowering times, different yields and different tastes and smells. Without this kind of experimenting, new combinations of genetics (and therefore new variations of marijuana) would never be found.

Q. What is phenotype?

A.A phenotype is a particular trait or characteristic of a plant. It could be high yield, short growing mature or fruity aroma. A seed bank will normally give you a description of a strain, listing the best phenotype. F2 stock phenotypes will vary more than F1 stock, and as you progress to F3, F4 etc, the variation becomes greater.
So basically, when you order an F2 stock of seed, be prepared for some variation in the plants phenotype. However no potency or yield is lost between F1 and F2 plants.
When ordering F2 stock, the idea is to search out the better phenotypes, and clone them so in future you only work with the best genetics of the bunch. With F1 stock, you should have more uniform plants that all perform similar, and if the breeders done his job correctly, this should be as close to the original description that tempted you to buy the seeds in the first place as you can get!

Hi MG, sorry to nitpick a well written and useful thread but I found these sentence's a little Misleading;

A phenotype is a particular trait or characteristic of a plant. It could be high yield, short growing mature or fruity aroma.

Very few strains are Homyzygous even for a few trait's at a time...even if they are 'True-breeding' strain's. That is a myth and a misuse of the term Homyzygous!

A phenotype is a mixture of one or varous Trait's and characteristic's shown in one or many plant's from the same cross that distiguish it from the other Pheno's.....Not necessarily a single trait of a plant! That is a little misleading for a noobie.

A phenotype is a characteristic of a plant (height, smell, yeild, etc.). One plant can contain many phenotypes. The word phenotype is often misused. Chimera and midnight both explain it the same way.
