We finish the chapter dedicated to the G13 after having revealed its “mysteries” and ending with the myth of its origin, although as with most of these “historical” varieties, it is impossible to determine exactly how, where and in what way the start of the line. With our feet on the ground and going to the practical, we are going to see how to treat your daughters, granddaughters and other descendants correctly.
The truth is that, regrettable as it may be, the cannabis seed business is perhaps one of the most deceptive in terms of its marketing, using techniques and advertising that sometimes border on the surreal, unfortunately for the novice or experienced cannabis grower Anyone who has cultivated a few times or has been buying seeds for some years will have been able to see how this market has evolved, from the 3 or 4 Dutch banks that we all know and that began to commercialize narcotic cannabis grain on a global scale, to the eyes of banks that exist today, the vast majority of Spanish origin.
We do not really know why, but the reality is that almost from the first moment this “mythological marketing” has been used when putting varieties on the market, new or not, perhaps encouraged by the illegality of cannabis cultivation (to produce seeds must be cultivated) and the prohibition of their consumption. In any case, common sense tells us that it is highly unlikely that each and every one of the more than two thousand varieties that have appeared in recent years are “new”, but then, if they are not new, what are they? G13 bud in all its glory
The family grows
The reality is that many of the new varieties that have appeared are very similar to each other, although their description or genetics change, in addition to the lack of stability that they mostly present. This is due to different reasons, but perhaps the most important is the widespread use of Silver Thiosulfate a chemical compound that transforms female cannabis into males, and that in the absence of any breeding process, ends up homogenizing the genetics making each time there is less difference between varieties.
On the other hand, and in the present case, the famous G13 predates the appearance of sexual inversion techniques in cannabis and that is why the pure variety was never reproduced in the form of a female clone, being crossed with different parents with the intention of preserving their genes in the offspring. Later those hybrids continued to cross over and over with the fashionable varieties, giving rise to more than 200 varieties that contain G13 to some extent.
As we indicated in the previous issue, it would be almost impossible to determine an optimal nutritional regimen for each of them, and even grouping them into categories of the indica dominant or sativa dominant type the task continues to be complicated, so we are going to do it using a very little classification. habitual, based on some unique characteristics of the original hybrids that frequently appear in the offspring. In this way, after identifying the group to which the G13 hybrid that we are growing belongs, we will be able to apply the appropriate nutritional regime for that variety in each cycle, vegetative and flowering.
Thus, we have, on the one hand, those varieties that start from the crossing with Super Silver Haze on the other those that carry Skunk and finally those that present Afghan or Kush dominance. Let’s see how we can do to classify our variety and thus determine its optimal nutritional parameters. Cannabis plant variety G13 growing
Where is Wally?
Cannabiculturists with more years of experience will have noticed one thing, not always evident and not always detected or its reason explained: Different varieties have the same reactions to certain stimuli, these being clearly identifiable reactions throughout the different crops. For example, surely more than one cannabiculturist will have had plants that at the beginning of flowering always have the central leaflet of the leaves of 5 to 7 leaflets twisted to the right. If this phenomenon caught the attention of the cannabiculturist and he investigated the issue, he surely reached two clear conclusions: It only happens if the pH of the soil or the nutrient solution is above 6 and when the variety contains Jack Herernon-feminized from Sensi Seeds prior to 2000. In fact, it was this variety that passed that recessive character to the offspring until it was corrected, we suppose, surely using the Dinafem selection in the form of Moby Dick. In this way we can identify if a certain variety contains Jack Herer pre 2000, regardless of what the catalog says about its composition.
Precisely, as a curiosity or strange coincidence, the year 2000 was a year in which some varieties also historical or at least recognized as “different” were “improved” because of some remarkable characteristic such as Kali Mist, Northern Lights or the same Jack Herer. In principle, these improvements of the year 2000 tried to correct these small inconveniences that are really phenotypic manifestations of a recessive character, although cannabis growers who have worked with the original versions may prefer them, since there are notable differences in production and all have lost something. stability. It is also true that the current version is not exactly the one from 2000, since in the current season batch small nuances are once again noticeable, especially in the flowering time.
In the case at hand, the descendant varieties or those that contain G13 in their genetics also show signs that reveal their presence, although this is not a determining factor either and there may be individuals that have G13 among their ancestry and do not show these recessive characters.
The right diet
A detail that should show every variety that contains G13 in a percentage higher than 25%, regardless of the rest of its components is the discoloration of the main stem from the peak flowering stage, which happens both with high and low pH and for The plant is very well nourished as long as we grow indoors with less than 1,000 Watts per square meter. Outdoors it also happens when plants receive less than 8 hours of direct light. This characteristic is usually accompanied by a deep purple coloration of the secondary branches at the moment when night temperatures or when the lamps are switched off below 18º C. However, this does not affect the production or the density of the CogollCs.
To know if our variety contains G13 x Skunk, we must observe their reaction once the plants reach sexual maturity, that is, they show pre-flowers even when they are kept in a vegetative state. If we water them with a pH below 6 and the main leaves acquire a very dark green color, we can say that the G13 x Skunk genes are in it, in which case from that moment on we will have to maintain an output pH number of irrigation water) of 6.4 as a minimum when cultivating in soil and 5.8 in hydro to avoid the hypercolouration of the leaves that is due to a genetic defect, which is responsible for that with a low pH system nutrient transport and fixation do not function properly, in particular by inefficiently accumulating iron and nitrogen in the main leaves.
This produces two negative effects: It is very easy to burn the plants if we add too much nitrogen or the soil is very loaded with this nutritional element. In addition, if this “overdose” does not occur, these leaves will quickly yellow as soon as flowering begins, falling by themselves, while the small leaves that are still born between the buds continue to store Iron and Nitrogen, which causes that the herb once harvested and dried is an expectorant and it is difficult to achieve that it does not make you cough, even with a long curing process.
If the hybrid we have planted is a descendant of G13 x Super Silver Haze, things are somewhat more complicated, although there are also some nuances that can identify its presence. To begin with, it is in these hybrids that the “impersonation” that we mentioned in the previous issue is most noticeable. For those who have not read it, we remember that we mean that although they maintain an indica growth pattern, including phenotype and flowering and ripening times, they provide aromas, flavors and above all clearly sativa psychoactivity. We also refer to the appearance of the plant, which begins with broad and rounded leaflet leaves, typical Afghani, narrowing and refining little by little as the flowering progresses, to finish with the usual sativa finish, that is, slow maturation and slight stretching of the buds (more the less light power they receive).
