The original seeds of the Dutch banks are expensive because to produce it requires them a great work. One is not to take to a female anyone and to cross it a male to remove seeds. In order to produce the best seeds two pure races make lack. The banks of seeds must be selecting, year after year, the best plants of a variety to cross them to each other. Throughout several generations they stabilize the variety so that all the plants are similar to each other. When the variety is stable seed hundreds of seeds and the best female selects itself. This female will cross itself a male of another selected pure and stable variety through same procedure. All this process of selection and hibridación can last several years and implies the germination of a few thousands of seeds. With this work very powerful varieties, homogenous and productive are obtained. Cañamones produced by banks of seeds has several advantages. On the one hand, you know exactly that varieties plan Planting good seeds, all the females will be powerful and place well. anvil and, therefore, which you can harvest. Secondly, most of the Dutch varieties they are F1, which means that they are hybrid of two pure races. Seeds F1 enjoy a vigor and a special strength, call hybrid vigor, that makes them produce until a 25 percent more of cogollos. The seeds that a plant F1 produces denominate F2 and no longer they have the hybrid vigor. Thirdly, seeds F1 usually give rise to quite homogenous plants, that is to say, seemed to each other. All the plants of a variety will be similar and be mature and ready to harvest more or less at the same time. This does not happen to the seeds F2, that give rise to very different plants to each other, powerful ones and other no.
I can cultivate with homemade seeds?
The seeds that leave in the cogollos of your plantation do not have anything of bad. Them they can leave good plants, but all the plants that leave will not be good. The main disadvantage of the homemade seeds is that there is no quality assurance of the grass. Seeds will give good plants and other no. If we are not very demanding with the quality of the cogollos or if we have space sufficient as to seed many seeds and to select only the best plants, the homemade seeds can serve to us. In fact, if we planted a variety year after year and are crossing the best plants, we will take control of our own race in a few years. He is crucial to select the best plants to avoid than the species degenerates and loses its content in THC. If on the contrary only there is space for few plants and you want to remove a harvest that allows to smoke all the year you look for Dutch seeds. The seeds of the same country or homemade are very dangerous. Some take too much in blooming, others cogollan little, are you even have left dwarves and that as soon as they throw resin. With seeds of good varieties and a little taken care of in the culture, the powerful grass practically is guaranteed.
Pure race of marijuana (fragment)
The pure races are those in which certain characteristics are always present. This does not mean that all the plants are exactly equal in all the aspects, but will maintain a certain uniformity. That is to say, although some plants are higher or earlier, most of them it will enter its characteristics within certain limits. An important advantage of the pure races is that the seeds produced from males and females of that pure race do not lose quality like when we make a crossing between seeds F1. The phenotype of a plant (its external aspect) comes dice by its genotype (its genetics) and by the environmental conditions. Two seeds with the same genetics cultivated in different conditions give rise to two plants with different aspect. We can obtain a pure race in which all the plants are exactly equal in everything? By all means that no, the genetics is too complex as to be able to fix all the characteristics of a plant. What yes we can do is to fix some characteristics, specially those that interest to us more like cultivators. One is to obtain a general uniformity in those characteristics that we want that they define our species. Let us say that we want to make a race pure of early flowering. The speed of flowering is a characteristic that comes determined by a pair from genes (in fact it is probable that it comes determined by several pairs from genes but we simplified it so that is understood more easily) contained in the chromosomes of each cell of the plant. The chromosomes come in pairs and in each member of the pair one of the genes lodges that indicate the speed of flowering. If we have one hundred seeds and we planted them we will see plants that mature before and other that mature later. If there are one hundred plants, we can consider that we have two hundred genes in charge to define the speed of flowering. Each one of these genes can slightly be different, but to us to only it interests the gene us that gives the earliest flowering. Ideally, all the genes of speed of flowering of the race would have to be he himself gene. A race will be as much purer and homocigótica for the early flowering whichever greater frequency of appearance has the wished gene.
