What is the difference between cannabis seeds
The right choice of genetics is crucial that you can ultimately enjoy the harvested marijuana flowers. Therefore, not only good cannabis seeds are important for rearing. It also depends on what genetics is and what you want to do with the seed. If you e.g. has a strong sativa-heavy genetics, then the flowering should be initiated after three weeks because of the strong growth force, if the young plant on the stem is not even lignified. The plant should already be placed in an approximately seven to eleven liter pot or just placed on the mat or on the flow table or the Aquafarm or the Aeroponic system. There are really some ways to make the plants bloom.
But back to the Sativa Genetics: This can develop a tremendous vigor and zoom from the just 15 cm in size at the beginning of flow on well over a meter. Not all Sativas have this urtypical growth power. There are also many genetics with Sativa and Indica shares, whose growth is more difficult to assess. It should be resorted to the information that you get from the breeder. Unfortunately, these are somewhat sparing with information, even if they sell good cannabis seeds. Depending on cultivation technique and ability, the plants also differ significantly in their results.

Note differences in the growth characteristics
Sativas should at least be sent quickly into the flower. With mixtures of Sativa and Indica one should wait a little longer, until the plants are 20 to 25 cm large. With strong Indicas you should wait even longer, until they are about 30 cm tall or larger. From experience, it is optimal for the Sea of Green, when the plants are about 80 cm tall. Sea of Green is understood by many to be a lot of plants in a small space, all growing with a main bud. They form a strong flower stem, the side shoots are sometimes even removed.
In the "Indoor Weed Cultivation" plant, the term Sea of Green (SoG) is used for a cultivated area that is a lake of green. Wherever you look, you can see from the actual flowering only in the green, there is no ground to see. The plants occupy every cm² with their leaves, but should not proliferate too much, since the results then suffer again. However, the shoot tip can also be shortened so that the plants branch. The important thing is that really every cm² filled with green but not crowded. But more on that later.
These recommendations, for the initiation to flowering, are aimed at plants of about 80 to 100 cm in height. Otherwise, smaller or larger seedlings can be grown. There is no universal statement here and elsewhere in the book that can always apply. What exactly are good hemp seeds, therefore, it depends on your point of view.

Form the plants
If you notice that your seed plants really do not want to grow with the side shoots, you can take the top with the fourth or fifth leaf level. That's only one cm above the top pair of leaves. Now the plant has to grow with two shoots. Again, the tip can be taken once again, when these shoots have opened their first pair of leaves. Now the seed plant grows with four shoots at the top and the lower two side shoots develop very strong. Not every shoot develops really vigorously, but the plant will produce three to six main shoots and will not grow like a stalk but rather like a bush. So you can fill the area significantly better in the flower and must burn much less good cannabis seeds. So also mother plants bushy, so you can cut more cuttings.
But if the plants grow vigorously with the shoots, then the tip should not be cut. There are even strains that grow so bushy that you could even clear something. It is purely a matter of taste, how tall or bushy the plants should become. The genetics are fundamentally different, but the grower has a big impact on strains that he already knows. That is why it is so important that there are good cannabis seeds, which have the same properties at the next purchase. It is just as important to find the cannabis seeds that are good for you. For someone else, the same cannabis seeds may not be good, because not everyone has the same genetic characteristics.
Some decision criteria for good strains would be the yield, effect, taste, time to harvest, space requirements, THC content, (un) sensitivity, indoor or outdoor suitability, climatic zones or the growth characteristics.
