Topping / Pruning
It is customary to cut the top of the plants, to force plants to develop more tops and branches. If you prefer a large dominant buds or have limited space, you should not cut the plant. The advantage of cutting the plant is that the yield will be considerably larger.
You may want to cut the top of the plant when they have developed 3-5 leaf sets. But this can also be done later, if you have enough space.
Plant before being cut.
Plant after it is cut.
Here are the results after 2 days.
Pruning
It is an eternal debate whether it is necessary or not. As a starting point it is not necessary, but in some situations it may be wise.
If you choose to crop plants, it is best to do this right before you put the plants in bloom.
There is a widespread perception that the flowering plants need light to direct the shoots. Therefore, many recommend cutting off the large leaves, as in the situation below.
Leaf that covers the branch.
The leaf is now removed to get the branch to get more light.
This may work well in some situations. To remove a leaf like the picture in my opinion is not necessary, since it only covers a small shot. The leaves use the leaves to capture sunlight. This shot will probably be quite small anyway, unless the plant will be growth phase in a month or two. As is the compromise, you can either wait to remove the leaf towards the end of flowering.
In the book "Marijuana Botany"said Robert Clarke, the following:
"The large fan leaves Have a Definite function in the growth and development of cannabis. Large leaves serve as factories for the Photosynthetic production of Sugar and Other Necessary Growth Substances. They do CreateObject shade, But at the sametime thay are collecting valuable solar energy and producing foods That Will Be extremely hum the floral development of the plant. Premature removal of the fan leaves May Cause stunting Because the potential for photosynthesis is Reduced "
You must consider this with regard to how large plants are and how much space you have. Large leaves on a plant can shade the light to another plant, then it may be wise to remove the leaf, so that both plants get about the same amount of light.
It may make sense to prune the plant completely in the bottom. Shoots that grow here are not as likely to develop good, since they rarely get enough light. So, if you choose to remove these plants will not spend more energy on the top shots. This will not provide greater benefit in total, but you get a dividend of greater quality (several big shots). The lower shoots a fine to use as cuttings.
A more radical approach is to cut away all the lower growth, ie, all the young shoots and leaves that do not have the optimal position in relation to the light. It will mean that the top shots will be even bigger and nicer. Depending on when you cut off the top of the plant, you will get 6-8 big shots, instead of 12-16 less. This will usually be sensible to do in two innings. First, cut the bottom part of the plant, so you can start flowering, and after 2 weeks can flatly trimmed again.
A severe pruning that this is only sensible to do if you either will get the plants to fill up less space, is if you are only interested in growing perfect and big top shots. It stresses the plant when it is cut so many leaves off, so the total dividend will be less.
The many disadvantages of crop plant too much. As an ending comes a quote from Robert Clarke "marijuana botany":
"Leafing is one of the most misunderstood techniques of drug Cannabis cultivation. In the mind of the cultivator, several reasons exist for removing leaves. Many feel that large shade leaves draw energy from the flowering plant, and therefore the flowering clusters will be smaller. It is felt that by removing the leaves, surplus energy will be available, and large floral clusters will be formed. Also, some feel that inhibitors of flowering, synthesized in the leaves during the long noninductive days of summer, may be stored in the older leaves that were formed during the noninductive photoperiod. Possibly, if these inhibitor-laden leaves are removed, the plant will proceed to flower, and maturation will be accelerated. Large leaves shade the inner portions of the plant, and small atrophied floral clusters may begin to develop if they receive more light. In actuality, few if any of the theories behind leafing give any indication of validity. Indeed, leafing possibly serves to defeat its original purpose. Large leaves have a definite function in the growth and development of Can- nabis. Large leaves serve as photosynthetic factories for the production of sugars and other necessary growth sub- stances. They also create shade, but at the same time they are collecting valuable solar energy and producing foods that will be used during the floral development of the plant. Premature removal of leaves may cause stunting, because the potential for photosynthesis is reduced. As these leaves age and lose their ability to carry on photo- synthesis they turn chloro tie (yellow) and fall to the ground. During chlorosis the plant breaks down substances, such as chlorophylls, and translocates the molecular com- ponents to a new growing part of the plant, such as the flowers. Most Cannabis plants begin to lose their larger leaves when they enter the flowering stage, and this trend continues until senescence. It is more efficient for the plant to reuse the energy and various molecular components of existing chlorophyll than to synthesize new chlorophyll at the time of flowering. During flowering this energy is needed to form floral clusters and ripen seeds."
