If you want to get a crop of very dense and full of resin buds, the type of pruning you do plays a very important role. The two best-known types of cannabis pruning are apical pruning (known as Topping) and FIM pruning (known as Fimming).
We tell you what both methods consist of.
Apical Pruning or Pruning Topping What is it?
The apical pruning or topping consists of cutting the tip of the main stem of the Cannabis plant.
Possibly it is the high stress training technique, or HST, that is most used in indoor and outdoor cultures.
Cannabis that develops naturally has a similar appearance to that of a Christmas tree, with a central stem and several lateral branches. With this morphology, all areas of the plant will receive the same dose of light when the sun is crossing the sky.
However, indoors things change. In indoor cannabis crops, light is generated by growing foci that are fixed and do not move and that is above the plant. This means that the natural form of the plant is ineffective, unless we carry out large crops with the SOG or See of Green method.
The most used method to prune Cannabis
Cannabis apical pruning is the procedure most used by professional growers as it is able to increase performance considerably. It is also used by many indoor growers with crops made up of a few plants, instead of grouping as many as possible.
As the terminal bud is cut, this method promotes the development of two main tails and also stimulates the development of secondary branches.
With the apical pruning, we invert the shape of a Christmas tree to get a greater dose of light to penetrate the plant.
When we remove the dominant apex, the growth hormone is distributed more homogeneously by all the shoots.
Having small plants but lots of buds is ideal for any grower; indoors because vertical space is usually scarce, and outdoors, because bushes are more discrete than tall trees. The apical pruning is perfect to control the cups of your cannabis plants.
How the Apical Pruning is done
The way to do the apical or topping is to make a clean cut at the tip of the main stem with scissors that have been previously sterilized.
We must cut the tip 100% so that the tail will become two. The best of all is that we can carry out this technique several times, that is, we can multiply the tails.
The vast majority of professional Cannabis growers agree that apical pruning is the best for the vegetative development phase of the plant.
The ideal time to do pruning is a topic to discuss.
It is usually agreed that it should be carried out early, when the plant has 3-5 knots. However, there are growers who say that you should wait a little and do it after 30 days, or until the plants are at least 30cm high, before pruning.
As the topping is a high stress procedure, the plants will require some time to recover. Ideally, wait around 1-2 weeks before continuing to carry out pruning or training techniques.
Pruning FIM or Pruning Fiming What is it?
Fimming is a high stress procedure that increases crops, and is similar to topping, although it has a number of variations.
As with the apical pruning, the objective is to increase the number of main tails, but instead of duplicating them, with the FIM pruning, more than 4 new tails can be generated. This procedure is advised in micro-producers who only want to have 1-2 plants.
With this technique, the secondary shoots will take advantage of the growth hormone that was previously used to "feed" the main stem.
Most growers think that FIM pruning is a little less effective than apical pruning to decrease stretch. A cannabis plant pruned by fimming develops a lot, but has more main tails.
How the FIMMING is done
In the same way as topping, it is better to perform this procedure when the vegetative development stage takes place. However, unlike apical pruning, this procedure has a less precise approach.
To be more explicit, FIM comes from the acronym of the expression "Fuck I Missed" which means "Fuck, I failed"
With this method, it is preferable that 75% of the tip of the main stem be removed with the fingers to exert a clean cut of the entire tip.
Aesthetically, it is very beautiful, but it is effective. At least, 4 new shoots are going to emerge after one or two weeks. Occasionally, up to a maximum of 8 can be generated. In addition, secondary shoots will gain ground at the same time.
Although some deformed fan blades will emerge, the FIM method is not very different topping. The time that we must wait for the plant to recover can range from 1-2 weeks.
Prune the Cannabis plant to obtain greater harvests
Are you looking to boost your crops to the fullest? Possibly, you will have to be prepared to combine some pruning techniques. The apical pruning or the FIM alone will improve the results, but there are ways to boost the harvests even more. If you are looking to get a few extra grams, you should make an extra effort. Fusing the following two methods can be the best way to achieve incredible harvests.
The Lollipopping technique
In short, the lollipopping is about getting rid of the lower shoots of the marijuana plant. With this technique, energy from the plant is concentrated in the creation of dense buds, instead of spongy buds.
This technique is usually carried out at the third week of the flowering period. It is pinched with the fingers instead of cutting with scissors (although it is already according to preferences). ScrOG growers usually remove any growth below the mesh so air circulates better and concentrates all the energy in the cups.
The SCROG Technique
The pruning techniques that we have named are further enhanced if the ScrOG or Screen of Green method is carried out (green screen).
The ScrOG method is the highest expression of high yield Cannabis cultivation. You need a mesh that is placed in the culture space. The grower has to arch and fold the shoots of the plant so that they fill as many holes in the mesh as possible. It begins in the vegetative stage and is followed until the beginning of flowering.
The Limitations of the Apical Pruning and the Fimming Method
The apical pruning and the fimming increase the time that the cannabis plants in the phase 18/6 of the vegetative development. If these techniques are performed, a vegetative phase of 4-6 weeks must be prepared.
Another negative point of these methods, which is related to the development of multiple queues. Marijuana plants can develop very heavy tips. If the ScrOG technique is not used, bamboo sticks may be required to support them.
Here’s what you need to know before seeing your regional medical dispensary:You may need a physician’s recommendation, medical cannabis certification, and/or whatever appropriate documentation is needed by your condition. Typically, you need to be 18 or older to be eligible for a medical authorization, but exceptions may be made in some conditions for minors with especially debilitating conditions. You will usually enroll with a medicinal dispensary. This is to keep your medical cannabis recommendation or certificate on file for legal and regulatory purposes. There’ll be a waiting room. This will be to control the flow of patients and product, but a straightforward dividing wall gives patients solitude and direct one-on-one contact with a budtender to discuss medical problems. This process can help budtenders and patients monitor effective medicine in addition to have a living listing of manufacturers and goods for future reference and follow up. Medicinal dispensaries usually allow you to smell and examine the buds prior to purchase. This may differ from state-to-state.
Yes, municipal approval is required before the AGLC will issue a retail cannabis license. Applicants must get in contact with their planned municipality to find out requirements concerning municipal retail cannabis legislation, zoning requirements, land-use limitations, and place requirements concerning how close a retail shop can be to a provincial health care centre, school, or parcel of land designated as a college book.
Keep non-medical cannabis legal Adults who are 19 decades or older are able to:Have up to 30 gram of authorized dried cannabis or the equivalent in their own person. Share up to 30 g of legal cannabis with other adults in Canada. Purchase cannabis goods from a Yukon Liquor Corporation licensed retailer. Grow up to four plants per family. It’s illegal to present non invasive cannabis to anyone under the age of 19 and for anybody below the age of 19 to have any quantity of non-medical cannabis in Yukon.It is illegal and dangerous to drive while under the influence of cannabis or other intoxicants.
