Growing cannabis at home is not something too complex and there are no shortage of guides that can be found at the click of a button on the Internet. However, there are some basic questions that repeat themselves more than once. We gathered the most prominent 6 from the magazine forum and discussed them one by one.
Growing Cannabis at home is undoubtedly a fun, enriching, and highly satisfying hobby: in less than 16 weeks you can experience a complete life cycle of the plant on its four stages - germination, growth, flowering and harvesting.
For many, this is the first time they have been involved in a cultivation process. In such cases - and after a study In growth manuals Online And forums, At their head Guide to growing Most often called in Israel - the tower sometimes finds itself with a number of basic, but important and relevant questions.
We have collected the most frequently asked questions from 6 "Beginners Forum"Of the magazine, and answered them for the curious.
1. When, how and how many farms?
Proper irrigation is a very important part of the growth process: The iron rule for raising cannabis in the soil is to maintain the cyclicity of moisture and dryness in the growth medium. In most cases, irrigation is done every two or three days, but of course it is recommended to monitor the situation regularly, since it also depends on factors such as plant age, variable temperature, humidity in the room and so on. The moisture level of the substrate can be checked by carefully inserting a finger into the upper layer of the growth medium. If you feel a little moisture, there is no need to water. If dry completely, watering.
In terms of the manner and quantity of irrigation, assuming that this is a manual irrigation, it is desirable to water the entire surface of the soil gently and without the flow of water produced from holes in the ground. A good sign to end the irrigation is the seepage of the water through the drainage holes at the bottom of the pot. The recommended quantity will be about 20% runoff (water that leaked from the bottom) for each irrigation, meaning that for every 5 of irrigation, at least one liter will be drained. However, there is no need to make measurements on every irrigation. Maintaining a steady flow of water from the drainage holes will be sufficient.
As opposed to watering a potted plant in the ground, irrigation in a hydroponic systemHydro growth) Is a process that depends on the specific tumor system and the type of growth medium used. In any case, it is recommended that early growers grow at least one cycle in the soil before experimenting with hydroponic crops.
2. What flower pot size is recommended for growing cannabis?
The growth of the plant in cannabis cultivation is of great importance to the growth process. On the one hand, a large living space for the root system will ensure efficient growth and intensive growth. On the other hand, in most cases there is a space constraint, so there is a need to settle for a flower pot that is smaller than the ideal.
The general recommendation for potted volume will be to ensure at least 3 liters for each month of increase in cases of lack of space, or 6 per gallon for each month increase when there is no space limit.
For example, for a tumor that is supposed to last about 4 months, the cannabis will need a pot with a minimum volume of 12 of soil, with the ideal being 24 (or more).
Of course, even when it comes to hydro-growth, the situation is different and depends on factors such as the nature of the system and the growth platform. In principle, it can be said that in the vast majority of cases, plants growing in a hydroponic system will need a smaller plant volume than an increase in soil.
3. When to start fertilizing, what fertilizer should be used and how much?
When cannabis is grown in the soil, it is often not recommended to add fertilizer during the first few weeks after sprouting. The concept is to irrigate the plant with clean water only. After two or three weeks of growth, fertilizer can be added to the irrigation program.
The reason for waiting with the fertilization stage is that when the plant is in its early stages of development it needs a very small amount of nutrients to ensure normal growth. Most types of nursery land contain elements and elements that will suffice for the first weeks of growth of cannabis, so there is no need for intervention at this stage. However, measured and controlled feeding probably will not cause serious damage.
When the plant is already several weeks old, you can start feeding it with the appropriate fertilizers. In most types of fertilizers, the recommendation will be to start fertilizing the dose of 1 ml fertilizer on each 1 liter of water and increase the quantity over time according to the development of the plant and its reactions. However, attention should be paid to the recommended dosages of the manufacturer and always to examine how the plant responds each time the fertilizer is increased by irrigation. In contrast to the cultivation in the soil, in detached bedsteads ("hydroponic" crops) should be fertilized from day one.
In terms of types of fertilizers, it is possible to purchase "general" fertilizers (eg, "Akogan Perfect", for example) in each nursery at a price of about NIS 50. This fertilizer will in most cases provide all the nutrients needed for a complete life cycle of the cannabis plant. Many growers would prefer to choose "dedicated fertilizers" - which can be obtained mainly at the "grouse shop" Hydroponics stores. They will of course Much more expensive And will offer additional packs of enzymes and additives as part of the overall package.
The best recommendation for early growers is not to "disperse" with the purchase of products in branded packages and explosive names, but to stick to the basic line of these fertilizer companies - which will consist mostly of base fertilizer for the growth period, basal fertilizer for the flowering period, and possibly another PK (phosphorus and potassium supplement) ) For peak stages of flowering.
These base fertilizers contain all the necessary elements for cannabis and are supposed to cost no more than 200-300. After experiencing a cycle or two with the base fertilizers, the grower will be able to get a better indication of the need to combine other additives with the irrigation solution.
4. What type of bulb is required for several plants?
Early growers sometimes mistakenly think that the intensity and power of the bulb should match the amount of plants they grow, but when it comes to artificial face growth, the central parameter to examine is the surface area we have. For example: on an area of 1 sqm can be grown only one plant or grow also 12 and more - on the same lighting supplier.
The following is a general assessment of bulbs and compatible growing area:
A light bulb of 150w will be suitable for an area of 50 cm2.
A light bulb of 250w will be suitable for an area of 65 cm2.
A light bulb of 400w will be suitable for an area of 80 cm2.
A light bulb of 600w will fit into an area of 1.
This calculation refers to high pressure discharge (HID) bulbs. These growth bulbs are considered to be most prevalent in the market. They contain gases and have a very high potential for light production. There are two types of HID bulbs that are widely used in cannabis towers: MH and HPS. The essential difference between them will be the light that the light will produce:
Metal-halide bulb (MH) - will produce a white-blue light that will be more suitable for the vegetative stage (the growth stage) of cannabis.
(HPS) - produce a yellow-written light that is more suitable for the reproducible stage of cannabis.
The disadvantage of these bulbs is quite high power consumption and the intense heat they emit. However, today there are alternative light bulbs in the market that cover these shortcomings:
Fluorescent lamps - Grow Cannabis with fluorescent bulbs is recommended mainly for use for cuttings and seedlings in the early period of growth - these take good advantage of the blue light produced by the bulb and the minimum heat it emits, enabling very close installation of the bulb to the plant. The use of florescent bulbs during the flowering phase is less recommended due to its intensity and limited light permeability.
LED lamps - LED lighting allows you to choose between blue spectrum lighting and red spectrum lighting. This makes it possible to design a bulb that is precisely suited to the needs of the plant so that there is no need to replace bulbs during the growth and flowering stages and you can run an entire growth cycle with the same lamp - the blue light will be used for growth and red light for the flowering stage.
Despite all the important advantages that LEDs provide, they also have a few negative points to consider: first these bulbs are significantly expensive fluorescent lamps and HID. The second disadvantage is that the market is flooded with models from different countries and manufacturing companies, making it difficult for growers to choose the right bulb. In addition to reports of successful tumors and images of impressive growth rooms used in LED lighting, there are quite a few stories of failed crops. If you decide to choose a tumor with LED bulbs you should not save. It's a pity to buy a model that is significantly cheaper than the others but at the end of the day simply will not do the job.
In terms of covering surface area of tumor bulbs, there is a rule of thumb recommending 50 watts for each 10 cm2 of tumor area. The rule is roughly consistent with the surface coverage estimate of the above-mentioned lighting, and can also be used for selecting a fluorescent bulb or LED. In any case, it is advisable to consult the manufacturer's recommendations in any case.
5. When is cannabis ready for harvest?
Although there are quite a few Related Directories, Which simply explain how it is possible to know when cannabis is ready for harvest, it seems that many growers still struggle on this issue and find it difficult to determine the right harvest date.
The most common and most commonly used method for timing the harvest is to trace the color change of the 'The top pages(Which are also called "hairs" in the wake of their appearance). This is a very simple method that does not require any accompanying equipment to perform it. With the transition of the plant from the growth period to the flowering period, the "hair" will change their color from white to gray to orange-brown.
Cannabis flower that at least 60% -NNUMX% of the white hairs in it became brown orange will in most cases be harvested.
A second method is an exam Trigonometry, The resin glands that cover cannabis. In order to test the trigemes thoroughly, basic optical equipment is needed. A standard magnifying glass will not always allow the tower to obtain a clear enough picture of the trichomes, and therefore it is recommended to purchase a miniature microscope with at least 30 magnification and make sure the microscope comes with a built-in flashlight. Its average price is between 10 and 35 USD and is well worth the investment.
The single trichomonas resembles a fungus and its top will change color over time. Initially all the trigeminal heads will be clear and transparent but later some of the heads will turn a bit murky and get milky. At the end of the process an amber-brown color will be obtained.
The timing of the harvest according to the color of the trichomes has implications for the psychoactive effect of the end product and it is customary to associate the colors with certain effects. When a small portion of the trichomonas heads become milky, a light, uplifting and energetic effect will be created. Making the harvest while half of the triglycerides are halogenated and half transparent will give a less stimulating and slightly more physical effect. Cannabis harvesting When almost all trichomes have already been browned, the final product will have a more "sticky" physical effect.

6. When to move from a growth period to a flowering period?
The cannabis plant has two growing periods that are important to recognize: the growth stage and the flowering stage.
During the growth period, the plant should be provided with constant light and continuous 18-24 hours a day. During this period of growth will develop a system of branched roots, sturdy stem and strong branches, that will help hold the juicy flowers.
In the second stage, the flowering period, the plant will begin to produce flowers at each point of branches branching. Cannabis is a short day plant (or rather a long night), meaning that the plant begins to bloom when the number of hours of darkness is more than 10 consecutive hours (depending on the species).
In nature, we can see that the process of cannabis blossoms begins to take place towards September, when the days begin to shorten and the darkness takes up a larger share of the course of the day. The growth of the flowering face is timed by the grower himself by switching to a lighting cycle that includes at least 12 continuous hours of darkness a day.
There is also a difference between the periods in terms of composition of the plant's nutrition: At the growth stage cannabis needs relatively large quantities of nitrogen, and during the flowering stage it still needs a lot of nitrogen, but it also needs higher doses of phosphorus and potassium.
In raising an interior there is no problem in attracting the growth period for long periods of time. On the face of it, we would like to have as much plant as possible, since a large plant would give a large crop. This is not necessarily true and therefore arises the question when is the best time to put the plant to the stage of flowering?
A common misconception of novice breeders is not to calculate the size of the free space left to the plant, since at the flowering stage the plant continues to grow high. When the plant is too high, there may be overcrowding in the tumor chamber. In such a situation the plant slows its growth, and humidity rises - which can cause For appearance of mold and pests.
There is no unequivocal answer to the question of the timing of the transition to the flowering stage, depending on a number of factors: the variety, the space in the growth area, the age of the plant and its health, the substrate and the growing system (soil / detached soil), the culture technique (SOG, At the disposal of the tower itself.
The rule of thumb that will be appropriate in most cases is to examine the appearance of the plants from the sides and from above and switch to a light regime of 12 / 12 when they reached half their final designated size. Note: When moving to the flowering stage, make sure that the plant is essential and healthy. If the plant is infected with pests, suffers from a lack of nutrients or is in stress for some reason, it is desirable (if possible) to continue the growth stage until the problem is treated and move to the flowering stage only after the plant has improved.
