How to grow

Growing Marijuana Indoors

First be optimized the carrier or cabinet where it is to grow, you must create the right conditions. The more tightly sealed, insulated and sealed to better control the fundamental factors: light, water, temperature, humidity, substrate and nutrients.

Light: 18 h growth period; flowering time 12 h.

Water: pH 5.5-7 (optimum 6.5). Monitored must not oscillate abruptly.

Temperature: 22-28 ° C; optimum 25 ° C during illumination period and 18 ° C during the dark period.

Humidity: 60% during growth; 50% during flowering.

Substrate: A choice (coconut fiber, peat, black peat presterilized …).

Nutrients: A choice: organic, mineral. There are many specialized companies such as: “Canna”, “Ghe”, “Bio” …

Germination: There are numerous methods for germination: rock wool, seedlings, peat Jyffis … A possible method is to germinate seeds in cotton wool soaked in water. For this, the seeds are placed on top of a layer of moist cotton and covered with another layer on top.
Approximately five days after the seed will open, from which will emerge a white “rabito” root. This is the time when the seed is more delicate, so it took very carefully, be placed with the root down a seedbed with previously placed some slightly compressed earth and then covered with more soil. Stimulators of roots are very effective in this early stage of the plant. Eg Rhizotonic, Hesi Root Complex …

Growth: the focus to 18 h of light and 6 h darkness is placed. This is the stage where the plant has all its supporting structure (flares), therefore promote growth by the use of a growth fertilizer (nitrogen rich: Ex Terra Vega.). Only within two weeks after germination rate of subscriber and up to 3 times per week dissolved in irrigation water began.
After about a month the plant will reach a height of about 30 cm, which indicates that is ready to move to the flowering stage. The subscriber growth will continue until the pre-flowers though it is passed to the flowering stage, in order to avoid future shortages of nitrogen appear.

Flowering: In this phase the focus to 12 h light and 12 h darkness stands. During this stage the plant no longer produces new shoots grow only those you already have. About two months ended flowering plant depending on the variety. It is advisable during the course of this to provide a specific fertilizer flowering phase (rich in phosphorus and potassium Ex. Terra Flores) at a rate of up to 3 times a week. During the 4th or 5th week of flowering requirements increase phosphorus and potassium so it is interesting adding a bud enhancer (ie. Pk 13-14). Finally 2 weeks before “cutting” adding fertilizers only water up to 2-3 days before the “cut” where the risks are also interrupt will be restricted.
The plant is considered mature when 70% of the pistils turn brown. Not every plant has since matured at the time, then can be harvested ripe and book parties “green” to continue maturing. Normally the “indica” varieties grow less but usually bloom earlier and produce more, otherwise the “sativa” varieties tend to be very high and flowering occurs later.
Drying and curing. This part is as important as the above process. The location must be well ventilated dim addition to meeting certain conditions of temperature (15-18 ° C found) and humidity (must not exceed 60%). The plants were cut by outbreaks to hang upside down. It can be interesting slightly thicker flowers shred in order to avoid any attack by molds. The process is considered complete when a branch breaking sound “crik” (approximately 15 days). Control of pests and diseases. It is one aspect to consider, as they can cause a decrease in crop yield and quality of the same, hence the importance of carrying out a good prevention. To do this, it would be interesting to apply an insecticide and fungicide approximately every 15 days, spraying the plant and therefore the beam on the underside of leaves during the dark period, in addition to keeping a full visual control of the plants. In the market there are biological, more respectful of the plants because they come from plants and microorganisms, or chemicals that are often more effective when the pest is already installed.

What is pH? The pH is a measure of the acidity of a solution. The solubility of plant nutrients, especially phosphorus and trace elements (iron, manganese …) depending on this value, finding the optimal value in the range 5.5-6.5. The importance of control of this measure is that certain elements in “extreme” pH values ​​(outside of that range) are under insoluble forms for plants, so although the existing actual concentration may be high plants are not able taking them and they may be deficient. (Ej. Chlorosis …)

Ventilation. It can be considered that there are two types of ventilation circulation (interior air movement) renovation (renovation of the interior air). The flow is solved by installing a wind getting fan effect avoiding air stratification. In an atmosphere calm (no wind) are forming layers of air depending on the temperature and concentration of gases, forming a thin layer around the leaves that is enriched in oxygen and depleted in CO2 and making more difficult the absorption of this nutrient main plant. Therefore, installing a fan help getting stronger plants with thicker stem and a decreased risk of disease and pests.
As for renewal is solved by installing two extractors, one at the bottom of the enclosure to enter clean outdoor air and one on the top that is responsible for the outflow of hot and stale air. It is important that these fans also work in the dark period (light off) because plants also breathe when they perform photosynthesis.
To calculate the fan capacity I accepted this as a reasonable value to renew 30 times the volume of the cabinet per hour.
1.5 m cabinet. * 1.5 m wide. * 2.2 m high. long – & gt; volume = 1.5 * 1.5 * 2.2 = 4.95 m³
Volume cabinet 4.95 * 30 = 150 m³ / h (capacity of the extractor)
Multiplication by cuttings: consists in obtaining genetically identical plants from a mother plant, clones. These clones will be of the same quality, variety, and even sex are equally susceptible to the same type of disease as the mother plant. Cuttings were taken in the period of growth and with an approximate size of about 7.5cm. To separate them from the plant is to make a clean cut through the plant to heal as quickly as possible. These sprouts cut is made in the stem to 45 ° and the lower leaves are removed. It may be desirable to trim them to the rest of the sheet ends in order to reduce transpiration (loss of water). Finally, the stem is immersed in a solution of rooting hormones (eg. Clonex …) and placed in rock wool or peat into a hotbed. After 10 or 15 days keeping conditions optimal temperature and humidity (25 ° C and 80-85%) the cuttings have developed a good root system and will be ready for transplanting.
