Your attic, cellar or spare bedroom could quite easily provide you with your own professional sinsemilla growing room. When growing inside, you control all the conditions yourself but, of course, it also requires some know-how. This introduction is intended to give you an impression of what is entailed if you want to grow weed yourself; it's a summary of the entire growing process. Using a little knowledge and your green fingers it is easier than you think.

We advise you to purchase a copy of Organic Earth's book ‘Sinsemilla, Productive Domestic Cultivation On Ecological Basis’. This is the growers' manual that guides you in a clear and uncomplicated way through the various steps necessary for setting up a professional growing room.

indoor growing
A plant's environment is determined by three factors:
1) air
2) light
3) nutrition

Once a suitable room has been selected, thoroughly cleaned and made insect free, ventilation becomes your first concern. It is important that fresh air can enter easily and that the stale air is removed immediately. In this way you regulate both the CO2 content and humidity of the air, two vital factors in the plant's metabolism and therefore indispensable to its growth.

Stale air is warm, consequently the air outlet can best be located high in the wall. The air inlet is then located low in the opposite wall to ensure that the fresh air is quickly replenished throughout the room. A centrifugal extraction ventilator will ensure that the air in the room can be changed quickly and making the inlet twice as big as the outlet will prevent any possible vacuum-like circumstances occurring and guarantee fast ventilation.

It is easy to connect the ventilator to a switched thermostat to allow it to respond efficiently to fluctuations in the air's temperature and humidity. It is also a good idea to hang a hygrometer in the growing room.

Sodium lamps are ideal for growing plants inside because of their corona discharge
and you can choose between 400 or 600-watt systems.
The difference between these two lies in the weight of the ballast and the intensity of the light.
To maintain maximum light output, it is best to change the bulbs once a year.
this sort of equipment will increase your electricity bill.

- never make illegal electrical connections - use an earthed electrical supply - do not connect to the same mains ring as the kitchen

Soil and fertilisers
Once you have equipped your growing room as far as ventilation, electricity supply, tables and lamps are concerned, you can proceed to the third stage: getting soil and clones or seeds and actually beginning to grow. Our company sells Complete Mix: a ready-to-start enriched soil mixture, which contains all the necessary nutrients in the correct proportions. This special mix has been pre-treated so that the plants can extract their nutrition easily..

It goes without saying that you can also find a wide range of organic fertilisers in our shop. The fertilisers and growing mediums that are suitable for the cultivation of edible plants are assessed on their pH value and the presence of such elements as nitrogen, phosphorous, potassium and magnesium. In order to neutralise the soil and bring it to the required pH (pH 6 to 7) chalk is often added to the mix.

Nitrogen is important for plant growth. Phosphorous enhances bud growth during flowering. Potassium gives the plant strength, encourages root systems and increases resistance to disease. Magnesium is an important trace element for the plant's metabolism, which promotes the absorption of light and nutriments and thus helps the formation of new plant cells.More comprehensive information can be found in our book ‘Sinsemilla’.

The Growing room
Fill up all cracks and holes! No matter what, it is essential to ensure that the flowering room itself is light tight. The number of hours of darkness are of crucial importance to marijuana. Short nights of six hours make the plants grow, whereas long, twelve-hour nights, cause the plants to flower. This response mechanism is known as the photoperiod. For best results it is necessary to ensure that the walls are either white or are covered with a light reflective material.

Important!

• the growingroom must be lighttight
• always clean
• avoid bringing any plant or animal matter into your growing environment. Consider wearing a special set of clothes and a hairnet when entering any growing room.
• it is best to keep pets outside these areas
• smoking is forbidden the plants' air would become polluted.

Culture & Harvest
Plant cuttings or seeds in peat pots standing in a soil/ perlite bed on a ‘tray’. It is advisable to use demineralised, or some other type of filtered water, for keeping the soil moist but not too wet. After about two weeks, the small plants will have grown roots and can be transplanted into bigger pots filled with an enriched soil mixture. The following week, give the plants 18 hours of light per day. An automatic timer to switch the lamps on and off is practically indispensable.

The following week, the plants will be induced to flower by converting to a twelve-hour light/dark cycle. This cycle of 12 hours absolute darkness and 12 hours light is continued for between 8 and 9 weeks, by which time the plants should be ready for harvest. During harvest the large leaves are removed and the plant is cut down.

During harvest the large leaves are removed and the plant is cut down.
Let the sinsemilla dry by hanging it in a ventilated, darkened room at 18° C for a minimum of two weeks. After this, cut off the buds and clean them: leaves, branches and twigs are unsmokeable. The final result should be carefully packed in three layers of plastic with a ‘"100% oxygen barrier"’ specification. If you want to keep the sinsemilla as fresh as possible for a longer period of time, then vacuum-pack it. Never pack sinsemilla when it is still wet, because of the danger of mould!
