Growing indoor strains outside

• Indoor seed strains are most suited to growing indoors with artificial light.
• High Intensity Discharge (hid) lamps are the most efficient source of artificial light.
• While other lights can be used in the growing stage, plants should be flowered with at least one 400-watt High Pressure Sodium (hps) lamp.This is the minimum lighting required for indoor plants to reach their full potential.
• Optimal lighting for indoor cultivation is one 400w hps per square metre OR one 600w hps per 2 m2.
• In warm and sunny climates 45°N and below indoor seed strains can also be grown outdoors.

Growing indoor/Greenhouse strains outside

• Indoor/Greenhouse seed strains can be grown indoors with lights in the same way as the indoor strains.
• Indoor/Greenhouse seed strains can also be cultivated (and may become much larger) in a greenhouse, growing and flowering with the light of the sun during spring and summer. Greenhouse growing is possible in almost any part of the world, in some locations as far north as 65°N, provided that the greenhouse gets plenty of direct sunlight.
• In warm and sunny climates 50°N and below Indoor/Green-house seed strains can also be grown outdoors without the aid of a greenhouse.

Growing outdoor strains

• Outdoor seed strains can be grown outside in almost any part of the world - in some locations as far north as 65°N.
• Please note: although many parts of the world have a mild or warm winter, outdoor growing is usually only possible in spring and summer. This is because most cannabis relies on a changing photoperiod (hours of light per day) to flower, mature and ripen. Near the equator, where the day stays around 12 hours in length all year long, outdoor growing is possible at any time except the wet season. Outdoor growers in the tropics are advised to choose Sativa strains, which are native to the equatorial regions and can perform superbly in a constant 12-hour photoperiod.
