INDOOR strains are generally only intended for indoor growing with artificial light. The optimal light conditions available indoors will allow these strains to reach their full potential. It is possible to grow these strains outdoors if you live in a warm, sunny climate, such as the Southern hemisphere, equatorial regions, the tropics and subtropics.

INDOOR / GREENHOUSE

These strains are suitable for the widest range of growing conditions. They may be grown indoors with artificial lights just as successfully as the regular Indoor strains. In the Northern European spring and summer, they may be grown in a greenhouse with just the power of the sun. In Southern Europe and beyond they may also be grown outdoors with great success.

OUTDOOR

Ourdoor strains are those that may be grown outside in spring/summer, even in Northern Europe. Of course, these varieties will also flourish elsewhere, but their hardiness and early-flowering tendencies will allow them to ripen even in a short, cool summer.
