Now remember that we said an Indica/Sativa cross would produce two different highs. We will explain what the photoperiod is in a moment. Ruderalis is considered sub-standard by most growers because it flowers according to age and does not flower according to the photoperiod. It does not produce large quantities of THC, nor does it flower like the other varieties. However ruderalis is a problematic plant. INDICA/SATIVA (This is a 50/50 cross between a Sativa and an Indica species)Īnd some other Ruderalis mixes. INDICA (This is a mostly Indica species with some Sativa) SATIVA (This is a mostly Sativa species with some Indica) Seed producers tend to only produce the following strain categories. Most hybrids do not last long on the market and are primarily found only among breeders who are experimenting with their plant’s genetics. They are classified in a different way that we will explain this in the strain format table below. These complete hybrids plants are mixed so much that they can not be classified at either Sativa or Indica.

Those 250 are usually very unstable crossbreed strains. Out of the 450 seed varieties we said that 200 where good. Each strain is either a pure species type (taking 2 plants of the same species and crossing them) or a crossbreed of two or more species (taking 2 plants from different species and crossing them). Out of the 450 seed varieties, 200 are worth looking at and out of the 200 varieties about 50 or so are outstanding. At the moment there are approximately 450 seed varieties of Cannabis on the market today.
