  Do you know what type of seeds you want?

Ruderalis, Indica and Sativa are the three different types of cannabis, believed to have come from Central Asia. Nowadays most cannabis is a hybrid of Indica and Sativa with some strains more genetically dominant in one or the other.

Sativa grows into a tall, thin plant with an abundance of branches, flowering between ten and fourteen weeks and providing a high yield. Because of its high T.H.C levels it is good for helping with depression, improve concentration and also for the relief of nausea and increase appetite. This makes it extremely good for helping to treat people who are undergoing chemotherapathy or suffering with AIDS. Sativa is known as the "Day" high as it acts more like a stimulant. 

Indica strains however, grow into short, compact plants, flowering between eight and twelve weeks and also producing high yields. Due to their higher levels of C.B.D Indica strains produce a more physical hit, helping to relax the body. This makes them medically very helpful with acute pain, insomnia, migraines and can also help to reduce seizures. Indica is known as the "Night" high as it acts like a relaxant.

Ruderalis, although being a rather small weed-like strain that is low in T.H.C, it is often used for crossbreeding. Thus producing plants that, regardless of the photocycle, will flower after a short time producing hybrid, autoflowering plants.
