Most phenotypes are rich in CBD (cannabidiol) with a low THC (tetrahydrocannabinol) content allowing patients to retain the medicinal cannabis benefits of the CBD without the usually overwhelming effects of high-THC. Otto #1 produces three gross chemotypes and each one expresses varying ratios of CBD:THC - some even reaching levels as high as 27:1. Otto #1 grows tall with an open foliage pattern; sativa-type characteristics and will produce light sativa-like buds. Mould should not be a problem as foliage and buds are not too dense. Although this strain might grow like a sativa the breeder is keen to emphasize that the chemotype is outside of the range that would be covered by normal Sativa/Indica descriptions. The CBD content of these cannabis seeds make them great for medicinal marijuana users.
