Sativas and Indicas are very different, like night and day. They are tall, thin plants, with much narrower leaves and grow a lighter green in color. They grow very quickly and can reach heights of 20 feet in a single season. They originally come from Colombia, Mexico, Thailand and Southeast Asia. Once flowering has begun, they can take anywhere from 10 to 16 weeks to fully mature. Flavors range from earthy to sweet and fruity. The high of a Sativa is cerebral, up and energetic. Sativa's offer more of a "head buzz".

This type of high is the one most associated with hilarious fits of laughter, long discussions about nothing, enhanced audio and visual senses. You hear things in songs you've never heard before, see things in movies you've watched a dozen times but never noticed before.

The success of the eventual outcome will depend on your personal tastes and the conditions in which they are grown. Tests of THC percentages of most strains is rare and we are not really sure what the numbers mean when disclosed.

THC is found in the resin glands that form on the plant during the maturation process. These glands act as a shield to protect the seed from the searing heat of the sun. From our experience this is needed more in a hot, dry atmosphere, than a hot humid one.

To maximize resin production drop the humidity in the room for the flowering stage, the lower the better. But no matter how much resin you induce on an indica it's still not going to give you the stone of a sativa, so it does have a lot to do with your personal tastes and expectations.

All of the yields for the strains are approximate and depends a lot on how they are grown and the quality of the environment. Indoor lights don't penetrate down very far so it is better to grow a larger number of smaller plants to achieve the highest yield of top quality bud. Maximum yields indoors are coming from indicas and mostly indica hybrids, while the more sativa in the mix, the lower the yields tend to be.

The yield indoors is really limited only by the amount of light available, not the strain you choose. Given that it is a good growing environment, you can expect the yield to be about the same from any strain in relationship to its indica/sativa content. It is up to your designated marijuana grower to maximize the plant's potential in his space.

The most desirable strains for medical use are ones that have been genetically developed by experts to have an extremely low CBN concentration while maintaining an available range of THC concentrates.

Indica generally more physical than cerebral (however, the relief of physical symptoms can have a positive psychological effect)

The efficacy of cannabis is directly related to strain selection. Care should be taken when selecting strains that will benefit you. Potency and dosage vary with different strains, conditions and individuals. The idea is to consume as little as possible of the most appropiately potent strains available in order to reduce costs and potential side effects.

Most cannabis seeds and medicine available today are from hybrids - crosses of Sativa and Indica varieties. This allows cultivators to enjoy and select for various desired characteristics of growth, appearance and effect.

The genetics and hence the effects of one lineage will usually be dominant. For example: Indica-dominant crosses are for pain relief, with the sativa component helping with energy and activity levels.

Sativa-dominant crosses are good for stimulating appetite, with the indica component helping to reduce body pain and increase relaxation.
