Peace Tia....Thick as in your plants or your pants?
and i mean that in a Positive way
...i am not a Genious on Growing and have small grow...I am N2 Quality over Quantity, but will try to answer you as best i can...They are they two diffetrent types of plants Indica & Sativa that are Grown..
Indica -- Indica is a great plant to grow indoors as well as outdoors due to its low lighting requirements and tight internode spacing, also offering resistance to fungus and pests, early maturation tendencies, and dense flower production. Indica's come from colder climates exhibiting the traits described above by acclimating to the environment from whence they came. Their stout stature and extremely wide leaflets make them easy to identify. An Indica generally produces a hard hitting, tiresome, sedative stone, and will take around 45 to 60 days to finish flowering.
Indica: Shorter, THICKER, Body High.....
Sativa -- Sativa is a hard plant to grow indoors due to high lighting requirements, tall stature, and late flowering traits. Sativas come from equatorial regions, thus the neccesity for high ammounts of lighting and a warmer tropic-subtropic climate. You can identify a Sativa by its long, slender, finger-like leaves. A Sativa will typically produce a euphoric, energetic, cerebral high. Despite the Sativa's climatic limitations, they are truly a reward to obtain, grow, and smoke. A pure Sativa will take 2 to 4 months to finish flowering.
Sativa: Grows Taller, Thinner, Heady or active high....Both make me create things
