Latitude and attitude :)

Indica grows further North
Gives relaxing and laugh inducing effects.

Sativa grows closer to the equator
Effects are uplifting and cerebral.

Speak for your own hemisphere mate

As everyone else said in terms of the physical differences of the plans and the effects.
I can’t take sativa anymore. I use. to when I was younger. Just a small amount of sativa sends my brain on a awful spiral as my mind runs fast anyway. Shame as I used to love Thai weed.
I just smoke Indica now. Relaxes mind and body without the circular thoughts / paranoia.
Seems that anything from the Afghan/Indian areas is perfect. Smoking some Hindu Kush Weed and Afghan Black hash atm.

My man

Indica = In da couch

Sativa = Sat up talkative

Indica is short flowering, short and sleepy, sativas are opposite generally

I read somewhere that a strain is considered to be indica when it has 5% or more of the terpene myrcene which causes the sedated couch lock effect.

Interesting

How it grows

The distinction in effects can be altered when using a vape - indica at a low temp will give "sativa" effects and a sativa at a high temp will give "indica" effects

thats crazy, how

sativa is uplifting indica is more to help sleep or relax

Sativa tends to grow tall and skinny with pointy leafs. Usually take longer to flower. Indica are shorter bushier, chunkier leafs/flowers faster flowering

asapcocky cool username lol
new addition to the asap crew?

also there is a notable difference in the way the plant grows
indica tends to grow short stocky and bushy with wider fan leaves

whereas sativa tends to grow tall and has thinner fan leaves

and as stated in the comments already, difference in types of high

cheers, THB
