Oh, and just incase he/she doesnt know the difference between Sativa and Indica heres some of what i know...

Well..

Sativa- Usually has long thin leaves. Grows kind of tall in the wild, then again so does all weed, but sativa is known for its tallness...Sativa highs tend to be more savy and very active in the body..

Indica- Usually has wider leaves. Grows generally shorter and stockier than Sativa in the wild. Indica highs tend to be more or less centered on the brain and usually cause a more intense stonish high...

Now of course this is just a general idea and can be different in many different conditions. Plus a lot of strains contain much of both strains(Indica&Sativa) and the highs can be somewhat interesting to explore because each strain has its own distinct taste and high...

Your best bet is to not go by how much a plant can yield because it doesnt matter how much the plant yields, its more or less up to your growing conditions. Now if you find a strain that yields high and you think you may like it, try to get some info on how its grown the best to get the most of its yield by matching those conditions with yours..Good luck bro, happy harvest!
