Above the sea?

Hello,

I am looking on advices on cultivating plants over 1500 meters above the sea. I read in some books that weed grows better if is higher than 1500 meters. I have a mountain near me and I am planning to set a plantation. Is really true that the weed is better or no?

Thank you in advance

I don't see why it would be....Where did you hear this?

The higher the elevation , the more UV exposure , which is said to help potency
