Weed Growing Yield and Quality

[Johnnywong]

I'm wondering if there's anyway to improve the weed growing yield and quality?

Genetics, lights, and nutrients.

I agree with rigman. But would add knowledge and experience.
A lot of new growers expect massive yields of top grade weed right off the bat. It takes a while to learn your craft.

I agree with both of the above.
Also, stop reading crazy promises from seed banks and grow kits manufacturers.. Get some realistic expectations.
