Factors for killer weed

What’s the most important factor with growing killer weed? Would it be soil, temperature, nutrients, or something else?
Bud Lover,

The most important factor that affects the quality of the weed you are growing is the plant’s genetics. No matter how well a plant is grown, it can only reach its potential. The cheapest way to improve your garden is to find better varieties. Then grow a healthy plant under plenty of light and it will perform for you.
