what is the best way to grow autoflowers?

Fruitgrower and Mrcannab1sir are correct, im going to also add that there are many great growers on youtube that can give you some good information, two of my favorites are Bill Ward, and Mr. cannuck. Back when I first started growing, I spent probably 80 hours just researching, learning, watching, before I ever dropped my first seed. I recommend you do the same, you will be much better off in the long run. Happy growing.

Agree with FG, just don't overdo it, if it's your first time just grow 1 naturally, no LST or topping etc, just watch and see how it grows

First advice to give. Do some research, so many great articles on the Web and books you can buy telling you everything you need to know. Make sure you have a nice aerated soil, good light source, good seed genetics, good airflow and at least the basic nutrients
