I am going to be growing outdoors for the first time and am wondering about the soil. Currently I am planning on tilling and a product called Nutri-Rich 4-3-3 pellets into the soil and hopefully that is all I will need to add. Its an organic pelletized fert. I am growing some of Dr. Greenthumbs Iranian autoflower, which have a 90 day complete cycle. My question is will this work?
