Hi, im getting ready to bring some iranian autos out doors. I started them outside but have been bringing them in at night. The place im moving them to has good soil, land is right next to corn fields. I plan on digging some nice holes and adding perlite to the dirt. Do you guys think I should add in some good store bought soil? Anything else I should throw in while mixing like some worm castings. This is my first grow, ive been researching as much as possible. Just want to do this right. Thanks for any advice on this.
