So I've been looking around, reading and searching on what the best soil mixture for an outdoor grower would use and I can't seem to find any specific medium.

For a urbanized area, I have yet to find any soil that would be completely acceptable for a growing spot. I'm shying away from using 5 different pot sizes for transplanting. I'm looking to maybe buy 3 ( 3inch, 6 inch, maybe one more larger) and then make a final transplant to ground outdoors. I've read a few ppl are using bat guano, horse manor, and blood meal.

SO my questions are what type of nutrients or soil additives are best for an outdoor grow area? And if the three above are good sources of nutrients, should they be used separately or can they be combined? are some better for veg or flowering?

any feedback will be helpful. If it helps I'm hoping to get a couple ak48s and haze X skunk #1s outdoors asap. 5 in all. thanks
