Not commenting at all about the product, I have absolutely no experience with it at all. I will say that I will never ever come home with a soil, amendment, or anything that either Wal-mart or Lowes keep in their outdoor garden center ever again.
Each store provided me with a catastrophically unmanageable fungus gnat infestation that wiped out my grow both times. Literally didn't see one thing while I poured the soil into the pots. Two days after watering, they exploded out of everything. I tossed the new clones, the flowering plants that had just been transplanted and bug bombed the entire house and started over from seed both times. I think they're selling bags of pure fungus gnat eggs that are dormant until watering for shits and giggles.
I'm more than happy to spend $5-10 more per bag for what they sell at the hydroponic gardening store where they would have a very bad reputation if they let that kind of crap happen to their product. If they did that to one of the growers getting 5 pallets of soil for their grow houses, it's not likely they'd stay in business very long.
