HARVEST Superpowered Organic potting soil?

I'm getting ready to start a new grow, and I'm going Organic My question is.......Has anyone used HARVEST Superpowered Organic Potting Soil? If so, what were your results? Should I add perlite, vermiculite, coco or anything?

i make my own "superpowered organic potting soil." on the cheap. peat/perlite/poop.......amend from there. blood, bone, guano, dolomite, humic acid, azomite, etc. once you have the amendments on hand, its nothing to whip up a batch of soil.

if you buy that.........test it for ph. add perlite. don't use it for seedlings. imo

Thanx for the feedback!I'm not so sure about mixing my own soil, but I'll give it a try....I'll try it out on a tomato plant clone for about 2 weeks just to see how good I mix it up. Thanx again, and Happy Growing!!

did your dirt end up working? I ended up buying some at the store. 5 bucks a bag.

and I also had a question is the harvest superpowered soil have a npk ratio of .10-.5-.5 or 10-5-5?
