smoke24answered grow question 4 years ago I prefer pro-mix which is basically peat and perlite. I like it because it holds on to moisture better than coco and seems to have less ph variation. If you have pro-mix available or some other brand of peat and perlite I would give it a try, however thats just my opinion, there are plenty of others who favor coco over pro-mix. It's up to you, of course you could always do one plant in coco and one in pro-mix and see which you like better. Happy growing.
