Used Roots Coco soilless mix for the last grow. Very happy with it. Amended the soil with EWC, shrimp compost, and turface (I think it's much better than perlite and doubt I'll ever go back to perlite now). Chose coco to get away from peat based mixes. Used the full Roots Organic line minus the Orgenism, and I also used their Amino Aide. The company said that anyone wanting to boost their yields from the organic line should try introducing the Amino Aide and Big Swell to the grow. I was happy with the yield from the organics+Amino Aide, but I may try Big Swell in the future. Also using
Hygrozyme,
Dyna-Gro Protekt,
Great White, and
Fox Farm's Kangaroots. And I used the Roots fabric pots. Never used
Smart Pots so I can't compare directly, but the Roots bags are definitely awesome.
So I used those nutes and soil/amendments to grow out a couple of Sannie's strains. Great results, especially since this was my first run with these nutes. The biggest thing I noticed about the grow was how easy it was compared to most of the grows I've done in the past. The organics are just so simple. I had no problems with bugs.
I've used many nutes and various mediums over the years. Pro-Mix is great. Fox Farms was great when I used to use it. Roots is also great. I won't necessarily say it's better, but it's great stuff that you most likely won't be disappointed with. It's affordable, easy to use, and grows dank.
