I think I ask this question about every 6 months but the market is ever changing and I am looking for an earth shattering kind of difference. I have tried a lot of different brands that I use in addition to Liquid Orca and none really seem to add anything more than if I just use Orca. I do add a little Amino acid and Humic acid and kelp in the mix and that does make for a little bigger root ball a higher brix.
This grow I am using this but at $15 a res change I didnt see any difference. GreenEden EndoBoost Hydro Concentrated Soluble Mycorrhizal Fungi - Root Boost - 2oz. Endo Mycorrhizae Inoculant.
look at King Crab at ("Plant Success.com") creators of Great White, Orca, ect also one that is alway on the top list of _- House&Gardening - Root Excellator (many good reviews, liquid) also KLM by Dyna-Gro (liquid) sample packs of their hydro nutes' line (5) sample packs available. Have used all that mentioned with good results
I like their Orca in hydro and Great White in coco or soil but I dont get why they would have a 3rd brand to compete against the other 2. Crab King has a bigger variety of bacteria but a lower count. What does that mean?
