Fox farm and General hydroponics both make one of the easiest sets of nutrients to grow plants from seed to harvest. The problem is both of them have flaws in the NPK ratios which is a ratio that establishes the percentage of Nitrogen, Phosphorous and potassium that are in the bottle. They are primary elements that a plant needs in order to grow and secondary elements, such as calcium and magnesium need to be added to the Fox farm trio, but not as much in the general hydroponic trio. Both of the trios have flaws so to say one of them is clearly better would be a mistake. Ultimately, the best thing I would do is to just choose Flora Micro and Flora Bloom and use the money saved to buy Calmag or TPS Silica. We have a ton of proven grows on our discord community and although both of the trios have been proven out, our crowd sourced data shows that the General Hydroponics trio has proven itself over with more consistent harvests.

Products we recommend:

General Hydroponics Flora Micro:
General Hydroponics Flora Bloom:
You can use F Micro and F Bloom exclusively for a whole grow!!!
TPS Silica (Strengthens stems and lets plants deal with extreme temps)
TPS Signal (Signals bloom, a K booster with Magnesium and Sulfur)

  1. Do you happen to have any test tutorials for growing an auto flower in happy frog? Whilst using the fox farms trio and cal mag?


      The soil was happy frog using Fox Farms though, I would imagine the General hydroponics would be better in terms of P values, but the structure of the plant would probably be the same, small and poor yields.

    2. I use 2 cubic feet of Happy Frog mixed with 2 bricks of coco coir and a small bag of perlite. I use GH Flora Trio (not fox farm) at 1/2 manufacture’s recommended amounts. At the beginning of flower and maybe 1 or 2 times during I hit it with a little Recharge. In a 2x2x4 tent with a 200w Q-Board in 5 gal fabric pots I consistently get 4-5 oz per grow (1 auto plant)
