mhpgardener | Final Results - Hydroponic Fertilizer Experiment @mhpgardener | Uploaded March 2013 | Updated October 2024, 1 week ago.
I've been working on an experiment comparing water soluble fertilizers for hydroponic growing. Here is how it began: youtu.be/oeLd2SP0c6U The final results are in. When it comes to hydroponics, Miracle Grow is not recommended because it has a form of nitrogen that is best suited for use in the soil. It does poorly in a hydro application. The 4-18-38 hydroponic fertilizer that I have been using for awhile now absolutely kicks butt. My recommendation for anyone wanting to grow hydroponic vegetables is this: find a true hydroponic fertilizer to use, and leave the Miracle Grow products for the soil. The results speak for themselves.
