"I have been growing hydroponic basil for the past four years. The first three years, I struggled to grow the "perfect" crop. The basil was continuously experiencing nutritional disorders. Last year American Hydroponics came to my rescue, supplying our company with a custom designed nutrient formula. I am now growing "perfect" crops and have since then doubled the size of my business. Thanks you guys."

All of our 2-part crop-specific nutrients have subtle adjustments in their formulations: tailor-made for specific crops and are designed to work with phosphoric acid as a pH adjustor which is why the phosphorous percentage is low in all the formulations.

Evolution Solution comes in an 8kg (18 lb), 20kg (44 lb), and 60kg (132 lb) box or as *trace element mixes where the grower supplies his/her own bulk ingredients to our specifications. The grower saves lots of money on shipping this way. All nutrients come with detailed instructions for mixing and a guaranteed analysis.

For maximium crop performance we recommend that you obtain a source water analysis before we design a nutrient specific to your source water and plant in cultivation. We do this for $75. For another $125 we design a custom nutrient formula for your operation and send it to you pre-mixed for the costs below. After we dial in your formula, you obtain a tissue analysis after a month and send it to us. We can then further tweak your formula in anticipation of seasonal fluctuations.
