Evaluation Criteria:
Quality of Ingredients
The ingredients used to produce hydroponic nutrients such as phosphorus, potassium and amino acids are important to the performance of the product. In addition, the type of ingredients used, how those ingredients can affect the performance and the overall quality of that type of ingredient is reviewed when comparing them to other competing products in the same market.
Features
The features of a product need to provide benefits to the consumer. Features of nutrient products that are reviewed provide a distinctive characteristic that sets it apart from similar items. This includes but is not limited to growth improvement, safety, increased yield and natural ingredients.
Yield
It is important how effective nutrient products are at improving the yield of the growing operation when compared to the cost of the nutrients and the amount required to produce results. Nutrient products that produce more at a fair cost are recommended over products that might underperform or require more volume to yield results.
Efficiency
Efficiency is important to review for nutrients because this product has the capability of producing a desired result. When something is deemed efficient, it has an intended or expected outcome, such as increased yield without waste. Nutrient products that produce more results at a fair cost over products that might underperform should be considered.
Value
While value is something that can be difficult to measure, it is something that can be compared between similar products. During consideration of different nutrient products, the value the average buyer will see compared to how much they have financially invested into the product is reviewed.
