atalogue: Section 3: Nutrients And Additives

As with all hydroponic systems, it is only as good as the food that you use. Below are listed and illustrated the leaders in the nutrient market. It is our belief that some nutrient in some cases give better performance or pH stability than others. However personal preference and subjectivity rules the day. A lot of the time its like asking what’s better? Red or white wine? Bitter or larger? It depends apparently on what your eating with your drink! Well if you believe that then your believe anything. Hydroponics is the same if you find a nutrient you like and you believe it performs well then stick with it. If you are unhappy with your results then experiment with another make or a combination of makes and products, your got nothing to lose.

Nutrients are very important in hydroponics. They are the sole source of nutrition for your plants and you should always feed your plants with the best there is available. At Esoteric Hydroponics, we take our nutrients very seriously and can assure you that we only have on offer the best that there is available on the market today. Generally speaking, there are grow nutrients (for young plants and vegetative growth) and bloom nutrients (flowering and fruiting). Formulations are available for all of our nutrients. Also, we offer hard water and soft water formulations for many of our nutrients to suit the various water types around the UK and to ensure your growing success.

Do you have hard or soft water? You need to know the answer to this for best results with many of the nutrient formulations available on the market today. If you are unsure why not contact us for a precise answer to this question.
