When HydroTops designing the bioponic nutrient range back in 1998, the principal aim was to combine organic horticultural chemistry with the spirit and ethos of the organic grower, drawing upon in-depth knowledge of hydroponic growing and nutrients. Hydrotops was the first UK based nutrient manufacturer, and whilst Hydrotops products have evolved over the last 30+ years aims to remained the same; to produce high performance bio-organic nutrients that deliver consistent outstanding results for both hydroponic, coco and soil growers.

Hydrotops is proud to have introduced many ground breaking ideas and concepts to the hydroponic world. One such example is our legendary Triple F (Fully Formed Flowers). Introduced to the world in 2002 it was the first fruit and flower enhancer to increase yields by up to 40% whilst remaining 100% organic. Triple F continues to prove itself time after time as the finest natural flowering enhancer available to date. Its introduction to the market over 10 years ago prompted a number of flower boosting products to emerge from other manufacturers. Sadly many of these products have evolved from using plant growth regulator (PGR) chemicals to achieve their results. Whilst many of these products are successful at producing additional flowers and increasing yields, we believe nature offers the best solution every time.

HydroTops is always actively researching and developing the products and we are excited to announce At Slims Place some new additions to our range. For example the Next Generation range of Hydrotops nutrients, plus Top Heavy Crop (THC) - a formidable new growth and flowering enhancer. Along with Top Heavy Crop, Hydrotops Solo nutrients in January 2013, a simple single part nutrient for hydroponic and soil growing. Easy to use with truly professional results in a single bottle, again another first for HydroTops.

HydroTops have been producing custom nutrient formulations for UK growers since 90's and continue to do so to this day. Over the last 30+ years HydroTops have analysed thousands of water samples from all areas of the UK and the data base of water quality second to none. HydroTops is very proactive in the maintenance and expansion of the water quality data base, constantly re-analysing water samples from growers and HydroTops distributors, free of charge. It helps Hydrotops to maintain the excellent quality of service growers throughout the country have come to expect. This ensures Hydrotops products are the most effective and productive nutrients available in the UK today.
