We stock full ranges from UK brands such as HYDRoToPS, Plant Magic & Shogun Fertilisers alongside European brands including CANNA, DutchPro, Mills Nutrients and overseas brands like House & Garden, Green Planet, FloraMax and many more.

Why Use Plant Boosters?

Plant boosters and additives are feeds or fertilisers used to increase the yield of your plant. In order to create optimal conditions for growth, plants require certain nutrients. In nature, they are drawn in from the soil, but in a hydroponic system, plants need to get these nutrients elsewhere. So, plant boosters and additives are used to provide plants with the perfect balance of nutrients for growth.

What Nutrients Do Plants Need?

Plants rely on a minimum of 14 essential mineral elements to thrive nutritionally. These vital nutrients encompass:

  • Nitrogen (N)
  • Phosphorus (P)
  • Potassium (K)
  • Calcium (Ca)
  • Magnesium (Mg)
  • Sulphur (S)
  • Chlorine (Cl)
  • Boron (B)
  • Iron (Fe)
  • Manganese (Mn)
  • Copper (Cu)
  • Zinc (Zn)
  • Nickel (Ni)
  • Molybdenum (Mo)

Different plants require different quantities of each nutrient and using the correct amount will greatly assist in the growth of plants in any growing system.

The Benefits of Using Nutrients, Boosters and Additives

There are many benefits of using nutrients and additives in your hydroponic growth system. 

  • Maximise growth and yield - Your plants will flourish with all the essential nutrients they need
  • Optimise plant health - Additives can address specific needs like root development or disease resistance.
  • Enhance nutrient uptake - Your plants will more effectively absorb nutrients with advanced formulas.
  • Improve flowering or fruit development - Boost the productivity of your plants and stimulate fruit or flower production.
