Description
Hydrotops Bioponic Hydro Bloom for Soft Water is a professional two-part hydroponic flowering nutrient specifically formulated for use with soft water sources — municipal tap water or reverse osmosis water with low calcium and magnesium content. We have been recommending Hydrotops Bioponic nutrients to UK hydroponic growers since 2017 as a reliable, organically enhanced nutrient system that bridges the gap between synthetic precision feeding and biological growing approaches.
Why Soft and Hard Water Formulations Are Different
The mineral profile of your source water directly affects the balance of nutrients available to your plants when mixed with a standard nutrient concentrate. Hard water already contains significant quantities of calcium and magnesium carbonate — adding a nutrient formulated for soft water to hard water results in excessive calcium levels and a nutrient imbalance. The Soft Water formulation accounts for the low baseline mineral content of soft water, delivering a complete mineral profile including the additional calcium and magnesium that soft water cannot supply.
Using the correct formulation for your water source is not optional for optimal results — it is fundamental to achieving a balanced nutrient solution that your plants can actually use efficiently. Hydrotops’ separate soft and hard water formulations eliminate the guesswork and allow you to dial in a correct mineral profile from the first grow.
Bioponic Technology and Feeding Programme
The Bioponic range uses a combination of mineral nutrients and organic plant extracts — including seaweed, amino acids and humic substances — that support both direct plant nutrition and the biological activity in coco and organic media that improves nutrient cycling and availability. Apply Parts A and B in equal ratio at the manufacturer’s recommended rates, adjusting final EC to suit your crop stage.
Use from the start of the flowering stage through to one week before flush. Pairs with Hydrotops Floral Boost, Top Heavy Crop and Triple F for a complete bloom programme. Finish with Hydrotops Bioponic Flush for Soft Water for a matched end-of-cycle flushing protocol.
