Dutchfest Bloom A+B | Professional Flowering Nutrient for Hydroponic Systems

The flowering phase is where yield is won or lost. The nutritional requirements shift dramatically from vegetative growth — phosphorus and potassium become the primary drivers, calcium demand stays high, and the trace element profile needs to support the metabolic demands of flower initiation, development, and final ripening simultaneously. Dutchfest Bloom A+B delivers exactly this, in a formulation that has been trusted by Australian hydroponic growers for over two decades.

Available as a standalone A+B set for growers who want to manage their Grow and Bloom formulas independently, or who need to restock just the flowering formula without purchasing the full system again.

What Dutchfest Bloom Delivers

The elevated phosphorus and potassium ratios in Dutchfest Bloom drive aggressive flower initiation from the moment plants flip, then support bud density, mass accumulation, and resin production through to final ripening. The micronutrient profile is dialled in to maintain peak plant metabolism through the high-demand mid and late flowering phases when deficiency pressure is highest.

One of the most consistent complaints about high-performance flowering nutrients is tip burn and nutrient lockout at elevated EC levels. Dutchfest Bloom uses highly refined mineral salts that allow growers to push EC higher during peak flower development without the burnout issues common in lower-quality bloom formulas. Clean mineral sources also mean clear reservoirs and unclogged irrigation lines throughout the cycle.

The terpene and essential oil profile at harvest is supported by the trace element ratios in Dutchfest Bloom. Australian growers producing premium herbs, aromatic crops, and high-value flowering plants consistently report improved aroma intensity and flavour complexity when switching to Dutchfest from generic bloom formulas.

How to Use Dutchfest Bloom

Always add Part A to your reservoir first and circulate thoroughly before adding Part B. Never combine the concentrates directly. Add Part B after Part A has mixed, stir, then check EC and pH before feeding. Target pH range is 5.5 to 6.2 for optimal nutrient uptake in hydroponic systems.

Introduce Dutchfest Bloom at the start of the flowering phase when light schedule changes or natural flowering triggers signal the transition. EC can be progressively increased through mid-flower and reduced again in the final one to two weeks before harvest. Many growers finish with a flush using TA FlashClean to clear residual salts before harvest.

Buying Grow and Bloom Separately

Dutchfest Grow and Bloom are available individually for growers who run through one formula faster than the other, or who are managing plants at different stages simultaneously and want to restock a single component.

If you are setting up the full Dutchfest program for the first time, the Dutchfest Grow and Bloom twin pack provides both formulas together at a better per-litre rate. For precise nutrient management through flower, the Bluelab Combo Meter gives you pH, EC, and temperature in one reading.
