Optimum Bloom – Part A & B: Hydroponic Nutrient for Flowering and Fruiting

Optimize Your Harvest with Optimum Bloom

Optimum Bloom is an essential component of the twin-pack nutrient system for hydroponic cultivation. Designed for the flowering and fruiting stages of plant growth, Optimum Bloom is the key to unlocking a bountiful and vibrant harvest.

Key Features:

  • Bloom-Specific Formula: The nutrient composition in Optimum Bloom is fine-tuned for the flowering and fruiting stage. It features reduced nitrogen levels and increased phosphorous and potassium, vital for initiating and developing buds and flowers.
  • Pure and Potent Ingredients: Optimum Bloom is crafted from the highest quality, most soluble mineral salts, ensuring your plants receive the precise nutrition they require for spectacular flowering and fruiting.
  • Consistent Nutrient Availability: The inclusion of chelates in Optimum Bloom guarantees that essential micronutrients remain available to plants, even when pH levels fluctuate.

Ideal For: This formulation is especially effective in NFT, Flood and Drain, and recirculation hydroponic systems, and is perfect for mediums like perlite or clay.
