FoxFarm® Cultivation Nation™ Bloom 0-5-4 — 1 gal (Step 3)

Drive Flowering Development Through Harvest, Step 3 of a 3-Part Feeding Program

FoxFarm Cultivation Nation Bloom 0-5-4 is Step 3 of the Cultivation Nation 3-part liquid feeding system, a zero-nitrogen, phosphorus- and potassium-rich formula that drives flowering development through harvest. It is designed to work alongside Grow (Step 1) and Micro (Step 2) for complete, season-long nutrition delivered as a fast-mixing liquid concentrate.

Maintaining solution pH between 5.5-6.5 for hydroponic systems and 6.0-7.0 for soil-based growing keeps every step of the Cultivation Nation system fully available to the plant, and FoxFarm Cultivation Nation pH Down is formulated to dial solution pH into that range when it drifts.

Key Features & Benefits

• 0-5-4 NPK Ratio: A zero-nitrogen, phosphorus- and potassium-rich formula that drives flowering development through harvest.
• Step 3 of the Cultivation Nation System: Formulated to work with Grow (Step 1) and Micro (Step 2) for full-cycle liquid nutrition.
• Redirects Plant Energy Toward Flower Development: With zero nitrogen and elevated phosphorus and potassium, Bloom shifts the plant's nutrient balance away from vegetative expansion and toward flower-site development.
• Liquid Concentrate: Fully soluble and fast-mixing into any nutrient reservoir or irrigation line without sediment.
• Broad Growing System Compatibility: Suitable for soil, coco coir, rockwool, and hydroponic delivery methods including DWC, NFT, drip, and ebb & flow.

Who Should Use This

Cultivators in high-intensity lighting environments where phosphorus and potassium demand rises sharply during flowering are the clearest fit for Bloom as the finishing step of the 3-part sequence.

Frequently Asked Questions

When should I switch from Grow to Bloom?

Introduce Bloom at the first visible signs of flowering, when the plant shifts from producing vegetative shoots to forming flower sites. Continue Bloom through the full flowering period until a final pre-harvest flush.

What is the correct mixing order for the 3-part system?

Add each concentrate to water separately in this order: Grow first, then Micro, then Bloom, stirring thoroughly after each addition. Never combine the concentrates directly without diluting each one in water first.

What happens if Bloom is used too early, during active vegetative growth?

Applying a zero-nitrogen formula like Bloom during active vegetative growth can restrict leaf and stem expansion, since nitrogen is what drives that stage. Follow the recommended transition timing rather than introducing Bloom ahead of the first flowering signs.

What pH range should I maintain when using the Cultivation Nation system?

FoxFarm recommends a pH of 5.5-6.5 for hydroponic systems and 6.0-7.0 for soil-based growing across all three steps of the system. Cultivation Nation pH Down is formulated to bring solution pH into that range when needed.
