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

Drive Peak Flowering and Maximum Yield with FoxFarm Cultivation Nation Bloom — Step 3 of the 3-Part Feeding Program

FoxFarm® Cultivation Nation™ Bloom 0-5-4 is the finish-line powerhouse in the Cultivation Nation 3-Part liquid feeding system. Formulated to trigger and sustain abundant flower production from first bud set through final harvest, Bloom delivers the phosphorus and potassium your plants need to build dense, resin-rich, high-quality yields.

Key Features & Benefits

• 0-5-4 NPK Ratio: Zero nitrogen with elevated phosphorus and potassium — the precise flowering-stage ratio to redirect plant energy from vegetative growth to bud development.
• Step 3 of the Cultivation Nation System: Completes the 3-part feeding program alongside Cultivation Nation Grow (Step 1) and Cultivation Nation Micro (Step 2) for full-cycle liquid nutrition.
• Triggers Flower Initiation: Introduce Bloom at the first sign of bud development to maximize early flower set and bud site density.
• Sustained Through Harvest: Continue through the full flowering period and use as the primary base nutrient until the final flush phase before harvest.
• Liquid Concentrate: Fully soluble, fast-acting, and easy to mix into any nutrient reservoir or irrigation system without sediment or clogging.

Who Should Use This

Cultivation Nation Bloom is designed for hydroponic cultivators, indoor growers, and greenhouse operators who are running the complete Cultivation Nation 3-Part system and need a precision flowering nutrient to carry their crop from bud initiation to a full, heavy harvest. It is especially effective in high-intensity lighting environments where phosphorus and potassium demands during flowering are elevated.

Compatibility

Cultivation Nation Bloom is compatible with all growing media — including soil, soilless mixes, coco coir, rockwool, and hydroton — and performs well in all hydroponic delivery systems including DWC, NFT, drip, ebb & flow, and aeroponics. Pair with Cultivation Nation Micro (Step 2) throughout the flowering stage and use FoxFarm Cultivation Nation pH Down to keep solution pH in the optimal range (5.5–6.5 for hydro, 6.0–7.0 for soil).

Frequently Asked Questions

When should I switch from Grow (Step 1) to Bloom (Step 3)?

Begin introducing Cultivation Nation Bloom at the first visual signs of flowering — typically when the plant shifts from producing vegetative shoots to forming flower sites. Continue Bloom through the entire flowering period until your final pre-harvest flush.

Do I continue using Cultivation Nation Micro (Step 2) with Bloom?

Yes. Micro (Step 2) is designed to be used alongside Bloom (Step 3) throughout the flowering stage to ensure continuous micronutrient coverage. Refer to the FoxFarm Cultivation Nation feed chart for recommended ratios at each stage.

What happens if I use Bloom too early in the vegetative stage?

Using a 0-5-4 bloom formula during active vegetative growth can restrict leaf and stem expansion due to the absence of nitrogen. Always follow the recommended transition timing from the FoxFarm feed chart for best results.

Can I use Cultivation Nation Bloom as a standalone bloom booster?

While it can supplement other programs, Cultivation Nation Bloom is formulated to perform as part of the complete 3-part system. For best results, use in conjunction with Grow (Step 1) and Micro (Step 2) as directed.

Is a pre-harvest flush recommended after using the Cultivation Nation line?

Yes. FoxFarm recommends flushing with plain, pH-adjusted water during the final 1–2 weeks before harvest when using any synthetic feeding program, including the Cultivation Nation line. This helps clear residual salts from the root zone and media.
