SUPERthrive Bloom Plant Nutrients 3-12-6 | 32oz - (Case of 12)

Phosphorus-Forward Bloom Formula for Flowering Plants, 32 oz

Plants that carry a vegetative-stage nutrient ratio into flowering often produce smaller, slower-developing buds and fruit than their genetics allow. SUPERthrive Bloom Plant Nutrients shifts the balance toward phosphorus and potassium with a 3-12-6 NPK ratio, matching nutrient delivery to what a flowering plant actually draws on during bud and fruit set.

At 32oz, this size suits regular indoor and greenhouse growers dosing a working reservoir through a full flowering cycle. Sold in cases of 12, it's built for growers who go through bloom nutrients on a recurring schedule.

Key Features & Benefits

• 3-12-6 NPK ratio — shifts nitrogen down and phosphorus and potassium up to match a flowering plant's nutrient demand.
• Liquid concentrate formula — mixes directly into reservoir water or a feeding solution without pre-dissolving dry salts.
• Phosphorus-forward profile — supports bud and fruit set during the flowering transition.
• 32oz bottle size — sized for a working reservoir over a full bloom cycle without excess unused product.
• Case of 12 — matched to growers running bloom nutrients on a recurring feeding schedule.

Who Should Use SUPERthrive Bloom Plant Nutrients

Growers transitioning plants from vegetative growth into flowering who want a phosphorus- and potassium-forward formula matched to bud and fruit development, from home growers running a single reservoir to commercial operations feeding multiple rooms.

About SUPERthrive Nutrients

SUPERthrive has manufactured plant care products for growers for decades, with its bloom nutrient line formulated specifically to support the flowering and fruiting stage rather than vegetative growth.

Frequently Asked Questions

Why switch to a bloom-specific nutrient instead of using one formula year-round?

A 3-12-6 ratio directs more phosphorus and potassium to the plant during flowering, nutrients that support bud and fruit set more directly than the higher-nitrogen ratios used during vegetative growth.

When should I switch from vegetative to bloom nutrients?

Most growers switch at the first visible sign of flowering, such as pistil or bud site formation, to align nutrient delivery with the plant's shift in nutrient demand.

How does this differ from a general-purpose all-in-one fertilizer?

An all-in-one formula holds a fixed NPK ratio through the whole grow cycle, while this bloom-specific formula concentrates phosphorus and potassium delivery during the stage that uses them most.

Can this be used alongside other bloom boosters or additives?

Yes, it's formulated as a base bloom nutrient and can typically be combined with supplemental bloom boosters, though growers should track total nutrient concentration to avoid overfeeding.

Is this suitable for both soil and hydroponic feeding?

Yes, the liquid concentrate mixes into a feeding solution for soil, coco, or hydroponic reservoir applications.
