Emerald Harvest Bloom | 6gal

Bloom-Phase Base Nutrient with Chelated Micronutrients, 6gal

Flowering and fruiting plants shift toward a phosphorus- and potassium-heavy nutrient demand, and unchelated trace minerals can become less available to roots as media pH drifts during that stage. Emerald Harvest Bloom 0-5-4 is formulated for the bloom phase with chelated iron, copper, manganese, and zinc, keeping those micronutrients available across a wider pH range than an unchelated source would.

The 6gal size fits larger home operations or small commercial growers feeding Bloom across a bigger flowering crop.

Key Features & Benefits

• 0-5-4 NPK ratio — phosphorus- and potassium-weighted for the bloom and fruiting phase.
• Chelated iron, copper, manganese, and zinc — stay plant-available across a wider pH range than unchelated forms.
• Single-bottle bloom feed — a complete bloom-phase base nutrient rather than one half of a two-bottle pair.
• Flexible dosing — follow the printed feed chart as a starting point, then fine-tune rates to your own results.
• Works across growing media — suited to hydroponic reservoirs, coco coir, and other common bloom-phase setups.

Who Should Use Emerald Harvest Bloom

This single-bottle feed fits growers moving plants from Emerald Harvest Grow into the flowering phase who want one bloom-phase concentrate rather than managing a two-bottle Cali Pro Bloom A/B pair.

About Emerald Harvest

Bloom 0-5-4 completes Emerald Harvest's original three-part base nutrient system, the line the Santa Rosa, California company built its 2015 launch around before later adding the two-part Cali Pro alternative.

Frequently Asked Questions

What does 'chelated' mean for the micronutrients in this formula?

Chelation binds a mineral like iron or zinc to an organic molecule that keeps it soluble and plant-available across a wider range of media pH than the mineral would be in its raw form. Without chelation, those micronutrients can bind to media and become unavailable to roots as pH shifts.

Is Bloom a complete bloom-phase feed on its own?

Yes, Bloom's 0-5-4 ratio with its chelated micronutrients is meant to function as a complete single-bottle bloom-phase base nutrient, unlike the two-bottle Cali Pro Bloom A/B pair. It doesn't require a second bottle to round out the nutrient profile.

When should I switch from Grow to Bloom?

Switch when your plants transition from vegetative growth into the flowering phase, following the Emerald Harvest feed chart for timing specific to your crop. Continuing Grow past that transition doesn't supply the phosphorus- and potassium-heavy nutrition flowering plants need.

Can I add supplements like King Kola or Honey Chome alongside Bloom?

Yes, Bloom is designed to work alongside Emerald Harvest's bloom-phase supplements, which layer additional support on top of the base nutrient rather than replacing it. Check the feed chart for recommended combinations and rates.

What growing media is Bloom compatible with?

It's formulated for hydroponic systems, coco coir, and a range of other growing media used during the flowering phase. Check label directions for media-specific rate adjustments.
