Emerald Harvest Grow | 6gal

Single-Bottle Vegetative Base Nutrient, 2-1-6 NPK, 6gal

Managing a two-bottle base nutrient system means mixing each part separately every time you feed, which is an extra step some growers would rather skip during the vegetative phase. Emerald Harvest Grow packs nitrogen, phosphorus, and potassium into a single 2-1-6 concentrate instead, giving growers a one-bottle option for vegetative feeding as an alternative to the brand's two-bottle Cali Pro Grow A/B pair.

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

Key Features & Benefits

• Single-bottle formula — nitrogen, phosphorus, and potassium in one concentrate rather than a two-bottle pair.
• 2-1-6 NPK ratio — built for vegetative-phase feeding.
• Label or custom feeding — follow the Emerald Harvest chart or adjust rates into your own program.
• Multi-media compatible — works in hydroponic reservoirs, coco coir, and other common growing media.
• Supplement compatible — layers with Emerald Harvest's supplement and additive lineup as part of a fuller program.

Who Should Use Emerald Harvest Grow

This single-bottle feed fits growers who'd rather manage one vegetative-phase concentrate than mix a two-bottle Cali Pro pair every feeding, whether they're running a home setup or a commercial vegetative room.

About Emerald Harvest

Emerald Harvest launched its original three-part Grow, Micro, Bloom base nutrient system when the Santa Rosa, California company was founded in 2015, offering growers a single-bottle-per-stage alternative to its later two-part Cali Pro line.

Frequently Asked Questions

Is Grow a complete vegetative feed on its own?

Yes, Grow's 2-1-6 ratio supplies nitrogen, phosphorus, and potassium as a single-bottle base nutrient, unlike the two-bottle Cali Pro Grow A/B pair that splits the same nutrient categories across two containers. It's meant to be a complete vegetative-phase base rather than one half of a pair.

How is Grow different from Cali Pro Grow A and B?

Grow combines all three primary macronutrients into one bottle, while Cali Pro splits them across a Grow A and Grow B pair to keep certain ions separated until dilution. Both approaches are valid vegetative-phase options; the difference is single-bottle simplicity versus two-bottle ion separation.

Can I add supplements on top of Grow?

Yes, Grow is designed to be compatible with Emerald Harvest's supplement and additive lineup, such as Cal-Mag or Sturdy Stalk, layered on top as part of a fuller feeding program. Check the Emerald Harvest feed chart for recommended combinations and rates.

When should I switch from Grow to Bloom?

Switch when plants transition from vegetative growth into the flowering phase, following the Emerald Harvest feed chart for specific timing. Growers typically move from Grow to Bloom 0-5-4 at that transition rather than continuing Grow through flowering.

What growing media works with Emerald Harvest Grow?

It's formulated for hydroponic systems, coco coir, and a range of other growing media. Check label directions for any media-specific rate adjustments before switching between systems.
