House & Garden Nitrogen Boost, 1 L

Nitrogen Customization Additive for Flowering, 1 L

Many feeding programs taper nitrogen sharply once flowering begins, but not every variety responds well to that steep a cutback, and foliage that pales too early can signal a nitrogen shortfall rather than a normal part of the flowering transition. Nitrogen Boost lets growers customize a plant's nitrogen level on top of a base program to help maintain green color, sized at 1 L.

This 1 L size fits a home grower fine-tuning nitrogen levels across a modest number of plants.

Key Features & Benefits

• Customizes Nitrogen Levels — Allows growers to adjust a plant's nitrogen intake beyond what a standard base program supplies.
• Maintains Green Color — Helps keep foliage green by supplying additional nitrogen on top of a base feed.
• Usable Deep Into Flowering — Certain varieties can continue using it well into the flowering stage, past when many programs taper nitrogen.
• Part of the House & Garden Line — Formulated to layer onto a House & Garden base nutrient program.

Who Should Use Nitrogen Boost

Growers working with varieties that benefit from extended nitrogen availability, or who want finer control over nitrogen levels during flowering, will find this additive useful.

About House & Garden

House & Garden is a nutrient and additive brand established in 1990 by William Van De Zwaan, whose family had a background in Dutch horticultural glasshouse production; the company formulates its base nutrients and additives in small batches, filtering its process water through multi-stage ceramic filtration. Hydrofarm acquired House & Garden in 2021, and the brand's manufacturing and research operations are based in Humboldt County, California, building a product line of base nutrient systems and root, flowering, and growth additives sold to growers in dozens of countries.

Frequently Asked Questions

What does Nitrogen Boost help with?

Nitrogen Boost helps growers customize a plant's nitrogen level on top of a base program to maintain green foliage color. It is meant to correct or prevent premature paling rather than push overall growth.

Can Nitrogen Boost be used during flowering?

Yes, certain varieties can continue using it deep into the flowering stage, later than many standard feeding programs taper nitrogen. Whether a given variety benefits from that extended use varies by strain.

How do I know if my plants need Nitrogen Boost?

Foliage that pales or yellows earlier than expected during flowering, despite an otherwise normal base program, is the main signal growers look for. Not every variety needs the extra nitrogen, so it is applied selectively rather than as a routine addition.

Is Nitrogen Boost meant for every variety?

It is most useful for varieties that benefit from extended nitrogen availability rather than every variety across the board. Check how a given variety typically responds to nitrogen tapering before adding it to a flowering program.

Does Nitrogen Boost replace a base nutrient program?

No, it is formulated to layer onto an existing House & Garden base nutrient program rather than replace it. Continue running the base program and add Nitrogen Boost where extra nitrogen is called for.
