House & Garden Top Booster, 5 L

Ripening-Stage Nutrient Additive for Flowering, 5 L

House & Garden's flowering additives are designed to layer on in a specific sequence, and skipping the ripening-stage step can leave later additives working against a plant that isn't primed for them yet. Top Booster supplies nutrients aimed at the ripening stage of flowering, setting the stage for Bud-XL and Shooting Powder later in the same cycle.

This 5-liter bottle is sized for a regular indoor or small commercial grower dosing Top Booster across multiple reservoirs.

Key Features & Benefits

• Ripening-stage formula — targeted at the specific point in flowering that precedes Bud-XL and Shooting Powder.
• Sequenced additive system — designed to work as part of House & Garden's staged flowering program, not as a standalone product.
• Layers onto a base feed — added alongside your existing base nutrients rather than replacing them.
• Multiple sizes — available from 250 milliliters up to 20 liters.

Who Should Use Top Booster

Growers already running House & Garden's base nutrients who are following the brand's staged flowering additive sequence, rather than looking for a single standalone bloom booster.

Frequently Asked Questions

When in the flowering cycle should I use Top Booster?

Use it during the ripening stage of flowering, ahead of when you'd introduce Bud-XL and Shooting Powder in House & Garden's staged additive sequence. Using it out of sequence may mean the later additives aren't working with a plant that's been primed correctly.

Do I still need my base nutrients?

Yes, Top Booster is an additive layered onto an existing base feeding program, not a replacement for it. Keep running your base nutrients and add Top Booster alongside them.

What's the difference between Top Booster and Shooting Powder?

Top Booster targets the ripening stage that comes before Bud-XL and Shooting Powder in House & Garden's sequence, while Shooting Powder is a later-stage potassium-phosphorus powder. They're designed to be used at different points in the same flowering cycle rather than interchangeably.

What sizes does Top Booster come in?

It's available from a 250-milliliter bottle up to a 20-liter container, so a grower can match the size to a small home garden or a larger commercial operation. Larger sizes reduce how often you need to reorder for a bigger number of reservoirs.

Can I use Top Booster without the rest of the House & Garden additive line?

You can, but it's formulated as part of a staged sequence alongside Bud-XL and Shooting Powder, so using it in isolation may not deliver the full intended effect. Growers new to the line may want to review House & Garden's feed chart to see how Top Booster fits into the full program.
