Gold Label Ultra LED No.3 Boost 5L – LED Flowering Booster

Gold Label Ultra LED No.3 Boost 5L is a highly concentrated phosphorus and potassium flowering booster specifically formulated for plants grown under LED lighting.

As No.3 in the Gold Label Ultra LED nutrient range, this specialist flowering additive complements the Ultra LED Grow and Bloom nutrients during the flowering stage.

The formula has been developed specifically for the growing conditions associated with modern LED lighting, including cooler grow-room temperatures and high-EC irrigation, making it an ideal addition to a dedicated LED feeding program.

No.3 in the Gold Label Ultra LED Range

Gold Label Ultra LED No.3 Boost forms the third component of Gold Label's specialist LED nutrient program.

The system combines:

• Ultra LED No.1 Grow

• Ultra LED No.2 Bloom

• Ultra LED No.3 Boost

While No.1 Grow and No.2 Bloom provide the base nutrition, No.3 Boost is introduced during flowering to provide additional phosphorus and potassium.

This makes it easy to build a complete feeding program specifically around plants cultivated under LED grow lights.

Phosphorus & Potassium Flowering Booster

Gold Label Ultra LED No.3 Boost provides a concentrated source of phosphorus (P) and potassium (K) for use during flowering.

Phosphorus and potassium are essential macronutrients involved in numerous processes throughout plant development, making additional P and K an important part of many flowering nutrient programmes.

Ultra LED No.3 Boost is designed to supplement your base nutrients, not replace them.

Specifically Formulated for LED Growing

Modern LED grow lights create different environmental conditions than traditional HID and HPS lighting, mainly because they introduce less radiant heat into the growing environment.

The Gold Label Ultra LED range has been developed with LED cultivation in mind.

Ultra LED No.3 Boost is specifically formulated for cooler LED grow-room conditions and high-EC irrigation, providing growers with a flowering booster designed around modern LED horticultural lighting.

Suitable for All Substrates

Gold Label Ultra LED No.3 Boost is suitable for all substrates, offering flexibility across a wide range of indoor growing systems.

It is also compatible with products from the Gold Label Professional range, allowing you to incorporate No.3 Boost into a broader Gold Label nutrient program.

How to Use Gold Label Ultra LED No.3 Boost

Shake well before use.

Add Ultra LED No.3 Boost separately to your irrigation water during the flowering stage.

Dosage

0.5–1.5ml per liter of water

The dosage can be gradually increased according to the feeding program and stage of flowering.

Do not mix concentrated nutrients together in their undiluted form. Add each nutrient separately to the irrigation water.
