Description
A high-P/K booster tuned to the spectrum LED grow lights actually put out
The Gold Label Ultra LED Boost is a phosphorus and potassium flowering additive (NPK 0-15-15) developed alongside Gold Label's Ultra LED base feed to match the way plants respond under full-spectrum LED fixtures rather than legacy HPS lighting. It slots in as a straightforward late-stage top-up on top of any base feed, pushing flower and fruit development through the second half of flowering without upsetting the wider nutrient balance.
Key Benefits
- High-concentration P/K formula (0-15-15) targeted at flowering and fruiting demand.
- Developed for LED spectrum growing, alongside Gold Label's Ultra LED No.1 & No.2 base feed.
- Compatible with any base nutrient, not just the Ultra LED range, as a straight booster.
- High-concentration liquid keeps dose rates low and bottle life long.
- Dutch-manufactured to Gold Label's usual consistency and quality control.
LED fixtures push a different balance of wavelengths through the canopy than HPS, and a booster designed around older lighting doesn't always land the same way under full-spectrum LEDs. Ultra LED Boost was formulated specifically to complement that spectrum, so growers running modern LED setups get a P/K top-up tuned to their actual light source rather than a generic one.
How to Use
- Flowering weeks 3 onward: add at the manufacturer's recommended rate alongside your base feed.
- Shake well before use and introduce gradually into an existing feed schedule.
- Monitor EC/pH as with any concentrated additive, adjusting the base feed strength to compensate.
