Light is an input. Uniformity is a strategy. 🌱💡

In professional horticulture, delivering more light is only part of the equation. Growers need a lighting system that can deliver predictable performance across the crop while giving them control over intensity as conditions and crop demands change.

The DLI ZENITH 900W delivers 2,400 µmol/s of full-spectrum output at 2.7 µmol/J, combining high-output LED performance with dimming capability for greater control over the growing environment.

Its IP65-rated construction is engineered for demanding horticultural environments, while the fixture’s compact 98 × 21 × 13 cm design makes serious output possible without an oversized footprint.

And behind the specifications is something distinctly DLI: the ZENITH is designed and manufactured in the Netherlands, drawing on Dutch horticultural lighting experience built around professional greenhouse production.

Precision light. Higher standards.

Healthy root system is more than just a bigger root mass. 🌱

RHIZIUM was developed specifically around the rhizosphere—the active zone where roots, substrate, nutrients, and biology come together.

Its technology is designed to stimulate the development of fine root hairs and the rhizosheath, the layer of substrate particles that adheres directly to the root surface. That expanded root-zone interface can help plants make better use of the environment surrounding them.

RHIZIUM is built for more than propagation, too. It can be used throughout vegetative and blooming/fruiting phases, and the formula is compatible with all fertilizer systems and substrates. The recommended root-feed rate is 1–2 mL per gallon.

And for commercial growers running irrigation systems, there’s another detail that matters: RHIZIUM is completely water soluble and formulated without molasses, specifically to avoid the biofilm and clogged-injector problems associated with carbon-heavy root additives.

From freshly rooted clones to established production plants:

Build the interface. Support the rhizosphere. Push performance.

SiLicium feeding made simple. 🌱

For root-zone and reservoir applications:

0.5 mL SiLicium per gallon of water.

The order of addition matters. Start with your water, add SiLicium first, and mix thoroughly before adding the rest of your nutrient program.

WATER → SiLICIUM → MIX → REMAINING NUTRIENTS

SiLicium provides orthosilicic acid, a bioavailable form of silicon designed for plant uptake. Once taken up by plant tissue, silicon can contribute to reinforcement of cell walls and support stronger plant structure.

Simple application. No complicated silicon conversion process for the grower.

0.5 mL/GAL. Add first. Mix thoroughly. Feed.

Save this one for your next reservoir. 💧🌱

Powerful plant nutrition doesn’t have to be complicated. 🌱

Ruby Ful #$% is built to be an easy addition to your existing feeding routine. Shake well, add 5–10 mL per gallon of water, mix, and you’re ready to feed. It can be used throughout vegetative and blooming/fruiting stages, with the exception of the pre-harvest flush.

But simple to use doesn’t mean simple in function.

Ruby Ful #$% is formulated to support elemental transfer within the plant, help reduce salt buildup in growing media without increasing EC/PPM, and condition both tap water and the rhizosphere for improved nutrient uptake. It’s also compatible with all fertilizer systems and substrates, making it easy to work into the program you already use.

Measure. Mix. Grow.
No unnecessary complication—just an easy-to-use additive designed to help your plants make better use of what you’re already giving them.

Meet FERTiLIUM 🌱🧬

Plant nutrition is about more than what you feed—it’s about how effectively your plants can use it.

FERTiLIUM combines a targeted amino acid and peptide matrix designed to support nutrient uptake and transport, root development, chlorophyll synthesis, and overall plant metabolism.

By working alongside your existing nutrient program, FERTiLIUM helps make essential nutrients more available to the plant while supporting the biological processes behind healthy, vigorous growth.

Nature provides the building blocks. Science helps put them to work.

🌱 Use from vegetative growth through flowering and fruiting.
