Root Stimulators & Veg Boosters

Root stimulators are designed to kickstart rapid root development and help plants establish a strong foundation for growth. Whether added directly to your feed water or applied as a foliar spray, root boosters encourage faster root elongation, thicker root mass, and improved nutrient uptake. We stock a full range of root stimulator additives suitable for hydroponics, coco, and soil systems.

Why Use Root Stimulators?

• Accelerates root initiation in seedlings and cuttings
• Promotes stronger, more resilient root systems
• Improves nutrient absorption and water uptake
• Helps plants recover faster from transplant stress

How to Apply Root Boosters

• In Feed Water: Most root stimulators are added to your regular nutrient solution to encourage continuous root growth throughout early veg and beyond.
• As a Foliar Spray: Some root enhancers can also be misted onto leaves, where nutrients are absorbed directly and quickly transported to the root zone.

Types of Root Stimulators

Liquid Root Additives

Simple to mix into your feeding schedule. Contain natural extracts, hormones, or vitamins that stimulate root growth.

Biostimulant Root Boosters

Made with beneficial microbes, humic/fulvic acids, or kelp extracts. Support overall rhizosphere health and resilience.

Foliar Root Sprays

Fast-acting sprays absorbed through the leaf surface. Useful for seedlings and stressed plants that need quick recovery.

When to Use Root Stimulants

• During propagation (seedlings and cuttings)
• After transplanting into a new medium
• Early vegetative stage to maximise root mass
• Whenever plants show slow root growth or stress

Root Stimulator FAQs

Can I use root stimulators in hydroponics?

Yes. Many root boosters are clean and fully soluble, making them safe for hydro, coco, and soil systems.

Are foliar root sprays effective?

Yes. Foliar sprays allow for fast uptake through the leaves, giving plants a quick boost while also supporting root development below ground.

When should I stop using root boosters?

They’re most effective during propagation, transplanting, and early veg. Once roots are well established, you can reduce or stop use, depending on the product.

Do root stimulators replace base nutrients?

No. Root additives are supplements, not complete feeds. They should be used alongside your regular base nutrients.
