House & Garden Root Stimulator 1

Build a stronger root system before the plant needs one

House & Garden Root Stimulator 1 is an early-stage root additive that builds strong, healthy roots and improves the rhizosphere in the first weeks after a cutting or seedling is potted on. It's simple to use, dosed straight into the feed water, and works with most substrates and growing systems - soil, coco, rockwool and hydro. Get the root zone working properly early and it pays off later in stronger stems, better nutrient uptake and a more resilient plant right through to harvest.

Key Benefits

• More fine roots and root hairs - encourages an extensive network, not just a thicker taproot.
• Healthier rhizosphere - supports the beneficial microbes and enzymes around the roots.
• Faster nutrient uptake - a stronger root zone takes up water and feed more efficiently.
• Drives early growth - supports the rapid cell division of the first vegetative weeks.
• Easy to run - works in any substrate or watering system.

Cuttings and seedlings slow to establish?

When cuttings sulk for days after potting on, or seedlings sit still instead of pushing new growth, the root system usually isn't developed enough to support the canopy above. Getting the rhizosphere active in these first weeks is what sets up strong later growth.

How to Use

• All substrates and systems: 1ml per litre of feed or reservoir water.
• When: the first 5 weeks of vegetative growth, at every watering.
• Then: move on to your regular vegetative and flowering nutrients.
• Tip: check pH after mixing into the reservoir.
