House & Garden Roots Excelurator SILVER 500ml (For DWC & Reservoirs)

What is House & Garden Roots Excelurator Silver used for?

Roots Excelurator Silver is a high-performance root stimulator for hydroponic and recirculating systems. It promotes fast root development, supports white root growth, and helps protect the root zone from stress and pathogens.

When should I use Roots Excelurator Silver during the grow cycle?

Start using it from seedling or cutting stage through early flowering. Most growers stop after early flower once roots are well established and the plant shifts to bulk production.

Can I use Roots Excelurator Silver for cuttings or to reduce transplant shock?

Yes, it’s ideal for early-stage rooting and helping plants recover quickly from transplanting by encouraging strong root development and reducing stress.

Is Roots Excelurator Silver safe for hydroponic systems like DWC, RDWC, or drip setups?

Yes, it’s designed for clean running in hydroponic and recirculating systems, including DWC, RDWC, drip lines, and even autopots. Just maintain good hygiene and cool water temps.

Can I use Roots Excelurator Silver with other nutrients or additives?

Yes, it works with most nutrients including Cal-Mag, bloom boosters, and PK additives. Always mix in the correct order: water first, then Silver, then other nutrients. Never mix concentrates directly together.

Can I use Roots Excelurator Silver in a sterile or oxidizing system?

No. Avoid using it with hydrogen peroxide, chlorine, or similar sterilizers—they kill the beneficial microbes. Wait until any sterilizing agent has fully dissipated before reintroducing Silver.

What’s the difference between Roots Excelurator Silver and Gold?

Silver is cleaner and better for hydro/recirculating systems. Gold is more microbe-rich and suited to soil or coco. Using the right version for your grow medium ensures better performance.

What are the benefits of Roots Excelurator Silver for plant growth?

It boosts feeder root production, enhances nutrient uptake, reduces veg time, and can improve plant health and yield. It also helps make root zones more resistant to rot and stress.

What’s the correct dose of Roots Excelurator Silver and how do I measure it?

Use about 0.3 mL per litre (1.1 mL per gallon). For 10L, use ~3 mL; for 100L, ~30 mL. Measure accurately with a syringe or pipette. It slightly affects EC and pH, so always check your final mix.

Will Roots Excelurator Silver clog lines or create foam?

It’s low-foam and designed to minimize clogging in hydro systems. Still, proper mixing and reservoir hygiene are essential to prevent buildup or issues in fine tubing.

How should I store Roots Excelurator Silver?

Store sealed in a cool, dark place. Shake well before each use. Use before the expiry date and discard if it smells rancid or looks contaminated.

Which bottle size should I buy?

250 mL is ideal for small grows or trials. 1 L suits regular users running hydro consistently. A little goes a long way, so base your choice on usage volume.

What’s the biggest mistake users make with Roots Excelurator Silver?

Mixing it with sterilizing products like peroxide. For best results, run it consistently in a clean system, follow dosing instructions, and don’t stack too many root additives.
