Shogun Katana Roots: Give Your Plants the Cutting Edge
Strong, healthy plants are the key to achieving a thriving indoor jungle, and it all starts below the soil. Shogun Katana Roots is a powerful root stimulator designed to give your seedlings and cuttings the best possible start in life.
It doesn't just make roots grow longer; it encourages the development of a complex, efficient root system capable of maximum nutrient uptake. Whether you are propagating rare Aroids or managing a full hydroponic setup, this is the fuel your engine needs.
Please allow a 7-10 day processing time for the 1L, 5L and 10L bottles before your order is dispatched.
Why It’s a Game Changer
-
Explosive Root Growth: It drastically improves the success rate of cuttings and transplants by helping them develop large root systems quickly.
-
Disease Shield: Healthy roots are resistant roots. Continued use helps protect your plants from nasty pathogens and fungi, specifically Pythium, which can turn a flourishing root system into dark brown sludge.
-
Efficiency Boost: By creating a more complex root zone, Katana Roots improves the uptake mechanism, ensuring your plants can absorb the maximum amount of nutrients to fuel faster growth above ground.
-
Stress Recovery: It is highly effective when used as a foliar spray to help stressed plants recover quickly.
How To Use
-
For Propagation (Seedlings & Cuttings): Use 5ml per litre. You can soak your propagation media (plugs/moss) in this solution for 15 minutes before use to improve success rates. Continue to use once per week for the first 1-2 weeks.
-
For Established Plants: Once established, lower the dose to 0.2ml per litre. Use this throughout the vegetative stage and the first 3 weeks of flowering to maintain root health.
-
Foliar Spray: Mix 5ml per litre and spray 1-2 times per week to revive stressed plants.

Pro-Tip: Don't Forget the Soak If you are struggling with rooting stubborn cuttings, try the "soak method." Soaking your propagation plugs in a 5ml/L solution of Katana Roots for 15 minutes before inserting the cutting gives the stem immediate access to the stimulants it needs to pop those first roots.
