Shogun Start: Your Early Launch Game-Changer

Don’t leave the start of your grow to chance. Shogun Start sets your plants up to push hard early, striking faster, building more roots, and bouncing from cube to pot without skipping a beat. Use it with Katana Roots and you're building above-average vigour right from day one.

Packed with full-strength micro-nutrients and half-strength NPK, Shogun Start fuels growth without the burn. Precision calcium–boron ratios fire up root branching, while SmartZen® tech boosts chlorophyll and early vigour. The result? Faster strikes, stronger roots, and stress-free establishment in any system.

Why Growers Choose Shogun Start 

  • Higher strike rates — Cuttings and seedlings get moving quicker, with more consistent rooting each time.
  • Gentle yet complete feed — Packed with trace nutrients your young plants need, without risking burn or stress.
  • Built-in SmartZEN tech — Helps improve chlorophyll production and boosts early vigour from the get-go.
  • Pairs perfectly with Katana Roots — Shogun Start fuels shoots, Katana drives roots — together they give young plants the strongest launch.

The Science Behind the Take-Off

Young plants are fragile—they need everything in just the right dose. Shogun Start delivers that: trace elements that fuel root hormones, plus boron and calcium loaded for better root branching and strength.

Why Early Nutrition Matters
  • Calcium and Boron in sync — Mobilise auxins for rapid root initiation and branching.
  • Trace-rich, NPK-light — Full micronutrient support, gentle on fragile seedlings.
  • SmartZen boost — Elevates chlorophyll, accelerates photosynthesis, and cuts transplant stress.
  • Humic & fulvic synergy — Supercharges nutrient delivery and microbial root support.
The Shogun Advantage
  • Independent 3rd Party Lab Tested — Consistency you can be confident in.
  • Multi-system compatibility — Equally effective in soil, coco or hydro.
  • Built on research — Lab-led development from Dr Callie Seaman, field-tested for real growers.

Are you using water straight from the tap, or R/O water?

"Hard" and "soft" are terms used to describe the quality of many water sources. Hard water has a high mineral content, which can cause hard, white lime scale to form on surfaces and growing equipment. Hard water may also have a high alkalinity and a high pH, meaning that considerably more acid is required to lower the pH in the hydroponic system to ideal levels. Soft water, by comparison, is a low mineral water source. Often rainwater is ‘soft’, while municipal water sources across the country range from very hard to soft, depending on where the individual city water supply is taken from. Other water types Some growers prefer to start with water which has been pre-treated to remove any chemicals, pathogens and other contaminates. RO (reverse osmosis), distilled water, filtered and bottled water are all options for small growing systems and those concerned with water quality. To understand your water type, simply immerse your EC/CF meter in your background water, read the display and select the applicable 'water type' or enter your own 'Custom' value.
