Who’s This For?

  • Growers who want rapid, heavy flowering results
  • Hydroponic, coco, or soil growers looking to push yields further
  • Anyone needing a proven bloom booster for early or late flowering
  • Serious growers looking for commercial-grade results

Why Use The OG Rapid Flower and Hardener?

  • ✅ Immediate flower response — fast onset of blooming
  • ✅ Increases flower density and overall bud mass
  • ✅ Works in hydro, soil, or coco systems
  • ✅ Use early, late, or both for big uniform gains
  • ✅ Helps produce tighter, heavier flowers
  • ✅ Great for shortening internodes and stacking blooms

How to Use

Hydroponics: Apply 1–2ml per litre for 5–7 days once plants reach desired height, just as you flip to flower. For extra hardening, repeat in weeks 6–7.

Soil: Follow the hydro method, but flush with fresh water after 7 days.

Coco (hand-fed): Follow the soil method. For recirculating or run-to-waste systems, follow hydro instructions.

Pro Tip: You don’t have to use it in early flower — but if you do, you’ll get better uniformity across the plant. Always adjust your pH to 6.0 for best results.

Packaging Options

This product is manufactured in 1L bottles. Smaller 250ml bottles are decanted by us in-house to give you a flexible, cost-effective option to trial or supplement your grow.
