What it is

Bio-stimulant is a fermented tonic that stimulates plant growth and development. It is made for weak and stunted plants — those that stall or delay in their growth. Stinging nettle, rich in growth compounds and micronutrients, is fermented with Mountain Microorganisms and molasses into a foliar spray that revives sluggish crops.

On the Nutritive Cycle: This is a vegetative-stage input — a push for young or lagging plants building roots and leaves. Reach for it when growth has stalled.

When to use it

  • Weak or retarded plants — spray crops showing signs of stunting or slow growth.
  • Dosage250 cc in a 20 L spray pump.

Materials

  • Stinging nettle (Urtica dioica), chopped — 3 kg
  • Activated MM — 7 L
  • Molasses — 7 L
  • Clean water — 50 L total
  • Drum, hose and water bottle for the airlock

How to make it

  1. Prep the nettle. Chop and crush 3 kg of stinging nettle.
  2. Sweeten. Dissolve 7 L molasses in 15 L water.
  3. Combine. Add the molasses solution and 7 L activated MM to the drum, then the nettle.
  4. Top up. Add the remaining 35 L water — do not fill to the top; leave gas space below the cover.
  5. Airlock. Cover and run a hose into a bottle of water so gases escape.
  6. Ferment 15 days in a cool, dry place.

Signs it worked / troubleshooting

  • Good: gas bubbles rise steadily through the water-bottle airlock during fermentation.
  • ⚠️ No bubbling = weak seal or too little MM → check the cover and airlock.
  • 🚫 Drum filled to the top = no room for gases → always leave headroom below the lid.

How to store

Keep sealed with the airlock in a cool, dry place. Ready after 15 days. Apply diluted at 250 cc per 20 L spray pump on stunted crops.
