Big One by Top Crop is a flowering stimulant that’s added alongside other base fertilizers in order to increase yield from your plants. It accelerates their internal processes, giving them plenty of complex molecules so that they don’t have to synthesize them on their own. This allows your plants to focus more energy on growing larger flowers.

This product can safely be used in automatic watering systems, as its 100% dissolvable. It can be used in almost any growing medium; soil, coco coir, aeroponics, hydroponics and NFT.

Add some Big One to your plants and you’ll be able to make the most out of this bio flowering stimulant with just 3 doses. It makes for shorter internodes, allowing light to reach the entire plant. It also increases the amount of flowers which you can fatten using Superguano,, increasing yield quite a bit. It also creates a lot more resin on your plants, which increases both potency and flavor.

Dosage and how to use:

  • 2ml per liter of water.
  • Spray once you’ve flipped the lights indoors.
  • Once the flowers begin to show on autoflowering plants.
  • Outdoors, once summer starts.
  • 10 days after spraying, repeat the process via watering with the same amount, 2ml per liter.
  • For plants that take longer to flower, you can apply once more – indica plants generally just need the previous two doses.


  • 0,4% Nitrogen.
  • 0,7% Phosphorous.
  • 2,5% Potassium.
