Top Worm 4 Kg by Top Crop is the high-quality earthworm humus your substrate needs to transform from simple dirt into a living, breathing ecosystem capable of delivering the most vigorous growth you've ever seen. This 100% organic amendment is designed to improve soil structure, ensure rapid rooting, and provide that essential nitrogen kick your plants crave during the vegetative stage.

Why your plants might be struggling (and how to fix it)

Problem: Have you ever felt that, no matter how much you water or care for them, your plants seem stuck, with pale leaves and slow development? Often, the problem isn't you, but a dead or unstructured substrate that prevents roots from breathing and absorbing nutrients efficiently.

Agitation: There is nothing more frustrating than spending money on expensive seeds and lights, only to watch your crop stall. A compacted soil without microbial life is like trying to run a marathon while breathing through a straw: your plants suffer stress, become vulnerable to fungi, and you end up wasting time and resources on a harvest that will never reach its full potential.

Solution: The solution is to revitalize the medium from the start with Top Worm 4 Kg. By mixing this premium humus into your Soil For Cannabis, you are injecting millions of beneficial microorganisms and a perfect dose of natural nitrogen. It's the biological engine that turns your pot into a nutrient factory, ensuring your plants grow strong, green, and stress-free.

If you're just starting out: The safety net for your grow

If you are new to this world, Top Worm is your best ally. Unlike chemical fertilizers that can burn your plants if you miscalculate the dose, earthworm humus is gentle and self-regulating. It acts as a buffer, forgiving small errors in pH or fertilization.

  • Impossible to burn: You can use it with confidence; it releases nutrients slowly as the plant needs them.
  • Guaranteed rooting: Its fluffy texture prevents the soil from caking, allowing roots to expand effortlessly.
  • Natural defense: It helps prevent pests, reducing the need for strong Insecticides cannabis later on.

If you're an expert: The secret to Living Soil

For the veteran grower looking for organoleptic quality and maximum yield, Top Worm is the base of any "Super Soil" mix. You know that the key to terpenes is soil life, and this humus is loaded with fulvic and humic acids that chelate nutrients, making them immediately available.

  • Microbial bomb: Increases the population of beneficial bacteria and fungi in the rhizosphere.
  • Perfect structure: Improves cation exchange capacity (CEC), retaining water and nutrients more efficiently.
  • Synergy: Works perfectly when combined with other Cannabis fertilizers from the Top Crop line.

Advantages and benefits of Top Worm 4 Kg

  • 100% Organic: Made from cow, horse, and goat manure processed by worms. Zero chemicals.
  • Nitrogen boost: Provides the main macronutrient for explosive vegetative growth.
  • Water retention: Helps the substrate stay moist longer without drowning the roots.
  • pH Buffer: Helps maintain stable acidity levels in the soil.
  • Versatile: Ideal for indoor, outdoor, and guerrilla growing.
  • Harvest quality: By improving plant health naturally, the final flavor of the bud is cleaner and more potent.

Typical mistakes this product helps you avoid

Many growers fail by neglecting the substrate. Top Worm helps you avoid the most common disasters:

  • Root suffocation: Prevents the soil from becoming a block of mud, ensuring oxygen reaches the roots.
  • Nutrient lockout: By improving soil life, it prevents salts from accumulating and blocking absorption.
  • Deficiencies in growth: Provides a constant background of nitrogen so your plants don't yellow prematurely.

Frequently Asked Questions about Top Worm

How do I mix Top Worm with my substrate?

The ideal ratio is to mix between 5% and 15% of Top Worm with your substrate. For example, for every 50 liters of soil, add about 3 to 7 liters of humus. If you grow outdoors in open ground, apply 3 to 10 liters per square meter.

Can I use it for autoflowering plants?

Absolutely. Autoflowers love a spongy, airy substrate. Top Worm provides exactly that, allowing their rapid root system to develop without resistance during their short life cycle.

Does it replace liquid fertilizers?

It is an excellent base that reduces the need for liquid nitrogen during the first few weeks, but for maximum production, we recommend following the Top Crop feeding chart and supplementing during flowering.

Does it have an expiration date?

If kept in a cool, dry place away from direct sunlight, it maintains its properties for a long time. However, being a living product, it is best to use it within the season to take advantage of its microbial life.

Personal Experience of Pevgrow’s CEO (Alan)

"I've seen hundreds of growers spend a fortune on boosters and additives while ignoring the most basic thing: the soil. When I prepare my pots, Top Worm is never missing. I like to mix it at 10% with a light substrate. The difference is brutal: the plants start with a vigor that you just don't get with inert soil. Plus, it gives me peace of mind knowing that I'm creating a natural ecosystem where roots feel at home. If you want to recycle old soil or give a vitamin kick to a new mix, this 4kg bag is the perfect size to start."
