Rootmax by Green Hope is the definitive tool to transform a standard crop into a high-performance beast, acting directly on the engine of your plants: the root system. This bio-stimulator is not just another additive; it is a powerful biological activator that awakens the bacterial life of the substrate, ensuring that your plants develop a massive root mass capable of devouring every nutrient you give them.

Why are weak roots ruining your harvest?

Have you ever felt that your plants are stuck, growing slowly, or looking fragile despite giving them the best fertilizers? The problem is often underground. A weak root system cannot absorb food efficiently, and worse, it is the perfect target for pathogens that can kill your crop in days.

It is frustrating to spend money on expensive nutrients if your plants are unable to assimilate them. Furthermore, the constant threat of fungi like Pythium or Fusarium adds unnecessary stress to your grow. If the roots don't work, the plant doesn't eat, the buds don't fatten, and you lose time and money.

Rootmax is the solution to shield and supercharge your underground zone. By stimulating the micro-life of the substrate, it creates a defensive barrier against fungi and accelerates root development to levels you haven't seen before. With this product, you ensure that every drop of water and fertilizer is used to create structural mass and flowers.

How Rootmax improves your grow

Using this bio-stimulator changes the rules of the game. Here is how it transforms your setup:

  • Biological Activation: It acts as a catalyst for beneficial bacteria, improving the soil structure and nutrient availability.
  • Fungal Shield: It significantly reduces the risk of root rot caused by Pythium and Fusarium.
  • Nutrient Uptake: By increasing the root mass, the plant demands more food (you may need to increase your fertilizer dose by 10%), which translates directly into explosive growth.
  • Versatility: Although it works in soil and coco, it is especially effective in Hydroponic and Aeroponic Systems where root health is critical.

Advantages and benefits of Green Hope Rootmax

Why choose this stimulator over others? Here is the FAB breakdown:

  • Ultra-Concentrated Formula: Because you only need 1 ml for every 10 liters of water, a small bottle lasts for many crops, which means huge economic savings for you.
  • Accelerated Metabolism: Because it speeds up root expansion, the vegetative phase can be shortened, which means faster harvests.
  • Stress Resistance: Because it strengthens the root wall, your plants tolerate changes in pH or temperature better, which means greater peace of mind and security for you.
  • Flavor and Yield: Because the plant eats better, the final production increases and the terpene profile improves, which means tastier and heavier buds.

How to use Rootmax correctly

To get the most out of this product and not damage its biological components, follow these steps:

  1. Dosage: Add only 1 ml of Rootmax for every 10 liters of irrigation water.
  2. Mixing: Never mix it pure with other fertilizers. Dilute your organic fertilizers in the water first, check the pH, and add the bio-stimulator last.
  3. Frequency: Green Hope recommends using it frequently (in every irrigation or every other irrigation) but always respecting the low dosage.
  4. Monitoring: Since your plants will eat more, watch for signs of deficiency (Iron, Potassium, Calcium) and increase the base food if necessary.

Frequently Asked Questions

Can I use it in flowering?

Yes, although it is a root stimulator, maintaining a healthy root system during flowering ensures that the plant has energy to fatten the buds. You can use it throughout the cycle.

Does it affect the pH of the water?

Being a highly concentrated product, its impact on pH is minimal once diluted, but you should always measure the pH after adding all nutrients to the tank.

Is it compatible with mineral fertilizers?

Yes, Rootmax works excellently with both mineral and organic lines, as its function is to stimulate the absorption of whatever is in the substrate.

Personal Experience of Pevgrow’s CEO (Alan)

I have tried many root stimulators over the years, but the concentration of Green Hope's Rootmax is insane. The first time I used it in a hydro system, I was surprised by how white and hairy the roots looked in just a few days. It's like they grew a beard overnight.

One thing I learned quickly: don't underestimate the plant's hunger when you use this. The roots grow so much that the EC of the tank drops faster than usual because the plants devour everything. My trick is to slightly raise the base fertilizer dose by 10% when I see that explosive growth starting; if you do that, the result in the harvest is brutal.
