Trabe Ultrahemp is the biological ace up your sleeve to trigger explosive flowering and protect your crop from environmental stress. This stimulator, based on treated brown algae and high molecular weight biosaccharides, acts as a protective shield that optimizes hydration and nutrient uptake, ensuring your plants focus 100% on producing buds.

Why your plants need a boost like Ultrahemp

Have you ever walked into your grow room or checked your outdoor garden on a hot day only to find your plants looking sad, droopy, and dehydrated? It’s a terrible feeling. When plants suffer from heat stress or lack of water, they shut down their metabolic processes. Instead of growing or flowering, they go into "survival mode," stalling development and wasting the energy they should be using to fatten up flowers.

If you don't address this, the consequences are clear: stunted growth, nutrient lockout, and a mediocre harvest with airy, lightweight buds. You end up spending more money on water and Cannabis fertilizers because the plant simply isn't absorbing them efficiently due to excessive transpiration. It’s a cycle of waste that hurts both your wallet and your final yield.

The solution is Trabe Ultrahemp. By spraying this biostimulator, you create a microscopic, breathable film on the leaves. This barrier drastically reduces water loss through perspiration without blocking gas exchange. The result? Your plants stay hydrated longer, absorb nutrients more effectively, and receive a clear hormonal signal to start flowering immediately. It turns a stressful environment into a productive paradise.

What it feels like to grow with Trabe Ultrahemp

Using Ultrahemp gives you a sense of security, especially during those critical weeks when the weather gets unpredictable or your indoor lights are cranking out heat. Physically, you will notice the difference in the turgidity of the leaves; they stand up praying to the light, looking lush and deep green, even when temperatures rise slightly above the ideal range.

Emotionally, it’s a relief. You stop worrying about coming home to wilted plants. There is a certain pride in seeing your crop transition into the flowering stage with such vigor. It feels like you are hacking the plant's biology, giving it the "superpower" to resist thirst and focus entirely on generating resin and flowers. It’s the difference between a crop that survives and one that thrives.

How to squeeze the experience to the max

To get the best results with this algae-based wonder, you need to apply it correctly. Here are some pro tips:

  • Timing is key: Apply it just before the flowering stage begins and during the first weeks of bloom to trigger bud sites.
  • Foliar application: This product is designed to be sprayed. Make sure to spray both the top and underside of the leaves for maximum absorption.
  • Lights off: Always spray when the lights are about to go off (indoors) or at sunset (outdoors) to avoid the "lens effect" burning your leaves.
  • Stress management: If you anticipate a heatwave, apply it 24 hours before to prep the plants.
  • Don't overdo it: A fine mist is enough; you don't need the plant dripping wet to the point of runoff.
  • Combine wisely: It works great alongside soil regenerators like Microplant Solar by Trabe for a full organic approach.

Advantages and benefits in your day-to-day life

  • Water Conservation: Because it reduces perspiration, you won't need to water as frequently, giving you more freedom.
  • Nutrient Efficiency: It helps retain nutrients within the plant structure, meaning every drop of fertilizer you use is actually utilized.
  • Stress Resistance: Acts as a buffer against drought and high temperatures, saving your crop from environmental disasters.
  • Explosive Flowering: The biosaccharides and algae extracts provide the hormonal push needed to kickstart bud production faster.
  • Organic Certification: Being a Trabe product, you know it's safe, natural, and leaves no toxic residues on your final product.

How it fits with other products in your set-up

Trabe Ultrahemp is a versatile team player. Since it is applied via foliar spray, it doesn't interfere with the nutrient solution you feed the roots. It pairs perfectly with any base fertilizer schedule.

For the ultimate organic setup, combine it with other Trabe products. For example, while Ultrahemp protects the leaves and stimulates flowers, you can ensure the root zone is healthy with beneficial microbes. Also, since healthy plants are tasty to bugs, keep some Insecticides cannabis on hand, although a healthy, stress-free plant is naturally more resistant to pests.

Frequently Asked Questions

When should I start using Ultrahemp?

The ideal time is just before the photoperiod change (or when autoflowers show sex) to stimulate flowering, and then periodically during high-stress situations.

Can I mix it with other foliar sprays?

It is generally best to apply Ultrahemp alone to ensure the film forms correctly on the leaf surface. If you need to apply insecticides, try to space them out by a few days.

Is it suitable for hydroponics?

Absolutely. Since it is a foliar spray, it is independent of your root medium. It is actually very beneficial in hydro systems where water uptake is rapid.

Does it affect the flavor of the buds?

No, as long as you stop foliar applications once the buds start to form dense clusters (mid-flowering) to avoid moisture trapped inside the bud itself. The product itself is organic and leaves no chemical taste.

Personal Experience of Pevgrow’s CEO (Alan)

I remember one summer in Spain where the heat was absolutely brutal, hitting 35°C (95°F) in the shade. My indoor setup was struggling, and the plants were drinking water faster than I could supply it. I decided to give Ultrahemp a try as a desperate measure. I sprayed them just as the lights went out.

The next day, the difference was night and day. The leaves were perky, not drooping, and the soil was still moist, meaning the plants weren't sweating out all their hydration. It saved that harvest. Since then, I always keep a bottle handy for the transition to flower or whenever I know the temperatures are going to spike. It’s one of those "safety net" products that pays for itself by saving just one plant.
