Flower Multipurpose Systemic Fungicide 1L is the ultimate shield for your plants, designed to penetrate the sap stream and eliminate fungi from the inside out, ensuring total protection even on new shoots. Unlike superficial treatments that wash away, this product guarantees that your crop stays clean, healthy, and productive, tackling the most common fungal threats effectively.

Is your crop under attack by fungi?

You know the routine: you open your grow tent or walk into your garden, and suddenly you see those dreaded white spots or rusty patches on the leaves. Your heart sinks because you know that without this product, your daily routine becomes a constant battle against spreading spores, pruning infected leaves, and watching your plants lose vigor day by day.

It’s not just about the ugly spots; it’s about the stress of knowing that fungi like powdery mildew or rust can decimate your yield and ruin the flavor of your buds in record time. The frustration of spraying products that wash off with the first rain or degrade under the grow lights is real. If you don't act fast, months of work, electricity, and cannabis fertilizers could end up in the trash.

The solution is here: Flower Multipurpose Systemic Fungicide doesn't just sit on the leaf; it becomes part of the plant. By entering the vascular system, it hunts down the fungus wherever it hides and prevents it from coming back, giving you the peace of mind you deserve.

Before using this fungicide: Preparation is key

Before you start spraying like a madman, take a breath. Identify the problem correctly. Is it powdery mildew? Rust? Once identified, remove the most damaged leaves carefully so you don't spread spores. Make sure your grow room ventilation is off to avoid blowing the spray around, or wait for a calm day if you are outdoors.

  • Clean up: Remove dead plant material from the soil surface.
  • Safety first: Put on gloves and a mask; safety is sexy.
  • Timing: Plan to spray when the lights are about to go off or at sunset to avoid leaf burn.
  • Check compatibility: Ensure you haven't used incompatible products (like sulfur) recently.

During use: How to apply it effectively

Shake the bottle well. Since this is a 1L format, it often comes ready to use or easy to dose (check the label instructions specifically). Spray the plant thoroughly, but don't drown it. The magic of this product is its systemic action. You don't need to obsess over hitting every single microscopic spot because the plant will absorb the active ingredient and distribute it through its sap.

While applying, focus on the stems and the main leaves. You will feel a sense of relief knowing that once it dries, the product is "locked in." Unlike contact fungicides against oidium that wash off, this one stays working from the inside, protecting even the new leaves that haven't grown yet.

After application: Results and maintenance

A few days after application, you'll notice the fungal spread stops dead in its tracks. The white powder will turn greyish and die off. Your plants will regain their vigor, focusing their energy on growing buds rather than fighting disease. The protection lasts for weeks, meaning you can relax a bit more.

However, don't get complacent. Keep monitoring humidity levels and airflow. If you are in a high-risk area, a preventive application every 15-20 days is your best insurance policy. Remember to respect the safety period before harvest to ensure a clean smoke.

Advantages and benefits of Flower Systemic Fungicide

  • Systemic Action: It travels through the sap, protecting the whole plant, including new growth that appears after spraying.
  • Rain Resistance: Once dried, it doesn't wash off with rain or irrigation, offering long-lasting protection.
  • Curative and Preventive: It fixes existing problems and prevents new spores from taking hold.
  • Broad Spectrum: Effective against Oidium, Rust, Black Spot, and Anthracnose.
  • Cost-Effective: Fewer applications are needed compared to contact fungicides, saving you time and money.
  • Versatile: Perfect for ornamental plants, vegetables, and your precious cannabis crop.

Frequently Asked Questions

How long does the protection last?

Thanks to its systemic nature, protection can last up to 3-4 weeks, depending on the environmental conditions and the plant's growth rate.

Can I use it during flowering?

You should be careful. While effective, chemical systemic fungicides have a safety period (usually 14-21 days). Stop using it well before harvest to ensure no residues remain in your flowers.

Does it kill spider mites too?

No, this is a fungicide. For bugs, you should look into specific insecticides cannabis to handle pests like mites or thrips.

Is it ready to use?

The 1L format by Flower is typically a ready-to-use spray gun, making it incredibly convenient. No mixing, no mess. Just aim and shoot.

Personal Experience of Pevgrow’s CEO (Alan)

I've seen too many good harvests ruined by a sudden outbreak of powdery mildew just when things were looking great. What I love about the Flower Multipurpose Systemic Fungicide is the "fire and forget" aspect. When I spot the first sign of trouble in the vegetative stage or early flowering, I apply this.

The peace of mind knowing that the active ingredient is circulating inside the plant is priceless. It's particularly useful for outdoor guerilla grows where you can't visit every day to re-apply after a rain shower. My advice? Use it preventively if you know your area is humid. It’s better to spray once early than to cry later.
