Step-by-Step Usage Guide

1. Preparation: Shake the bottle well before use. Ensure you are in the vegetative growth phase; do not apply during flowering.
2. Mixing: Dissolve 2 to 4 ml of Cupro Plus+ Eco per liter of water. For best results, adjust your water's pH to between 4.5 and 5.5 using a pH corrector.
3. Application: Thoroughly spray the entire plant, ensuring you cover the underside of the leaves where pests and fungi often hide. Use a fine mist for even coverage.
4. Timing: Apply either as a preventative every two weeks or at the first sign of infection. Avoid application during periods of extreme heat or direct, intense sunlight.
5. Safety: Do not mix with products that have a basic (high) pH. Always wear gloves and consider eye protection when handling.
6. Storage: Keep the bottle tightly sealed in a cool, dry place away from children and pets.

Frequently Asked Questions

Can I use Cupro Plus+ Eco during the flowering stage?

No, it is strongly recommended to use Cupro Plus+ Eco only during the vegetative phase. Applying copper-based products during flowering can leave residues on the buds.

How often should I apply it as a preventative?

For preventative care, applying Cupro Plus+ Eco every two weeks is recommended. This maintains a protective barrier on the plant surfaces.

What's the difference between this and baking soda or milk sprays?

While home remedies can offer mild suppression, Cupro Plus+ Eco contains a measured, effective concentration of copper sulfate, providing reliable, proven control and prevention of serious fungal diseases.

Is it safe for organic growing?

Copper sulfate is accepted in many organic farming protocols as a fungicide. However, always check your specific certification body's guidelines. Cupro Plus+ Eco is formulated to be plant-friendly when used as directed.

Why is the pH of the mix so important?

The effectiveness of copper ions is maximized in a slightly acidic environment (pH 4.5-5.5). Maintaining this pH ensures the product works at its peak efficiency.

Personal Experience of Pevgrow’s CEO (Alan)

Let's be real, mildew is the bogeyman of the indoor grower. I've lost count of the times I've seen a perfect crop start to get those tell-tale white specks, and your heart just sinks. That's why I keep Cupro Plus+ Eco on my shelf. It's not my everyday feed, but it's my insurance policy. I use it strictly as a preventative during veg, especially when humidity starts to creep up or if I'm bringing new clones into the space. A light spray every other week is all it takes. The key for me is the pH adjustment—I mix it into my nutrient solution after I've already pH'd it down to around 5.2, and I make sure to get under those leaves. It leaves a slight bluish tinge, which is just the copper doing its job. Compared to more systemic fungicides, I like that this is a contact treatment; it sits on the surface and acts as a shield. It's straightforward, it works, and it lets me sleep easier knowing I've given my plants that extra layer of defense before they ever hit the flowering tent.
