PH- Nitric Acid Hy-Pro – pH Down Regulator for Growth Phase

PH- Nitric Acid Hy-Pro is the professional solution you need to ensure your plants eat properly during the vegetative stage. This concentrated liquid regulator lowers the pH of your nutrient solution, optimizing it so that the root system can assimilate all the available elements without restriction.

Why are your plants not growing even with the best fertilizers?

Problem: You have invested in high-quality seeds and top-tier nutrients, but your plants show yellowing leaves, slow growth, or burnt tips. You are feeding them, but they seem to be starving. This is one of the most frustrating situations for any grower.

Agitation: The culprit is almost always the pH. If the acidity level of your water is not within the correct range (usually 5.5 to 6.0 for hydroponics and slightly higher for soil), the nutrients precipitate and become "locked." It doesn't matter how much food you pour into the pot; if the pH is wrong, the plant cannot access it. You are literally flushing money down the drain while your crop suffers.

Solution: The PH- Nitric Acid Hy-Pro unlocks this potential. By adjusting the water to the optimal point, you break that barrier, allowing your plants to absorb 100% of the diet you provide. Being based on nitric acid, it is the perfect choice for the growth phase, as it solves the pH problem and contributes to the vigorous development of stems and leaves.

What this product does for you

This regulator acts immediately to neutralize the alkalinity of the water. Tap water often comes with a high pH (hard water), which is fatal for cannabis. By adding this product, you lower that value to the "sweet spot" where macro and micronutrients are chemically available to the roots.

Unlike generic acids, this formula is designed to work in synergy with the HY-PRO range, although it is compatible with any brand of nutrients. It is the key to a healthy crop without deficiencies.

Key features and benefits

• Nitric Acid Base: Ideal for the vegetative cycle, as it provides an extra shot of Nitrogen, essential for green leaves and strong stems.
• High Concentration: A very small amount is enough to regulate many liters of water, making it a durable and economical product.
• Immediate Action: You don't have to wait; the pH drops instantly, allowing you to water without delay.
• Prevents Lockout: Ensures that your Growth Fertilizers are actually assimilated, avoiding common deficiencies like iron or magnesium chlorosis.
• Versatility: Suitable for soil, coconut, and hydroponic systems.

How to use it correctly

Using acids requires caution and precision. Follow these simple steps to avoid drastic fluctuations:

1. Prepare the mix: Fill your tank with water and add all your usual fertilizers and additives first.
2. Measure: Check the initial pH level using a digital meter or drop test kit found in our measuring instruments section.
3. Dose: Add PH- Nitric Acid Hy-Pro drop by drop (or in very small milliliters) if you have a small tank. It is very powerful.
4. Mix and Re-measure: Stir the water well and measure again. Repeat the process until you reach a value between 5.5 and 6.0.

Frequently Asked Questions

Why use Nitric Acid instead of Phosphoric Acid?

Nitric acid is preferred for the growth phase because it adds Nitrogen (N), which plants need in large quantities to develop foliage. Phosphoric acid is better for flowering as it adds Phosphorus (P).

Can I use it in flowering?

Technically yes, it will lower the pH, but it is recommended to switch to a Phosphoric acid-based regulator once the buds start to form to avoid excess Nitrogen that could delay ripening.

What happens if I lower the pH too much?

If you drop below 5.0, you can damage the roots and block other nutrients. If this happens, simply add more tap water to raise the pH again before watering.

Personal Experience of Pevgrow’s CEO (Alan)

In my years of growing, I've learned that pH is the steering wheel of the crop. I used to obsess over nutrient brands, but until I started strictly controlling acidity, I didn't see real results. I use Hy-Pro Nitric Acid specifically during the first few weeks of vegetation.

I like it because it's stable. Some regulators fluctuate after a few hours, but this one holds the level well, which is crucial if you prepare tanks for automatic irrigation. Plus, that little extra nitrogen it provides is noticeable in the intensity of the green of the leaves. A bottle lasts me ages because you really need very little.
