pH Down GHE – Dry pH Regulator for Growth and Flowering

You can have the best lights and the most expensive nutrients in the world, but if the acidity of your water isn't in the sweet spot, your plants are basically on a hunger strike. pH Down by GHE (General Hydroponics Europe) is the professional solution to lower the pH of your nutrient solution, ensuring that your weed can absorb 100% of the food you give it.

Why are your plants turning yellow despite being fed?

Problem: You are strictly following the feeding chart, measuring the milliliters, and pouring love into your grow, but the leaves are turning yellow, showing spots, or simply not growing as they should. You think it's a deficiency, so you add more fertilizer.

Agitation: Stop! If you add more food without checking the pH, you are only making the problem worse. When the pH is too high (alkaline), the roots suffer from "nutrient lockout." Basically, the door to the buffet is closed. You are wasting money on fertilizers that your plants literally cannot eat, and you are stressing the crop, risking the quality and quantity of your final harvest.

Solution: The answer is simple: adjust the acidity. With pH Down GHE, you lower the pH to the optimal range (usually between 5.5 and 6.5). This opens the "doors" of the roots, allowing calcium, magnesium, and NPK to enter freely. Plus, being a premium product from GHE (General Hydroponic Europe), it doesn't just lower acidity; it stabilizes it.

Maximum Concentration and Stability in Dry Format

Unlike common liquid acids that are basically diluted water, this product comes in a dry (powder) format. This isn't just about saving space; it's about purity. Being dry, it is harmless until mixed with water, making it safer to ship and store. But once dissolved, it becomes a potent acid that acts fast.

Furthermore, it's not just acid. GHE has formulated this regulator to provide a slight amount of nutrients (Nitrate, Phosphate, and Magnesium) that help the plant during the regulation process, something generic acids don't do.

• Benefit: You save money in the long run because the bottle lasts for many crops, and you ensure your water stays at the right level longer.

• Feature: Contains buffering agents and supplementary nutrients.
• Advantage: Prevents sudden pH swings and feeds the plant while adjusting the water.
• Benefit: Your plants grow stress-free, with green, healthy leaves, ready to produce heavy, resinous buds.

• Feature: Compatible with all substrates (Hydro, Coco, Soil).
• Advantage: Versatility to use it in any cultivation system you have set up.
• Benefit: You don't need to buy different products if you decide to switch from soil to hydroponics; this one jar does it all.

How to use pH Down GHE correctly

Using this regulator is an art that requires precision. Since it is very potent, we recommend you go slowly. Always use measuring instruments like a digital pH meter to check the levels.

1. Standard Dosage: Add approximately 1g per 5 or 6 liters of water to adjust the solution.
2. Foliar Application: Use 1g per 10 liters of water (only if strictly necessary and with low EC).
3. Cleaning: To clean systems and substrates, use 1g per liter of water, let it sit overnight, and rinse well.
4. Process: Add the nutrients to the water first, mix, measure the pH, and then add pH Down dissolved in a little water. Measure again.

⚠️ Safety Warning: Although it is powder, once it touches water it becomes a strong acid. Always wear gloves and safety glasses. If it splashes on you, wash with plenty of water immediately. Keep out of reach of children.

Frequently Asked Questions

When should I use pH Down?

You should use it whenever your nutrient solution is above the optimal range (usually above 6.5 for soil or 6.2 for hydro) after adding all your cannabis fertilizers.

Can I use it in flowering?

Yes, absolutely. It is suitable for both the growth and flowering phases. In fact, maintaining the correct pH in flowering is crucial for the buds to fatten up properly.

What happens if I lower the pH too much?

If you go overboard and the pH drops below 5.0, you can cause acid burn or block other nutrients. If this happens, you will need to add more water or use a pH Up product to balance it again.

Personal Experience of Pevgrow’s CEO (Alan)

I'll be honest with you: I used to underestimate the importance of pH when I started. I thought, "it's just water, right?" Big mistake. Since I started using GHE's dry pH Down, the change in my crops was night and day. What I like most about this specific version is that, being a powder, I don't feel like I'm paying for water, and it's super easy to dose without making a mess. A small teaspoon is usually enough to fix a large tank. It's a "must-have" in my grow room cabinet, right next to the EC meter.
