GreenPlanet pH Up – Premium pH Adjuster for Hydroponic and Soil Gardens

What does GreenPlanet pH Up do, and why is pH so important?

GreenPlanet pH Up raises the pH of your water or nutrient mix when it’s too acidic. In hydroponics and other grow systems, correct pH is essential—otherwise, plants can’t absorb nutrients properly, even if your feeding is perfect.

What pH range should I aim for with GreenPlanet pH Up?

Hydroponics typically runs best between pH 5.5–6.2. Coco prefers 5.8–6.2, and soil tends to be stable around 6.2–6.8. Always test your system and adjust gently—don't chase numbers aggressively.

How and when should I use GreenPlanet pH Up?

Add it after mixing all your nutrients. Dilute a small amount in water first, then add it to a circulating tank. Mix thoroughly, wait a few minutes, then re-test pH. Start small, go slow, and adjust only as needed.

Can I use too much GreenPlanet pH Up?

Yes — it’s highly concentrated, and even small amounts can swing pH fast, especially in soft water or small reservoirs. Overcorrecting is common. If you overshoot badly, it’s usually better to remix the tank than try to bounce between Up and Down.

Why does my pH barely move or swing too fast?

High alkalinity (hard water) resists change, so you may need more pH Up. Soft or RO water lacks buffering, so pH can shift too quickly. Always adjust in small doses and allow proper mixing before re-testing.

Is GreenPlanet pH Up compatible with other nutrients and systems?

Yes — it works with most nutrient brands, organic feeds, and beneficial microbes. It’s also safe for RDWC, NFT, and hand-watering mixes. Add silica and Cal-Mag first, then nutrients, then adjust pH at the end.

Why does my pH drift after using pH Up?

pH can drift due to plant uptake, reservoir temp swings, algae, or dirty tanks. Algae especially can push pH upward. Stable water, consistent temps, and a clean reservoir help maintain steady pH.

Do I need a pH pen, and how often should I check pH?

Yes — a calibrated pH meter is essential. Check pH daily, especially in hydro or fast-growing systems. If your meter seems off, calibrate it. Guessing is the fastest way to wreck your feed.

Can I use GreenPlanet pH Up with automated dosing systems?

Yes — just make sure your doser and tubing are compatible with alkaline solutions. Even with automation, always verify pH manually to avoid long-term drift or dosing errors.

Can I use GreenPlanet pH Up for foliar sprays?

It’s not recommended unless you’re experienced. Foliar sprays require gentle pH adjustment, and strong pH Up products can burn leaves if misused. Stick to reservoir use unless you know what you're doing.

Is GreenPlanet pH Up safe to handle?

It’s a strong alkaline solution. Wear gloves and eye protection, and avoid skin or eye contact. If splashed, rinse thoroughly with water and seek medical help if irritation continues.

How should I store GreenPlanet pH Up?

Store upright, sealed, and out of heat and direct sunlight. Keep away from children, pets, acids, and reactive chemicals. Don’t pour diluted or used product back into the bottle—it can contaminate the batch.

Why did my nutrient mix go cloudy after adding pH Up?

Cloudiness usually comes from mixing nutrients in the wrong order, extreme pH swings, or reactions between incompatible additives. Always follow best-practice mixing order and avoid sudden pH jumps.

Do I need to use pH Up every time I top up my reservoir?

Sometimes. It depends on your water source and how much the top-up shifts the pH. Always test after topping up and adjust only if needed—don't assume.
