CANNA pH- Growth 17% Pro is a technical acid product for lowering nutrient-water pH during growth. It is only relevant when the solution is being measured and adjusted deliberately.

For controlled nutrient water

This product belongs with hydro, coco and advanced mineral feeding where pH is checked as part of the care step. It is not a casual add-on for everyday houseplant owners.

Before you choose it

Use it only when you need a serious acidifying tool and understand careful handling. Read the use and caution notes before handling it, because this is a technical chemical, not a casual plant additive.

CANNA pH- Growth 17% Pro is best suited to hydro, coco and semi-hydro users who already monitor pH. Relevant where tap water or nutrient mixes sit above the target range for the chosen medium.

Beginners with soil-grown plants usually need simpler feeding advice before acid correction.

What's inside:

NPK Ratio: No NPK / pH-down regulator; 17% hydrochloric acid + 3% nitric acid in Pro listings
Nutrient basis: pH regulator - mineral acid

CANNA pH- Growth 17% Pro is a technical acidifying product for lowering pH in mixed nutrient water. It does not supply a normal feeding profile.

The composition is listed as a pH-down regulator with hydrochloric acid and nitric acid in Pro listings. Its role is precise water correction, so measurement and safe handling matter more than nutrient comparison.

How to use it

Use CANNA pH- Growth 17% Pro only after nutrients are fully mixed, then add tiny amounts while measuring pH. Stir thoroughly between adjustments so the reading reflects the whole watering solution.

Use it for lowering pH in technical nutrient water, not as part of ordinary plant feeding.

➜ A few notes before measuring, mixing or applying :

Treat this as a corrosive technical product, not a casual plant-care liquid. Wear suitable protection, add it only to already diluted nutrient water, and keep it away from children, pets and unlabelled bottles.

Store it separately from pH-up products, undiluted nutrients and metal-sensitive surfaces. Spills or skin contact need careful handling.

Frequently Asked Questions about CANNA pH- Growth 17% Pro

What is CANNA pH- Growth 17% Pro used for?

It lowers the pH of finished nutrient water. It is a technical pH-down product, not a fertilizer, booster or normal plant food.

Do normal soil-grown houseplants need CANNA pH- Growth?

Usually not. For typical soil-grown houseplants, check watering, substrate and fertilizer strength before reaching for pH correction.

How do I use CANNA pH- Growth safely?

Mix the nutrients first, then add tiny amounts while measuring pH. Never add it to another concentrate, and handle it as a strong acidifying product.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

The plants have arrived in perfect condition, the roots and the foliage so so healthy! I had problem with 1 plant out of 16 and they have responded to my email almost instantly and the issue was resolved straight away. I'm really impressed and satisfied, definitely getting more plants from them again!

I received perfectly heathy and absolutely beautiful plants, even bigger than expected. The delivery within Europe was really fast. I think Foliage Factory has one of the best plant web shops in the internet. It‘s just great to get so much informations about the plants. I will definitely order again :)
