CANNA pH Plus 1L 5%: label-led use

CANNA pH Plus 5% is used where a nutrient solution measures too acidic and needs a careful upward correction. The weaker 5% version is suited to smaller adjustments with repeated measuring.

Key details

Function: raises pH in nutrient water
Formula notes: contains potassium carbonate, 5% potassium hydroxide and declared 13% K2O
Use phase: suitable in growth and flowering solutions
Control: add tiny amounts, stir, then measure again

Correct slowly

Work with protective handling, add only very small amounts to the tank, stir thoroughly and re-test before adding more. Use the target pH for your nutrient schedule; pH around 6.2 is a common reference for mixed nutrient solutions.

CANNA pH Plus 1L 5% – controlled upward pH correction

CANNA pH Plus 5% is used to raise pH in nutrient solutions when measurements show the solution is too acidic. The 5% version is suited to smaller, more controlled adjustments.

Formula notes include potassium carbonate, 5% potassium hydroxide and a declared 13% K₂O.

Setup and use

Measure pH first, then add a small amount, mix thoroughly and re-test before adjusting again.
Work in clean containers and avoid guessing; stable pH comes from repeated measuring, not a single large correction.
Handle with care and keep away from children and pets; follow label safety guidance.

System notes

pH management is system-dependent. Always follow the nutrient brand’s target ranges and your chosen growing method.

Using it indoors

Use as directed on the label and dose to current growth. Start at the lower end of the range after repotting or during low-light periods, then adjust based on response.

If you grow in inert or mineral substrates, follow the brand’s guidance for that setup and avoid stacking multiple feeds at once.

Quick notes

Mix fresh each time and avoid storing diluted solution.
Rinse the pot occasionally with plain water if salts build up.
Store tightly closed and out of reach of children and pets.

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 :)
