Here we will address commonly asked questions about using MANTIS™ Buffered Nutrients. If you have any specific questions please email us at and we will get back to you as soon as we can.

The design of our pH buffer makes colorimetric pH testing difficult. We recommend a digital calibrated pH meter (potentiometric pH testing) for more accurate results.

MANTIS™ works great with organic substrates. Because the substrate is also a source of nutrients we suggest you only use MANTIS™ every second time you water.

RO water can have unstable polarity after the ions have been stripped away. Our buffer tries to fix this issue first before controlling the pH of our nutrient solution, making the final pH for your plants less than desirable.

You can but you don’t need to. We designed MANTIS™ Buffered Nutrients to be the complete package for growing premium quality cannabis.

Again, you can but you don’t need to. MANTIS™ is made to be used at 5 mL per L of water throughout the entire life cycle to allow for optimal uptake at important stages of plant development.

See above :)

Our super concentrated formulation needs to be shaken well to be fully re-suspended before use to make sure you get the same amounts of components each time you apply.

We keep the concentration relatively low at 5 mL per L of water throughout the plant’s life cycle. This prevents salt build ups that traditionally require flushing.

Absolutely! We recommend that you keep the solution agitated to insure that all components are equally distributed, keeping the pH and nutrient rate as designed.

You can add other products when using MANTIS™ but we don’t recommend it. MANTIS™ is made to be all you need. :)
