How to use your My Greens
Hydroponic Products

Thanks for shopping with My Greens Hydroponics, and for supporting a small NZ-made business. Here are some quick guides on growing with our growing mediums, nutrients and measuring tools. If you have any further questions, please get in touch.

HOW TO:

Mix your Nutrients

These instructions are for mixing Nutrients into My Greens Jerry Cans, but you may substitute this for a clean bucket >7L with a lid. Don't mix Part A and Part B together in the same container.

Take your Part A Jerry Can and fill it with 7L of normal tap water. Add your powdered Part A Nutrient mix into the Jerry Can, secure the lid and shake to dissolve the powder.

Take your Part B Jerry Can and fill it with 7L of normal tap water. Add your powdered Part B Nutrient mix into the Jerry Can water as well as your Part C brown trace element bag, secure the lid and shake to dissolve the powder.

Let them rest, then shake again to completely dissolve the mix. Once completed, lay them down bung side up, remove the bungs and secure the taps.

HOW TO:

Calibrate your pH Pen

Open your Bluelab pH Pen and follow the calibration instructions on the box.

Once this is done, use your pH Pen to measure the pH reading of your water reservoir. A range of 5.5-6.5pH is commonly used for a mixed crop. Ratio to use: 1/2 capful per 70L. Remeasure using your pH pen and adjust again if necessary to reach the desired range.

If needed, pH Upper solution can be made with one teaspoon of Baking Soda, mixed into one cup of water. Use sparingly.

NOTE: Undiluted pH Lower can mark surfaces and cause irritation on skin. Use carefully.

HOW TO:

Use your EC Pen

This Pen comes pre-calibrated. Turn it on and place the probe into your water reservoir. For a mixed crop of seeds and small seedlings, a measurement of between 1.2-1.6 is a good starting point until they are about mid-sized plants.

HOW TO:

Use pH Lower

Use your pH Pen to measure the pH reading of your water reservoir. A range of 5.5-6.5pH is commonly used for a mixed crop. Ratio to use: 1/2 capful per 70L. Remeasure using your pH pen and adjust again if necessary to reach the desired range.

If needed, pH Upper solution can be made with one teaspoon of Baking Soda, mixed into one cup of water. Use sparingly.

HOW TO:

Use Stonewool and Vermiculite/Perlite

These growing mediums help to stabalise your plant as it grows, retain moisture as well as prevent sunlight from getting into your gullies which can cause algae to grow. Use the guide below for growing from either seed or seedling.
