Our liquid NPK nutrients for herbs and leafy greens is the ideal solution for the home grower's hydroponic system. All of our nutrients are NPK Fertiliser (nitrogen, phosphate, potassium among other nutrients) solutions which results in fast growth and good value.

  • Contains the essential minerals required for plants to grow.
  • pH buffered to ensure all minerals are available to the plant.
  • Easy to use
  • Makes 200L of solution per litre of nutrient.

Why do our larger packs come in Part A and Part B sachets?

When calcium comes into contact with some micronutrients at high concentration, they mix together and form a powder which does not dissolve (and is therefore unused by your plants!). To get around this, you can first dilute the part A nutrients with water, before then adding the part B nutrients to the diluted part A solution. This ensures maximum nutrient availability to your plants.

The single part nutrient has been stabilised to prevent this, but is therefore more expensive.

WARNING: Do not consume.

Size variants

Size What you get
Great for Litres made
200mL Comes as a single 200mL bottle with single part liquid nutrients. Beginner gardeners who want a quick and easy nutrient formula. Makes 40L of nutrient solution.
1L (2x500mL) Comes as 2x500mL sachets of liquid nutrients. Gardeners with larger hydroponic gardens such as the sun shelf or heirloom garden who are looking for better value nutrients. Makes 200L of nutrient solution.
5L (2x2500mL) Comes as 2x2.5L pouches packed with powdered nutrients. Simply add 2.5L of water to each pouch, shake thoroughly, and then add to your hydroponic basin at the dilution suggested on the pouch. Note that this is the same formula as the 1L nutrients, just in powdered form. Gardeners with BIG hydroponic systems or many different products who are looking for the best value and have space to store their nutrients. Makes 1000L of nutrient solution.

Instructions

All three size options come with instructions written on the packaging. For best results we suggest using a nutrient meter to accurately test the amount of nutrients contained in your water, and make sure your plant gets the best growth.

Micronutrients and trace elements may build up in the solution over time as some elements are used more than others. It is recommended that you empty and replace your entire solution every 3 months to avoid this build up.

How Nutrients Work

Hydroponic nutrients can sound complicated at first, but once you learn a few basic principles you can grow like a pro in your own home. Hydroponics is easy to learn, hard to master and super rewarding.

We've put together some really simple educational material to ease you into your hydroponic growing journey:

  • To get started in your hydroponic learning journey, read our blog post on what nutrients plants need to grow. If you follow the blog series that it's a part of then you should get a really good idea of how everything works.
  • When you buy a smart garden from gathera, it comes with instructions on how to use the nutrients, with rule of thumb guidelines on how much nutrients your plant needs. If you want to get the most out of your nutrients, we recommend getting a nutrient meter which can tell you exactly how much nutrient there is in the water - optimising your plant's growth.
  • To figure out how much nutrient your plant needs, you can check out our plant nutrient requirement page which can tell you the pH, and nutrient concentraton required by most plants.
  • Finally - when you start getting good, you'll want to use a pH meter and pH adjusters to optimise the pH of the nutrient solution. Having the right pH will let you access ALL of the minerals in the nutrients properly, optimising growth.

It's hard to fail with the combination of nutrients, rockwool and grow lights that we offer, but you'll notice that with each additional bit of knowledge you can get higher and higher yields - helping you get the most out of your smart garden!

How much nutrient should I add to my hydroponic garden?

Follow the dilution on your nutrient label. Herbs and leafy greens need roughly half the nutrients that fruiting and flowering plants do. As water evaporates, top up with water and nutrients at the same dilution.

For the most accurate results, test with a nutrient meter and check your plant against our plant nutrient chart.

What pH and EC levels do my plants need?

Most herbs and leafy greens grow well at a pH of 5.5 to 6.5 and an EC of 1.0 to 2.0. Every plant is a little different, so look yours up in our plant nutrient chart.

If EC is too high, dilute with plain water. If it is too low, add more nutrient solution. A pH meter helps you confirm your solution is in range.

Why are my plant's leaves yellow, drooping or crispy?

  • Yellow leaves often mean the nutrient balance is off. Drain the basin, refill with plain water for a week or two, then reintroduce nutrients.
  • Drooping leaves usually point to temperature or water. Check all roots are in water and move the plant somewhere cooler or with better airflow.
  • Crispy leaves are usually too much light. Lower the brightness, raise the light or shorten the timer.
  • Thin, sparse growth can mean a young plant that needs time, or a plant that needs more nutrients.

Why is my plant growing so slowly?

The four most common reasons:

  • Its natural cycle. Days to maturity usually count from germination, which can add a few weeks.
  • Not enough nutrients or light.
  • Over-pruning, which leaves too few leaves for photosynthesis.
  • Cold or still air. Many plants prefer the mid-20s Celsius and gentle airflow.

See our tips on how to make hydroponic plants grow fast.

How often should I replace my nutrient solution?

We recommend emptying and replacing the whole solution every 3 months. Some trace elements build up over time as plants use certain nutrients faster than others. Read more in what nutrients do plants need?

Is food grown hydroponically safe to eat?

Yes. Hydroponic nutrients provide the same minerals plants take from soil, and growing indoors without soil avoids soil-borne contaminants, pesticides and herbicides. As with any fresh produce, give it a rinse under cold water before eating.

This saved my hydroponic tomato plant.

My tomato plant showing signs of malnutrition with patchy looking leaves in my Mr. Frothergills Hydrogarden Elite & I put 3 squirts of the Gathera nutrition into the system & now the plant looks so much better & it's actually started flowering! I'm pretty happy with that result & the plant nutrition from Gathera is simple to use without having to mix it up beforehand.

We're thrilled to hear that our hydroponic nutrients helped bring your tomato plant back to life and even got it flowering! ✨ Hydroponics should be simple and effective, and we’re so glad you found our nutrients easy to use.

Excellent

These nutrients have been so wonderful. My lettuces grow amazingly well, I haven’t had to buy lettuce in a year! In the middle of summer it only takes 4 weeks to be picking lettuce from the day I plant seeds. Basil and dill love it, as well as my Silverbeet. Im picking Silverbeet every few days to a week. My seedlings as both tomatoes and capsicums have grown so much faster, stronger and healthier in my EcoKitchen with these nutrients than the ones I planted in soil. They happily transfer to soil when they have reached the top of my EcoKitchen. It’s honestly amazing. I have actually started feeding it to my monstera and it’s just produced a new leaf!

Delivery issues

The product was not delivered by Aus Post due to damage and was being returned to sender. Hopefully when received it will be replaced and packed to survive transport given it has been paid for.

Happy plants.

Works well, the plants grow well with it. I buy the one litre which comes in a refill bag, not a bottle. It does state on the bag that they can be recycled by sending back using the enclosed envelope and they will reuse them. I love that concept, yet despite having done multiple orders and personally contacting them-I’ve not once received an envelope so they end up in landfill. Great concept, poor execution-disappointing.

Great liquid fertiliser

I previously used the granular fertiliser but have changed to the liquid version this time. This liquid fertiliser is easy to use. Just add to water and it’s ready immediately to top up my urban plant growers eco kitchen hydroponic garden. The seedlings are looking healthy and green. Very happy with this product.
