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.

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.

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.

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!
