About Liquid Gold Leaf

The world’s only liquid fertiliser to contain every essential plant nutrient

Liquid Gold Leaf is a revolutionary and innovative liquid fertiliser for all plants and crops. The technical advance is the inclusion of fully soluble calcium, formerly too difficult and expensive for liquid fertiliser. The current best selling liquid fertilisers do not have calcium on their list of ingredients, yet it is essential for healthy plant growth.


The formulation of Liquid Gold Leaf includes plant biostimulants, which have many roles in plant health and vigour. Biostimulants: reduces fertiliser requirements; help to make immobile nutrients, e.g. calcium, to flow around the plant for optimum nutrition; stimulate the plant’s self defence mechanisms for reduced need to apply chemical pesticides. Liquid Gold Leaf optimises plant health and growth.

Liquid Gold Leaf contains Biorational ingredients, i.e. materials that only have a positive effect on the environment. There is no message of “Less harmful” or “Reduced risk of environmental damage”. Liquid Gold Leaf has only positive benefits when used according to instructions.

Growing Plants For Food With Liquid Gold Leaf

Value to the Gardener


Increase in yield due to optimised nutrition of crop.

Fewer applications of chemicals, as all nutrition delivered in one product. Saves fuel, time, labour and water. Fewer applications also minimise associated damage to soil and crops from machinery.

No need for tank mixing different fertilisers;

No risk of downtime due to nozzle blockages that result from mixing incompatible fertilisers

No time lost due to tan mixing or need to conduct ‘bucket test’ 24h before mixing

Fewer fertilisers required to be purchased; economies of scale when purchasing.Less equipment required in hydroponics, such as seperate mixing tanks, pH Meters, EC Meters & Dosatrons.

Less training for staff, as system has been massively simplified


By applying a complete fertiliser, you remove the risk that the crop will be deficient in a specific nutrient.

Just as farmers rarely spray pesticides to prevent a single specific pest/disease, they are even less likely to spray to address one specific nutrient deficiency.

Micronutrient deficiencies are almost impossible to correct once the symptoms are visible. As a result, a complete fertiliser acts pre-emptively to address issues.

Removes the risk of ‘hidden hunger’ i.e. nutrient deficiencies that are at levels that do not result in symptoms but do impact yield.


Increased shelf life, due to stronger cell walls (calcium pectin)

Higher quality class of produce, due to fewer physiological skin disorders due to calcium deficiency

Reduced damage from fungal diseases as fewer applications of different fertilisers creates a lower humidity around foliage.


Hydroponics and Liquid Gold Leaf

The world of amateur hydroponics can be a confusing place if you are not an experienced horticulturist. If you go into any grow shop or browse an online hydroponic store you will find an almost endless array of products on offer. This is especially true for the fertilisers on offer, which often have crazy outlandish names.

It is also rarely explained what is in the bottles or how to use all these different products. Then there are multiple offerings from lots of different producers.


To get started with even the most basic hydroponic system you would need to purchase the following resources just to meet the nutritional requirements of the plants:

A Fertiliser £6.00/L
B Fertiliser £6.00/L
Acid £10/L and bases £10/L
Pipettes, measuring cylinders, and beakers for measuring each separate ingredient £30
pH meter £160-300 and buffer solution £6
EC meter £40

So, faced with a bill of over £250, this represents a significant barrier to entry for anybody, especially those just wanting to dip their toe in the water and dabble with hydroponics.


You may also be persuaded to buy dedicated ‘grow’ and ‘bloom’ versions of each fertiliser, or to top up with feeds of specific nutrients (such as iron or magnesium), foliar fertilisers for spraying onto leaves, and finally biostimulants to get the crop growing faster. Which could easily double your fertiliser bill.

This complexity and cost is preventing many new entrants to hydroponics. It was these challenges that drove the efforts to create a completely new type of hydroponic fertiliser; one that does away with the need for all the products and equipment listed above and replaces it all with a single product. This product has been named “Liquid Gold Leaf”.


So how does Liquid Gold Leaf Do All This?

Gold Leaf supplies all essential nutrients at once. This is no easy feat, and has been the ‘holy grail’ of hydroponic fertiliser producers since the industry began in the 1970s. The reason it is usually not possible is because calcium and phosphate normally precipitate out if mixed together, hence why other hydroponic fertilisers are delivered in A and B bottles.


While you may find that there are products on the market claiming to be ‘one part’ complete fertilizers, these are often very weak (e.g. NPK = 1 : 0.3 : 3 ), or are suspensions of insoluble material. In contrast, Liquid Gold Leaf is packed with fully soluble nutrients (NPK = 9:5:16 ).

To prevent issues with pH limiting the plants ability to access nutrients Liquid Gold Leaf is already at the pH optimum for growth (6.5). Furthermore, Liquid Gold Leaf is also highly buffered meaning the fertigation liquid will not be quick to drift away from this optimum as the plants start removing nutrients and exudes acids from their roots.

A consistent formulation means that you do not necessarily need an EC meter to get the correct concentration. Just follow the simple dosage instructions on the label. A pump dispenser is included so that every dose is the same and no measuring cylinders are required for accurate dosing.

In addition to replacing the conventional A+B fertilisers, Liquid Gold Leaf is also superior in relation to the ingredients; in particular, it is not packed with chlorides, which are often far too high in most liquid fertilisers as potassium chloride is a cheap way of getting potassium into solution. Liquid Gold Leaf uses other anions to deliver potassium. Chlorides are only required by plants in tiny amounts, which are more than easily met by the ‘hardness’ found in water. Any levels above this are not of benefit and potentially detrimental to plant growth.

If you are using an EC meter, it is important to note that Liquid Gold Leaf contains no chlorides. You will therefore not want to match your usual EC level as chlorides give a very high EC value and the higher quality nutrients in Liquid Gold Leaf are not as conductive.

Liquid Gold Leaf also makes fertilising hydroponic crops safer with no need to handle dangerous acids. However, as is standard for most chemical fertilisers, the product in the concentrated form is classified as hazardous (a skin and eye irritant similar to washing up liquid) so should be handled according to the stated instructions only.

While Liquid Gold Leaf was initially designed with the home hydroponic market in mind, there is no reason why it cannot also be used in the commercial sector. It would be a great option for fertilising crops in growth rooms where space is limited and where dedicated A and B holding tanks are not ideal as they take up a significant amount of the space that could be used to grow crops. Such scenarios include the use of shipping containers to grow crops in urban areas.

In addition to being the only concentrated complete hydroponic fertiliser, Liquid Gold Leaf also has a unique colour and appearance. It also produces an intriguing ‘Pernod’ style cloud as it goes into solution.
