Buddha’s Tree hydroponic additives have taken the UK hydroponics shelves by storm, and for good reason! Buddhas Tree’s range of powerful nutrient additives and boosters have given growers in the know the edge over their competition for years now, with many followers crying out for a suitable base nutrient to complete the line-up. Building on the huge success of the additives range, Buddhas Tree have formulated an entirely unique base nutrient line, specifically for growers using coco coir as a substrate. Making the perfect addition to your existing Buddhas Tree additive range, Coco A-B makes growing beautiful plants, effortless.

Buddhas Tree Coco A-B is entirely suited to growing with coco coir, in any modern-day drip system. It’s whistle-clean formulation means that no residues or blockages will form in any hydroponic irrigation system you use, because of the fertiliser itself. Offering huge flexibility to the grower while maintaining a powerfully effective combination of essential plant nutrients, Buddhas Tree Coco A-B really sets the standard high when it comes to hydroponic base nutrients.


At it's heart, Coco A-B is a complete hydroponic fertiliser for use with coco coir, providing all the essential macro and micro nutrients throughout a plant’s entire life cycle. It is a two-part nutrient, to be used at increasing levels as your plant grows and develops large fruits and flowers. The level of calcium needed to ensure a correct cation exchange rate has been suitably refined in these bottles, meaning the chance of nutrient lockout is reduced to a minimum, either through the Cation Exchange Capacity of the coir itself, or through unwanted antagonism between nutrient elements.

One complete A & B – By making use of the fundamental nature of coco coir itself, Buddhas Tree Coco A-B does not need separate ’Grow’ and ‘Bloom’ nutrients. The fibres in the coco will naturally want to take the calcium out of the nutrient solution and replace them with potassium. By ensuring an appropriate level of calcium in the nutrient solution, you can ensure the calcium and potassium exchange is at the correct rate, throughout an entire grow. Due to its concentrated nature, the nutrient must be split into two bottles, with the calcium present in the ‘A’ and the phosphorous is in the ‘B’. This allows a high concentration of nutrients while avoiding any of the associated problems with forming substances like Gypsum.

Fully chelated – A chelate is protection for certain nutrients. Basically, it is a layer of armour around an element keeping it nice and safe until the plant needs it. For example, Iron is a micro nutrient that plants continually make use of and constantly need available in a nutrient solution for healthy growth. Unfortunately, Iron tends to rust when you put it in water, a bit annoying when you want your plant to use it! A chelate surrounds the iron molecule, protecting it from the surrounding environment so it doesn’t rust and become useless. Chelates comes in many shapes and forms, Buddhas Tree use only cutting-edge inputs to ensure maximum availability of nutrient, over a wide range of pH levels.


Coco A-B hydroponic nutrient from Buddhas Tree, that is extremely easy to use at virtually any stage of growth. Begin from after they have been potted in to their first pot, use Buddhas Tree Coco A-B at around the half strength rate. This means using 2ml of part A and 2ml of part B for every Litre of your total nutrient solution. As your plants grow, you need to gently increase this up to the maximum rate of 4ml per Litre when your plant is growing at its most vigorous. Increase the dose gently throughout its lifecycle to avoid any unwanted nutrient shock to the plant’s roots.

Cation Exchange – As the strength of the nutrient solution is increased throughout the growth cycle and up to its maximum during the flowering cycle, the rate of potassium release increases in the substrate as the overall EC rises. When higher EC levels are reached during the flowering period, high levels of potassium are released naturally into the available nutrient solution, meaning that simply by watering with the correct strength of nutrients, you are creating the ideal flowering feed inside the substrate itself.

Nutrient Ratios – The base nutrient salts used in Buddhas Tree have been carefully selected and formulated in a way to ensure that no nutrient will out compete another within the solution. An availability of one nutrient, is directly related to the amount of another present in the solution. Buddhas Tree perfectly compensate for this, ensuring that both macro nutrients (such as Nitrogen, Phosphorous etc) are available, as well as crucial micro nutrients (like Iron, Magnesium etc). Nutrient management has never been so easy.

pH Balanced – As mentioned, certain elements need to be chelated to protect them from reacting and becoming unavailable to the plant. The chelate forms a protective layer around the element. Chelates come in many forms, being suitable for different pH ranges. The chelates used in Buddhas Tree Coco A-B mean all the elements are available over a wide range of pH levels, and require minimal energy from the plant to release.


Always ensure that you refer to the feeding schedule as provided by Buddhas Tree, while keeping a close eye on how your plants are responding. Variations in environmental conditions will always impact on how much nutrient your plant uses, so make sure you use the feed chart as a guide, and listen to your plant as well!

Buddhas Tree Coco A-B start at a concentration of around 2ml per litre of water. Throughout the plants life, you will slowly increase this up to a maximum of 4ml per litre as it is required. Depending on the additives that you choose to use alongside the A&B, you may need to compensate the dose. Further details of this can be found here on the feed schedule for Buddhas Tree Coco A-B.

Instead of simply dosing by the ml per Litre recommendations on the bottle, you make use of an EC meter and become extremely accurate with what your plant needs. Measuring the strength of the reservoir, compared to the strength of the run-off will give a good indication of how your plant is feeding. Jumps or falls in EC strength between the two will indicate whether you need to increase or reduce the strength of each feed.

Always ensure that you pH check the nutrient solution after adding all your nutrients and additives. While Buddhas Tree is well chelated, it is always best practice to keep your pH within the range of 5.5 to 6.2 when using Coco as a media. During the vegetative stage keeping to the lower end of the scale, and then slowly moving to the higher end of the scale when transitioning into the flowering cycle. This will compensate for the natural tendency of the pH to rise during veg and drop during flower.


Add equal parts of the A and B nutrient, separately, to your water. Never combine the nutrients together in their concentrated form!

Always shake the bottle well before use!

Always store in a cool dry place. This will ensure maximum performance and a long shelf life.
