Hydroponics starter fertiliser kit, 3 x 500 ml
This kit brings together a complete fertiliser for each growth stage: a growth fertiliser NPK 7-4-10, a flowering fertiliser NPK 4-8-7, and an end-of-flowering fertiliser with no nitrogen NPK 0-6-5, each in a 500 ml bottle, along with a sachet of 25 g of pH- powder.
A single fertiliser is sufficient at each stage; the two NovaMax are only combined during pre-flowering, at 1 ml per litre each. The kit is suitable for hydroponics, coco fibre, and soil.
The summary
- What you receive: grow, bloom, and late-bloom fertilisers in 500 ml, plus 25 g of pH- powder.
- How it works: a single bottle per phase, with no mixing of parts A and B and no calcium supplement required.
- What it covers: approximately 330 litres of solution during the grow phase and 200 litres during flowering.
- Safety: the pH- and both NovaMax fertilisers should be handled with gloves and safety glasses.
Three 500 ml mineral fertilisers, one per growth stage, and a sachet of pH- for a complete first crop
A first attempt at soilless growing often comes unstuck at the nutrient solution stage: two or three bottles to measure out in the right order, a calcium and magnesium supplement, then ratios that shift at every growth stage. This kit removes that step entirely. It contains one complete fertiliser per phase, NovaMax Grow for vegetative growth, NovaMax Bloom for flowering, and FinalPart for ripening, so you add just one product per phase to your reservoir. The only exception is the short pre-flowering window, where both NovaMax solutions share the mix, before you correct the pH using the sachet included.
🧪 One bottle per phase
Each of the two NovaMax fertilisers is formulated as a single, highly concentrated part containing nitrogen, phosphorus, potassium, calcium, magnesium, sulphur and chelated trace elements. Dosing is measured in millilitres per litre of water, and the maximum dose of 2.5 ml per litre is the same for both bottles. The third bottle follows a different logic: it contains no nitrogen and replaces the flowering fertiliser during the final days of the cycle.
Growth, NPK 7-4-10
From 0.3 ml per litre at first root emergence to 1.5 ml at full growth.
Flowering, NPK 4-8-7
1 ml of each NovaMax in pre-flowering, then 2.5 ml of the bloom formula alone.
Maturation, NPK 0-6-5
5 ml per litre, used alone, during the final 10 to 15 days.
Measure the pH before adding the powder
The pH- sachet corrects the solution, but it does not tell you by how much it needs to drop, and both NovaMax fertilisers are already acidic. The liquid pH test gives you the value after adding the fertiliser, which avoids adding acid unnecessarily. Adjust in small increments, aiming for 5.5 to 6.5 during growth and 6.4 to 6.8 with the flowering fertiliser, and keep the test kit for future grows.
Handle powder and concentrates wearing gloves and goggles
The powdered pH- is urea phosphate, which forms a highly acidic solution when dissolved and causes severe burns to skin and eyes. Both NovaMax fertilisers cause serious eye damage and may intensify a fire. Wear gloves and goggles, always dissolve the powder in water and never the other way round, and store the kit out of reach of children.
pH- is prepared separately: dissolve 1 g of powder in 5 to 6 litres of water, then pour this acidic solution into the reservoir, already enriched with fertiliser, in small amounts, measuring between each addition. A 25 g sachet prepares 125 to 150 litres of this acidic solution, of which each correction uses only a portion, the more so the harder your water is. Beyond that point, the 250 g tub of pH- powder takes over.
This programme is suited to hydroponic systems, pots filled with coco fibre or clay pebbles, and soil growing, with slightly lower doses in soil. NovaMax fertilisers come in a single version for all water types. If your tap water exceeds 70 mg of calcium per litre, a fertiliser available in a hard-water version allows finer calcium adjustment, such as the three-part kit.
📅 A complete tomato cycle
Take four tomato plants on a small 40-litre flood-and-drain table. During the 4 to 6 weeks of growth, make up the solution at 1.5 ml of NovaMax Grow per litre, that is 60 ml per reservoir. At the first flower buds, switch to 40 ml of each NovaMax fertiliser for 1 to 2 weeks, then to 100 ml of NovaMax Bloom alone. During the final 10 days, the solution moves to 200 ml of FinalPart with nothing else added, and the plant completes fruit ripening by drawing on its nitrogen reserves.
📊 Volume prepared by each bottle
At its full growth dose, the NovaMax Grow bottle makes up around 330 litres of solution, the NovaMax Bloom bottle around 200 litres at 2.5 ml per litre, and the FinalPart bottle 100 litres at 5 ml per litre. For a 40-litre reservoir changed every week, that gives you roughly 8 weeks of growth and 5 weeks of flowering, which is enough to cover a first fruiting-vegetable crop. The end-of-flowering bottle is the first to run out, and you can also find it as a 1 L bottle.
🔒 Store fertilisers and powder safely
Stored upright with caps screwed on, between 5 and 35 °C and out of direct sunlight, the three liquid fertilisers keep for 5 years after opening, shake them before each use, as a sediment may form at the bottom. The pH- sachet should be kept tightly resealed, in a dry place and locked away, as it remains corrosive. The set measures 23 x 16.9 x 7.7 cm and weighs 2.1 kg, making it less expensive than buying the three bottles and the sachet separately.
