What we make, and why

Grow beyond the limits of soil. Hydroponics brings water and nutrients directly to plant roots, opening up new ways to grow leafy greens, herbs and fruiting crops—even where garden space is limited. Recirculating systems can reuse water, while measured feeding puts more of the growing process in your hands.

Nana Organics makes MICRO, GROW and BLOOM: one South African three-part nutrient system with a clear purpose for every bottle. Our focus is practical confidence—understand what you are feeding, measure it consistently and build a growing routine you can follow. Clear nutrient declarations, straightforward directions and useful tools put substance behind the brand.

Soil-free growing lets you monitor the water reaching your roots and make informed decisions about your setup. From compact towers to larger reservoirs, the right system can make productive use of available space. Light, water quality and good management still matter.

Explore the three-part set Plan your nutrient mix

The three-part system

The bottles are complementary parts, not alternatives for different growth stages. Add MICRO to water first and mix, then add GROW and mix, then BLOOM. Use 3+3+3 mL/L and maintain hydroponic tank pH at 5.5–6.0. Never mix undiluted concentrates.

MICRO
Part 1

NPK 4-0-1.5 with 4.4% calcium and micronutrients. Add first; use with GROW and BLOOM.

GROW
Part 2

NPK 3-1.5-7 with 0.8% magnesium. Supplies nitrogen, potassium, phosphorus, magnesium and sulphur. Use with MICRO and BLOOM throughout the cycle.

BLOOM
Part 3

NPK 0-5-6 with 0.9% magnesium. Use with MICRO and GROW throughout the cycle.

A practical starting point for hydroponic growing

Begin with crop, water and space

Hydroponics delivers mineral nutrients through water without soil. Plants still need suitable light, root-zone oxygen, hygiene and ongoing care. Choose a crop for your climate and time available, assess water quality and start with an observed trial rather than assuming a larger installation guarantees yield.

MICRO, GROW and BLOOM are one complementary system. Product pages describe each part; the 360° pages show illustrative packaging and nutrient declarations. Systems are complementary hardware by quotation. Crop guides and diagnostics provide cultivation context, not validated Nana Organics performance claims.

Understand your source water and readings

Source water already contains dissolved substances. Its pH, electrical conductivity (EC) and alkalinity describe different things: pH measures acidity or alkalinity at that moment, EC indicates overall dissolved-ion concentration, and alkalinity helps explain resistance to pH adjustment. A high pH alone does not identify the substances in the water. Water analysis is particularly useful when a reservoir repeatedly drifts or plants develop persistent symptoms.

Measure water before mixing and the solution afterwards with calibrated meters. EC cannot confirm individual nutrient concentrations, the bottle ratio or an independent nutrient assay. Crop EC references are not guaranteed outcomes of the Nana Organics dose. Check your measurements and request crop-specific advice if the mixed solution is unsuitable. Record readings at a consistent time and note water additions, weather and irrigation changes alongside them.
