A fully water-soluble powder fertiliser developed specifically for orchids watered with rainwater, RO or soft water.
Water-soluble fertiliser for orchids
Rain Mix® 400gr
For a larger orchid collection or frequent use, Rain Mix® 400gr provides the same complete, water-soluble nutrition in a larger size. The urea-free formula combines NPK 11.8-2.7-13.7 with calcium, magnesium, sulphur and a full range of trace elements, works with rainwater, RO or soft water and keeps feeding simple at every watering throughout the year.

800 LSolution from one pack
Balanced nutrition for one consistent feeding routine
The 11.8-2.7-13.7 analysis is combined with calcium and magnesium, helping turn low-mineral water into a more complete nutrient solution for orchids. Its low phosphorus level and absence of urea allow one formula to support both growth and flowering.
- Without urea: nitrogen is supplied without urea, matching the specific feeding approach behind this orchid formula.
- Calcium and magnesium: includes 11.8% CaO and 3.5% MgO for more complete nutrition of roots and foliage.
- Low phosphorus: 2.7% P₂O₅ supplies phosphorus without relying on an unnecessarily high level for flowering.
- Complete trace elements: contains Fe, Mn, Zn, Cu, B, Mo and Co for a comprehensive feeding programme.
One formula all year
There is no need to keep switching between grow and bloom feeds; Rain Mix® is used regardless of the orchid's current stage.
Designed for the right water
Added calcium, magnesium and trace elements make the formula particularly practical when you use rainwater, RO or soft water.
Larger pack, high output
At 0.5 g per litre, the 400gr pack makes 800 litres of solution, ideal when you care for many orchids or feed frequently.
For collections that need a larger amount
Rain Mix® 400gr keeps the same clear feeding routine, with an output that suits more orchids and more frequent watering.
Larger orchid collections
For growers caring for several plants who want one shared formula with a consistent application rate.
Frequent watering with RO or rainwater
The 400gr quantity reduces the need to replace the pack frequently.
Growth and flowering
Used throughout the year without switching between separate grow and bloom formulas.
Different species and hybrids
One shared, measurable rate simplifies feeding across a varied orchid collection.
0.5 g in every 1 litre of water
The larger pack does not change the rate: dissolve 0.5 g of product per litre and use the solution at every watering. The included 1 g measure treats 2 litres of water.
- 0.5 g / 1 L water
- At every watering
- 1 g for 2 L
- Rain · RO · soft water
- All year
Use 0.5 g for every 1 litre of water. One full 1 g measure makes 2 litres of solution.
Add the product to rainwater, RO or soft water and mix until it has completely dissolved.
Use it for normal watering, wetting the growing medium evenly and allowing excess water to drain away.
At the recommended rate and with suitable water, an additional plain-water application between feeds is not required.
The water is part of correct use
This formula is designed for rainwater, RO or soft tap water. Do not increase the rate or assume that hard, mineral-rich water is equivalent; always follow the product label.
Two sizes, the same exact rate
At 0.5 g per litre, you can choose the pack size that matches the number of orchids you grow and how often you water.
140gr280 Lprepared solution
400gr800 Lprepared solution
Calculation basis: 140 g ÷ 0.5 g/L = 280 L and 400 g ÷ 0.5 g/L = 800 L.
Available pack sizes
400gr for 800 L of solution
A larger size for an extensive collection or frequent use. It includes a 1 g measure, while the smaller 140gr pack is available separately for more limited needs.
