Product foundation
A fully water-soluble powder fertiliser developed specifically for orchids watered with rainwater, RO or soft water.
Water-soluble fertiliser for orchids
Rain Mix® 140gr
If you want one consistent, complete solution for feeding your orchids throughout the year, Rain Mix® combines nitrogen, phosphorus and potassium with calcium, magnesium, sulphur and a full range of trace elements. The urea-free, water-soluble formula is designed for rainwater, RO or soft water and uses the same simple rate at every watering, whether the plant is growing or flowering.

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.
Small dose, high output
At 0.5 g per litre, the 140gr pack makes 280 litres of solution and comfortably suits a small or medium orchid collection.
For simple, consistent care of your collection
Rain Mix® suits growers who want one clear feeding routine without changing formula according to the season or the plant's growth stage.
Orchids in active growth
For a steady supply of core nutrients, calcium, magnesium and trace elements as new roots and leaves develop.
Before and during flowering
The same balanced formula continues without switching to a separate bloom fertiliser.
Collections with different orchids
One shared, measurable rate simplifies care when you grow more than one species or hybrid.
Watering with low-mineral water
A suitable choice when you use rainwater, reverse-osmosis water or soft tap water.
0.5 g in every 1 litre of water
The rate stays simple: 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, keeping calculations straightforward.

- 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.
