Explore the range →Why Holiplants
Too many brands sell mystery bottles. Holiplants was born from a simple frustration: wanting to know exactly what you're feeding your plants — and why.
The Problem
Over-dosed products, vague labels, ranges with 10 bottles. We wanted the opposite: a minimal, transparent system that works. With Swiss-watch precision. No fillers. No chloride. Just what your plants need — nothing more, nothing less.
For Whom
You measure your EC, you monitor your runoff, you want control. Holiplants is built for you — not for those buying marketing hype.
The System
Three powders + one liquid. Two phases, one transition. You swap VEG for FLOWER and that's it. Everything else stays the same.
The Origin
R&D and production in Switzerland. What you read on the label is what's inside.
The 4 Components
Three macro-element powders and one trace-element liquid. Independent dosing, maximum precision.
Powder
Calcium and nitric nitrogen base. Foundation of all nutrition, present in every phase. White powder, immediate dissolution.
Available in1 kg · 5 kg · 10 kg
Powder
Multi-mineral growth. Potassium, phosphorus, magnesium and sulfur for vigorous vegetative development.
Available in1 kg · 5 kg · 10 kg
Powder
High-performance flowering. P:K ratio of 1:2 for maximum fruiting. Zero nitrogen — controlled by SOCLE.
Available in1 kg · 5 kg · 10 kg
Liquid
Complete trace-element complex. Dual-chelated iron, availability pH 3–10. Independent dosing — increasable anytime to correct deficiency immediately.

Growth
SOCLE + VEG + MICRO
Flowering
SOCLE + FLOWER + MICRO
SOCLE and MICRO are constant — only VEG ↔ FLOWER changes between phases.

Feeding Schedule
Example schedule with conservative EC values. Adjust based on genetics, substrate and growing conditions.
| Phase | Target EC | Formula | Notes |
|---|---|---|---|
| Cuttings / Clones | 0.8 – 1.0 | SOCLE + VEG | Start low. Foliar misting possible. |
| Growth — Early | 1.3 – 1.5 | SOCLE + VEG | Increase after root establishment. |
| Growth — Full | 1.5 – 2.0 | SOCLE + VEG | Main phase. Adjust per vigor and runoff. |
| Transition | 1.2 – 1.5 | SOCLE + FLOWER | VEG → FLOWER switch. Lower EC slightly. |
| Flowering — Early | 1.5 – 2.0 | SOCLE + FLOWER | Progressive increase. Flower site formation. |
| Flowering — Full | 2.0 – 2.5 | SOCLE + FLOWER | Peak demand. Monitor runoff and EC. |
| Maturation | 1.5 – 2.0 | SOCLE + FLOWER | Gradual reduction. Quality and ripeness. |
| Flush | 0 – 0.3 | Clean water | Final days. RO or tap water. |
MICRO is added in all phases except flush. Dosage: 0.22 mL per gram of SOCLE.
Preparation Guide
Dissolution: max. 200 g powder per liter of water.
Fill with desired water volume (RO or tap water).
In a bucket, dissolve the VEG or FLOWER dose (max. 200 g/L). Pour into tank, stir.
In a second bucket, dissolve the SOCLE dose (max. 200 g/L). Pour into tank, stir.
Pour the MICRO dose directly into the tank.
Stir, check EC, then adjust pH to 5.5–6.2. Above 6.2, calcium and iron risk precipitating.
Why Holiplants

Up to 31% more concentrated than comparable powder systems. Less product, same results.
02
Fe-EDDHA + Fe-DTPA: iron stability guaranteed across full pH range 3–10. No precipitation.
03
LED spectrum reduces photosynthesis and increases demand for manganese, zinc and boron. Our formulas account for it.
04
Swap VEG for FLOWER. No intermediate formulas, no complex calculations.
05
100% nitric nitrogen. Zero urea, zero ammonium in flowering formulas. Complete dissolution.
06
Independent dosing from macros. Fine adjustment per growing conditions.
07
Coco, rockwool, clay pebbles, soil. One range, no substrate variants. Nutrition stays the same — drainage is what changes.
08
No chloride in any formula. No toxic buildup, no salt stress. Compatible with sensitive crops.
09
Complete compositions available. No "proprietary complex", no hidden ingredients. You know exactly what you're using.
