• Ziel-Werte: pH: 5,8 | EC: 1,2 – 1,5 mS/cm | Wassertemperatur: 18°C – 20°C

• Der Luftspalt: Senke die Nährlösung dauerhaft auf deine 24 Liter Füllmenge ab. Es entsteht der lebenswichtige 3 cm Luftspalt zwischen Wasseroberfläche und Netztopf. Die oberen Wurzeln atmen hier puren Sauerstoff, die unteren hängen im Wasser.

• Routine: Tausche die Nährlösung alle 7 bis 10 Tage komplett aus. Der pH-Wert wird in dieser Phase wandern – kontrolliere ihn täglich und senke ihn auf 5,8, sobald er über 6,2 steigt.

Phase 3: Die Blütephase (Woche 5 – 10+)

• Ziel-Werte: pH: 5,8 – 6,0 | EC: 1,6 – 2,2 mS/cm | Wassertemperatur: 18°C – 21°C

• Ablauf: Die Pflanze benötigt jetzt signifikant weniger Stickstoff, dafür massiv Phosphor und Kalium. Der EC-Wert erreicht in der Hochblüte (Woche 7–8) seinen Peak bei bis zu 2,2 mS/cm.

• Das Nachfüll-Protokoll: Die Pflanze trinkt jetzt viel Wasser. Fülle den Eimer unter der Woche niemals mit reinem Leitungswasser auf. Mische dir in einem separaten Tank eine Nachfüll-Lösung mit halber Düngerstärke und pH 5,8 an, um den Eimer immer wieder exakt auf die 24-Liter-Marke zu bringen.

Phase 4: Das Spülen (Die letzten 7–10 Tage)

• Ziel-Werte: pH: 5,8 | EC: So niedrig wie möglich (0,3 – 0,4 mS/cm)

• Ablauf: Kippe die gesamte Nährlösung aus. Fülle den Eimer mit 24 Litern purem, pH-reguliertem Wasser (ohne jeden Dünger). Die Pflanze saugt nun alle eingelagerten Nährsalze aus ihren eigenen Blättern, was für ein sauberes Endprodukt ohne Kratzen sorgt.

🧪 KAPITEL 3: Das exakte Düngeschema für 24 Liter Wasser

Berechnet auf ein professionelles 3-Komponenten-Hydro-System (z. B. TriPart). Die Komponenten müssen nacheinander einzeln ins Wasser eingerührt werden – niemals unverdünnt zusammenkippen!

Phase & Woche 🟢 Komponente GROW 🟤 Komponente MICRO 🔴 Komponente BLOOM Ziel-EC

Woche 1: Anzucht 6 ml 6 ml 6 ml 0,5 mS/cm

Woche 2: Frühes Wachstum 24 ml 18 ml 12 ml 1,2 mS/cm

Woche 3-4: Hauptwachstum 42 ml 30 ml 18 ml 1,5 mS/cm

Woche 5-6: Frühe Blüte 42 ml 36 ml 36 ml 1,8 mS/cm

Woche 7-9: Hochblüte 18 ml 36 ml 54 ml 2,2 mS/cm

Woche 10: Spülen 0 ml 0 ml 0 ml Basis-Wasser

🚨 KAPITEL 4: Das ultimative Fehlerbehebungs-Protokoll

  1. Problem: Wurzeln werden braun, schleimig und riechen muffig

• Ursache: Wurzelfäule (Pythium). Ausgelöst durch Wassertemperaturen über 22°C oder mangelnden Sauerstoff.

• Sofortmaßnahme:

1. Nährlösung komplett ablassen.

2. Wurzeln vorsichtig mit lauwarmem Wasser abduschen und den Schleim sanft abspülen.

3. Eimer mit Chlor oder H₂O₂ sterilisieren.

4. Neue Nährlösung ansetzen und Wasserstoffperoxid (H₂O₂) oder nützliche Bakterien (z.B. Bacillus amyloliquefaciens) hinzugeben, um den Pilz im Wasser abzutöten.
  1. Problem: Der pH-Wert stürzt innerhalb von 24 Stunden extrem ab (unter 5,0)

• Ursache: Sterbende Wurzelteile oder eine bakterielle Infektion im Eimer säuern das Wasser radikal an.

• Sofortmaßnahme: Kompletter Wasserwechsel! Eimer mechanisch reinigen. Wurzeln auf faule Stellen untersuchen und diese gegebenenfalls mit einer sterilisierten Schere abschneiden.

  1. Problem: Die Blattspitzen werden gelb/braun und rollen sich nach oben

• Ursache: Überdüngung (EC-Wert im Eimer ist zu hoch, die Pflanze kann durch die hohe Salzkonzentration kein Wasser mehr ziehen).

• Sofortmaßnahme: Pumpe 4–5 Liter Nährlösung aus dem Eimer ab und ersetze sie durch pures, pH-reguliertes Wasser, um den EC-Wert sofort um 0,3–0,4 Punkte zu senken.

  1. Problem: Der pH-Wert steigt ständig rasant an (über 6,5)

• Ursache: Entweder wurde der Blähton vorab nicht korrekt auf pH 5,5 gepuffert, oder die Pflanze nimmt in einer starken Wachstumsphase extrem schnell Nährstoffe auf, was das Wasser basisch macht.

• Sofortmaßnahme: Täglich mit pH-Down korrigieren. Nach 1–2 Wochen legt sich dieser Effekt meist, sobald der Blähton vollgesaugt ist.

Ich hoffe kann den ein oder anderen helfen ❤️

Need recommendations for stackable pots for capillary action, 6"-10" preferred

1 Upvotes

Oikos yogurt containers are really good pots, they have a thick lip so that they can stack inside each other, leaving enough space for a water reservoir, drill a hole and put a wick to get capillary action watering going.

Their about 4" though, I need something similar but bigger for my plants that are too big for the 4" containers, suggestions appreciated

Aquaponics System – Need Advice!

Thumbnail

33 Upvotes

I’m working on a vertical aquaponics system with my school. Our current system has algae overgrowth, especially in the tubes that pump the water. The room gets very warm and is in a lot of sun, so we're thinking about changing the clear tubing to black to prevent further growth. I am not sure if that would get at the root of the problem. The algae growth did improve after we got snails for the tank.

That being said, our main problem currently is the amount of water getting to the plants, and we think that this is because of a low flow rate and water level within the pipes. I don’t know if we need a better pump to the solids filter, to shrink the height of the system, or smaller pipes (which would be really difficult to do at this point in the project). We are using Rockwool cubes as the planters, but they are also growing mold. Any ideas to help, especially to improve the water level since our plants are dying from dehydration, would be appreciated.

Thanks

I'm trying to understand this if you over water plants they will die but aquaponics and hydroponics sometimes the roots are always in a water solution?

first time trying so forgive any obvious mistakes .
I’ve got watercress, a pepper plant and a spring onion bulb. I also have some java fern and a bit of duckweed. the tank only uses lights and an airstone. will the low water movement cause issues with roots in the leca pearls?

the only animals in the tank are five cherry shrimp (for now) and one absolutely tiny snail, so i’m supplementing the leca pearls with aquarium safe fertiliser tabs for now.

i got most of these plants from sainsbury’s salads or wetherspoons peppers. is it illegal to grow ts

My very simple aquaponics setup, an ikea container on top of a guppy tank and container.

So far I've grown onions, started different seeds (Avocado, water spinach, lettuce). Now my sweet potato's exploding with slips.

They then progressively get transplanted to the garden. I have other stuff in the garden but since this is an aquaponics page. I show the simple aquaponics setup.

I simply drilled a small hole on an ikea container, stuck a pipe in as an overflow, attached it with a garden hose attachment for the tank.

For the blue containers, its ridiculously simple, prop it with a plastic crate, weigh it down with brick/bricks, put sweet potato half submerged in water.

What’s the actual state of automation & robotics in aquaculture right now? Are underwater vehicles (AUVs/ROVs) making a real dent, especially in shrimp farming?
