🥬 Plants & seeds
Strawberries and berries in a tower
Sweet strawberries from your own living room? In a hydroponic tower it is entirely doable. We cover variety choice, EC and pH for fruiting, hand pollination and every trick for a generous harvest year-round.
🥬 Plants & seeds
Growing salads and leafy greens in a tower
Lettuce is the queen of the hydroponic tower: fast, rewarding and undemanding. We take you from seed to crisp head—EC, pH, spacing, cut-and-come-again, and how to stop premature bolting.
💡 Light & environment
LED grow lighting: spectrum, PPFD and photoperiod
Light is food for a plant. Learn what spectrum, PPFD, DLI and photoperiod really mean, and exactly how much light your lettuce, herbs and fruiting crops need to thrive.

Pests and diseases in hydroponics (organic protection / IPM)
How to identify and control aphids, spider mites, thrips, fungus gnats and whitefly, plus powdery mildew and grey mould – using integrated pest management (IPM) and the least-toxic organic remedies.
💧 Nutrients & water
Nutrient deficiency symptoms and how to spot them
Learn to read a leaf like an instrument: where a symptom appears, what the colour means, and how to tell a real deficiency from a pH problem. With a per-element symptom table.
🛠️ Maintenance & troubleshooting
Cleaning, maintaining the tower and preventing algae
A practical guide to cleaning your hydroponic tower, resetting the reservoir, safe sanitising with hydrogen peroxide, and preventing algae, biofilm and root rot.
🥬 Plants & seeds
Flowers and ornamental plants in hydroponics
Hydroponics isn't only for lettuce and herbs — a tower can bloom. Petunias, marigolds, begonias and nasturtiums bring colour indoors all year. Learn how much light they need, which EC and pH they like, and how to coax abundant flowering.
🥬 Plants & seeds
Herbs in hydroponics (basil, parsley, mint…)
Fresh basil, parsley and mint within arm's reach, all year round. We cover germination, EC and pH per herb, pinching for bushiness, and a harvest that returns week after week.

Hydroponics vs. soil growing
Faster growth and less water versus forgiving, cheap soil. An honest comparison of pros and cons, plus the flavour and health myth.
💧 Nutrients & water
How to mix and dose liquid nutrients
Step by step to a perfect solution: mixing order, the A-then-B rule, a per-crop dosing table, and the most common mistakes to avoid.
💡 Light & environment
Temperature, humidity and airflow
Light and nutrients are only half the story; the climate around the plant is the other half. Learn the ideal ranges for temperature, humidity and airflow, plus the basics of VPD.
💡 Light & environment
Growing without natural light (basements and apartments)
No sunlight? No problem. A practical guide to growing lettuce and herbs in a basement, pantry or north-facing flat - from choosing a lamp to managing humidity, air and heat.
