Plantan in English

Practical growing advice for Icelandic conditions, from choosing indoor crops and caring for roots to nutrition, lighting and pump-free hydroponics. These guides bring Plantan’s Icelandic articles and first-hand growing experience to English-speaking readers.

A fertiliser bag labelled 20–20–20 and cards showing 20% P₂O₅ converted to 8.72% P and 20% K₂O converted to 16.60% K.

Oxide equivalents or elements?

Four bowls of coir, clay pebbles, stone-wool cubes and white perlite on a workbench.

Growing media: what should surround the roots?

Scales, measuring cylinders and fertiliser in powder, granule and liquid forms on a sunlit greenhouse workbench.

Plant nutrition

A hydroponic plant under coloured light in the evening; UV and IR are marked outside the visible spectrum.

Lighting

A pH meter with its probe in a clear solution shows pH 6.0, beside a colour scale from 0 to 14.

pH (acidity)

Basil, lettuce, microgreens and a pepper plant on a bright worktop beside a window.

What is good to grow indoors?

A basil root ball rests on a tray beside an empty pot; pale branching roots are visible in the growing medium.

Healthy roots

Lettuce in a net pot above a nutrient solution; a cutaway in the Kratky reservoir shows the air gap and roots reaching into the water.

The Kratky method: hydroponics without a pump

A submersible pump in a transparent demonstration tank sends water to a growing tray; a larger drain returns it to the tank.
