Plants & Herbs for Indoor Growing
  • Do herbs grow better indoors or outdoors?
    In Nordic and Northern European climates, herbs generally grow more reliably indoors over the whole year, while outdoor growing works best only during the short summer season. Outdoors in Northern Europe, herbs grow very well in late spring and summer thanks to long daylight hours. However, the growing season is short, and weather can be… Read more: Do herbs grow better indoors or outdoors?
  • How long do herbs take to grow?
    How long herbs take to grow depends on the growing method and the type of herb. In general, herbs grow faster in hydroponic systems than in soil pots because water, nutrients, and oxygen are delivered more efficiently to the roots. Below is a general comparison, ordered from fastest to slowest, based on typical indoor conditions.… Read more: How long do herbs take to grow?

Hydroponics & Indoor Systems
  • What is a hydrogarden?
    A hydrogarden is an indoor garden that grows plants using hydroponics, meaning plants grow in water with added nutrients instead of soil. In a hydrogarden, plant roots receive water, nutrients, and oxygen directly, which supports steady growth indoors. Most hydrogardens include a water reservoir, plant holders or baskets, and often LED grow lights to replace… Read more: What is a hydrogarden?
  • Do plants grow faster hydroponically or in soil?
    In most indoor setups, plants grow faster hydroponically than in soil, especially herbs and leafy greens. The main reason is that hydroponics delivers water, nutrients, and oxygen directly to the roots, which reduces the effort plants need to grow. In soil, roots must spread out to find water and nutrients, and growth can slow down… Read more: Do plants grow faster hydroponically or in soil?
  • What indoor plants can be grown hydroponically?
    Many indoor plants grow very well hydroponically, especially herbs, leafy greens, and compact edible plants. These plants benefit from constant access to water and nutrients and do not need deep soil or large root space. Indoor plants that grow well in hydroponic systems include: These plants are well suited for hydroponics because they stay relatively… Read more: What indoor plants can be grown hydroponically?
  • Is hydroponics better than soil for indoor growing?
    Hydroponics is often better than soil for indoor growing, especially for herbs, leafy greens, and salads. The main reason is control.
