Why Indoor Genetics Make a Difference

Indoor strains have been selected over generations for artificial light sources (LED, HPS, CMH). They respond optimally to 18/6 or 20/4 light cycles during the vegetative phase and 12/12 for inducing flowering. The result: denser buds, higher THC concentration, and a more intense terpene profile than many outdoor strains.

Indoor Cultivation Setup for Germany

  • Grow Tent: 60x60 cm for 1 plant, 120x120 cm for 2–3 plants (CanG limit)
  • Light: LED Full-Spectrum or HPS – min. 400W for 1m²
  • Humidity: Veg 60–70%, Bloom 40–50%, Late Bloom under 45%
  • Temperature: 22–28°C during the day, 18–22°C at night

FAQ: Indoor Cannabis Seeds

Feminized or Autoflower for Indoor?

Both work great. Feminized strains give you more control over the vegetative phase and higher yields. Autoflowers are faster (9–11 weeks) and don't require a light change – ideal for beginners.

How many plants can I grow indoors?

According to CanG, a maximum of 3 flowering plants per adult. The cultivation area must be protected from access by minors.

Which light cycles do I need?

Feminized strains: 18/6 in the veg phase, 12/12 to induce flowering. Autoflowers: constantly 18/6 or 20/4 from seed to harvest.

Legal notice: The cultivation of cannabis in Germany is limited by CanG to a maximum of 3 flowering plants per adult. The cultivation area must be protected from access by minors.
