Steps of cultivation 1. Soak the seeds for 4 to 6 hours and then drain them 2. Prepare growth medium and generously moisten the surface 3. Distribute seeds evenly and avoid partial accumulations, moisten 4. Cover and weigh down with any cover (e.g. a paving stone) 5. Very long germination, it occurs in 1 - 2 days 6. Remove cover and transfer to aquaponics system 7. After 7 to 10 days, the ripe microgreens can be harvested 8. Harvesting should take place in the morning or evening due to cooler temperatures Image: https://www.hippopx.com/en/query?q=seedling Context: ID: 509 |

Cannabis sativa L., from Köhler's medicinal plants
Cannabis: Early substitute for cotton or linen (clothing, ropes, etc.) and
also used as medicine.Cultivation
Preferred systems NFT Nutrient Starting phase Yield phase Dose - + - + NO3 10.0 K 5.0 1.0 Approx 1.0 0.8 B 20.0 Fe 10.0 All information in mmol See also: deficiency symptoms Cannabis is an annual plant; the entire life cycle lasts one year, although the plant often ends its life cycle after just four to ten months. Depending on the growth phase, the appearance of the plant and its needs change. This requires different amounts of light, water and nutrients.
Here are the four (main) phases:
1st germination phase (1 to 2 weeks)- Cultivation: paper towel/moist, Jiffys, coconut mat, etc.
- Duration: between 24 hours and 7 days. Cannabis strains with a high indica content germinate faster than sativas.
2. Seedling phase (2 to 4 weeks)- Susceptible to disease and mold.
- As much light as possible.
- The duration of the seedling phase depends on the variety and environmental factors
- When the plant produces the full number of fingers on a new leaf, the seedling phase is complete.
3. Growth phase / vegetation phase (2 to 8 weeks)- Growth up to 5 cm per day.
- Duration / rough estimate: Autoflowering cannabis strains enter the flowering phase after 2 to 3 weeks. Regular or feminized strains only start flowering when the days get shorter. In the northern hemisphere this is the summer solstice on June 21st. of the year (outdoor). Indoors, lighting time is reduced to 12 hours or less.
4. Flowering phase (4 to 12 weeks)- Beginning of reproduction.
- Only now can the gender be determined with certainty.
- Special fertilizer can be used here to stimulate flower formation.
- Much water.
- Possibly support the plant so that it can support the weight of the flowers.
- In view of hormone production, it should be cut back to a maximum of the second week of the flowering phase.
- Duration of the flowering phase: Variety dependent. Autoflowering cannabis can be ready to harvest in as little as a month, while indica takes around 6 to 8 weeks.
- Some sativa strains can take over 3 months.

pH and Ec: Cannabis
Nutrients that cannabis needs can be divided into three categories: Primary macro-nutrients, secondary macro-nutrients and micro-nutrients. This division is based on how much of each nutrient the plant needs.
Nitrogen, for example, is categorised as a primary nutrient because the plant needs more of it than calcium or sulphur, for example. Cannabis has different nutrient requirements in different phases. Nitrogen, for example, is mainly needed in the growth phase, but much less in the flowering phase.
On the other hand, the need for other nutrients, such as phosphorus, increases. In the growth and flowering fertilisers from well-known manufacturers, the nutrients are already optimally adapted in each case. (You can find more about the correct fertilising depending on the phase of life further down in the text).
