by Alan Wood
If you are hesitating to grow marijuana indoors as it seems to be complicated and tricky, well, you’re wrong. Despite some challenges that you may encounter as a beginner, growing marijuana plants does not require you to have a green thumb, unlike what everybody thinks. Stop dwelling into false information about how to grow weed indoors and take a look at this step-by-step guide from Weekend Gardener to help you. (View the Infographic Here.)
1. Germination

For lighting, you need 18-24 hours per day, especially during vegetative state. The humid needs to be in between 70% and 90%, while the temperature must be 71° to 90° Fahrenheit (approximately 21° to 33° Celsius).
To do germination, soak two sheets of paper towels in the water. However, ensure that the towels are only damped, not soaking wet. Put one towel on the plate, then place the marijuana seeds about an inch apart from each other. Cover the seeds with the second paper sheet, then place another plate on the top of it.
2. Seedling Stage
For the second step, there is another set of conditions that you need to follow:
- Humidity: 70%
- Light: 18-24 hours
- Temperature: 71°-77°F
You can determine if the plants are already on the seedling stage if the white roots already reached two to three millimetres. In this case, you have to move the seeds to a growing medium, which can be soil (best smell and most uncomplicated growth), coco (best overall), or hydroponics (highest yields but hardest to grow). After placing the seeds, plant them 10mm deep into your chosen medium. Remember to keep the medium damp, not overwatered.
3. Vegetative Stage
The vegetative stage needs the following conditions:
- Humidity: 50%-70%
- Light: 18-24 hours
- Temperature: 70°-85°F
- Try training your plants using these advanced techniques for higher yields as preparation for the flowering stage:
- Scrog
- Super Cropping
- FIMing
- Topping
- SOG
- Lollipopping
4. Flowering Stage
Required Conditions:
- Humidity: 40%-50%
- Light: 12 hours
- Temperature: 65°-80°F
If your plants have budded flowers, then you are near to the success of growing marijuana indoors even as a beginner. However, this stage has four phases that have different growing requirements.
- During phase one, continue giving nutrients to the plants.
- For phase two, stop training the plants.
- Phase three is when the plants reached the full flowering stage.
- For phase four or flushing, stop giving nutrients and provide them with pH-balanced water instead.
5. Harvesting
Necessary Conditions:
- Humidity: 50%
- Light: Not needed anymore
- Temperature: 70°F
In harvesting the first-ever marijuana that you have grown indoor, the first step is to cut the main stem. Then, hang the plants to dry it up. Wait until its stems bend and break slightly, indicating that the plant is already dried up enough.
