1. The 5 best CBD cannabis strains for your grow box

If you want to get the most out of your CBD cannabis grow box, choosing the right strains is crucial. Here are the five best CBD-rich cannabis strains that are great for indoor cultivation:

1. Cannatonic

Cannatonic is a true legend among CBD varieties. With a CBD content of up to 17% and a very low THC content of less than 1%, it is perfect for medicinal purposes. The plant grows compactly and is therefore ideal for your grow box. It flowers quickly and delivers a rich harvest after about 9-10 weeks.

2. ACDC

ACDC is a Cannatonic cross and offers an even more extreme CBD:THC ratio of around 20:1. With CBD levels of up to 24%, it is one of the most CBD-rich strains available. It grows a little larger than Cannatonic, but is easy to control with appropriate cultivation techniques.

3. Sativa Dance

For fans of sativa-dominant strains, Sativa Dance is the perfect choice. She offers a balanced 1:1 CBD:THC ratio, with both levels hovering around 5-7%. The plant grows quickly and can double its height during the flowering phase, but responds well to techniques such as SCROG.

4. Sweet Pure CBD

This variety impresses with its sweet taste and gentle aroma. With a CBD content of 8-15% and minimal THC, it is ideal for beginners. It grows compact and robust, which makes it a grateful plant for your grow box.

5. Charlotte’s Angel

Named after the famous case of Charlotte Figi, this strain offers a CBD:THC ratio of 20:1. It grows a little slower than other strains, but rewards you with dense buds and an intense aroma. Its compactness makes it perfect for confined spaces.

Variety	CBD content	THC content	Flowering period
Cannatonic	up to 17%	<1%	9-10 weeks
ACDC	up to 24%	<1%	9-10 weeks
Sativa Dance	5-7%	5-7%	10-12 weeks
Sweet Pure CBD	8-15%	<1%	8-9 weeks
Charlotte’s Angel	10-16%	<1%	11-13 weeks

When choosing your CBD cannabis strain for your grow tent, you should not only look at the CBD content, but also consider factors such as growth height, flowering time and yield. Experiment with different strains to find out which one best suits your needs and setup. Remember that genetics are only part of the success - proper care and optimal grow tent settings are just as important for a successful CBD cannabis harvest.

2. Optimal settings: light, temperature and humidity

For successful CBD cannabis growth in your grow tent, the right environmental conditions are crucial. Light, temperature and humidity play a key role. Let's take a closer look at each of these factors and go through the optimal settings for your CBD plants.

Light: The energy source of your plants

Light is the most important growth factor for your CBD cannabis plants. In the grow box you have full control over the light cycle and light intensity.

• Vegetative phase: 18-24 hours of light per day
• Flowering phase: 12 hours light, 12 hours darkness

For optimal results, we recommend LED grow lights. They are energy efficient, produce less heat, and offer a light spectrum optimized for cannabis. Look for a light intensity of 30-50 watts per square foot for the vegetative phase and 50-80 watts per square foot for the flowering phase.

Temperature: The comfortable climate for your plants

CBD cannabis thrives best in a moderate temperature range. Temperatures that are too high or too low can inhibit growth and cause stress.

Growth phase	Optimal temperature (day)	Optimal temperature (night)
Vegetative phase	20-28°C	18-24°C
Flowering phase	20-26°C	18-22°C

A slight drop in temperature at night can promote terpene production and thus improve the aroma of your CBD flowers. Make sure that the temperature fluctuations are not too extreme to avoid stress reactions.

Humidity: The often underestimated factor

The right humidity is crucial for the health of your plants and influences nutrient uptake and transpiration.

• Seedlings/cuttings: 70-80% relative humidity
• Vegetative phase: 50-70% relative humidity
• Early flowering phase: 40-50% relative humidity
• Late flowering phase: 30-40% relative humidity

In the late flowering phase, lower humidity is important to prevent mold growth and promote resin production. A dehumidifier can be very useful here.

Air circulation: fresh air for healthy plants

Good air circulation in your grow box is essential. Not only does it help regulate temperature and humidity, it also strengthens the stems of your plants and prevents mold from forming.

Install at least one small fan in your grow box to provide gentle but constant air movement. Make sure the airflow is not directed directly at the plants to avoid wind damage.

Fine-tuning these factors can take some time, but with a little patience and observation, you will find the perfect settings for your CBD cannabis grow tent. Remember that every plant is individual and may react slightly differently to environmental conditions. Regular monitoring and small adjustments are the key to success when growing CBD cannabis indoors.

3. Nutrients and watering: How to properly care for your CBD plants

An optimal supply of nutrients and water is crucial for healthy, high-yielding CBD cannabis plants in your grow tent. With the right care, you can maximize CBD content while avoiding problems such as nutrient deficiencies or overwatering.

Nutrients: The basis for strong plants

CBD cannabis requires a balanced supply of macro and micronutrients. The most important macronutrients are:

• Nitrogen (N): Promotes leaf growth and general plant development
• Phosphorus (P): Supports root formation and flower development
• Potassium (K): Strengthens plant structure and improves stress resistance

Nutrient requirements change throughout the growth cycle:

Growth phase	Nutrient ratio (NPK)
Vegetative phase	3-1-1 or 5-1-1
Early flowering phase	1-3-2
Late flowering phase	0-3-3 or 0-4-4

Use fertilizers specifically designed for cannabis and follow the manufacturer's instructions. Start with a lower dosage and increase slowly to avoid nutrient burn.

Irrigation: The right rhythm is crucial

Proper watering is an art in itself. Too much water can lead to root rot, while too little water inhibits growth. Here are some tips for proper watering:

• Only water when the top layer of soil (approx. 2-3 cm) is dry.
• Use water with a pH between 6.0 and 6.5 for optimal nutrient absorption.
• Water slowly and evenly until about 10-20% of the water runs out of the bottom of the pots.
• Avoid watering directly on the leaves to prevent mold growth.

The frequency of watering depends on various factors, such as pot size, substrate, room temperature and humidity. As a rule, plants in the vegetative phase need water every 2-3 days, while in the flowering phase they need to be watered more frequently.

Substrates: The right basis for your CBD plants

The substrate you choose has a significant impact on the nutrient and water supply of your plants. The following are particularly suitable for growing CBD cannabis in a grow box:

• Coconut soil: Light, airy and with good water storage capacity
• Peat mixtures: Provide good nutrient storage, but should be loosened with perlite or vermiculite
• Ready-made cannabis soil: Specially tailored to the needs of cannabis plants

Make sure your substrate is well drained to avoid waterlogging.

pH value: The key to optimal nutrient absorption

The pH of your substrate and irrigation water is crucial for the nutrient uptake of your CBD plants. For soil, the pH should be between 6.0 and 6.8, for hydroponic systems between 5.5 and 6.5. Check the pH regularly and correct it with pH regulators if necessary.

Foliar fertilization: An additional source of nutrients

In addition to root fertilization, foliar fertilization can be useful, especially in stressful situations or when there are nutrient deficiencies. Spray the nutrient solution finely onto the undersides of the leaves, preferably shortly after switching on the lights, so that the leaves are dry again by the time you turn them off.

With the right balance of nutrients and water, you can create optimal conditions for your CBD cannabis plants. Watch your plants closely and adjust your care strategy if necessary. Each plant is unique and can react differently to the environmental conditions. With patience and attention, you will soon be an expert in caring for your CBD cannabis grow box.

4. Harvesting and drying: Maximize the CBD content of your flowers

Timing and performing the harvest and drying process correctly is crucial to maximizing the CBD content of your cannabis flowers. This phase requires patience and precision, but will pay off in the form of high-quality CBD flowers.

Identify the optimal harvest time

The ideal harvest time for CBD-rich cannabis is slightly different than for THC-rich strains. Look for the following signs:

• The flowers feel firm and compact
• 70-90% of the pistil (flower hairs) have changed color from white to orange-brown
• The trichomes (resin glands) are mostly milky white, some are starting to turn amber
• The larger leaves begin to yellow slightly

Use a jeweler's loupe to look closely at the trichomes. For maximum CBD content, harvest when about 10-20% of the trichomes are amber.

Carry out the harvest correctly

Follow these steps for a clean and efficient harvest:

1. Stop watering 24-48 hours before harvest to improve flavor.
2. Turn off the lights and leave the plants in darkness for 24-48 hours to stimulate resin production.
3. Cut the main stems with clean, sharp scissors or a trimmer.
4. Remove large fan leaves and carefully trim excess leaf material.
5. Divide the plant into smaller, manageable branches.

The drying process: key to quality

Slow, controlled drying is crucial to preserving terpenes and cannabinoids. Follow these guidelines:

• Dry in a dark room at 15-21°C and 45-55% humidity
• Hang the branches upside down and leave enough space for air circulation
• The drying process should take 7-14 days
• The flowers are dry enough when small branches can be bent with a cracking sound

Drying too quickly can negatively affect the CBD content and aroma, while drying too slowly can encourage mold growth.

Curing: refining your CBD flowers

After drying, curing follows, a process that further improves the quality of your CBD flowers:

1. Carefully remove the flowers from the branches and place them loosely in airtight jars.
2. Only fill the jars to about 75% to allow air circulation.
3. Close the jars and store them in a cool, dark place.
4. Open the jars for 15 minutes every day for the first two weeks to "air them out".
5. After two weeks, reduce ventilation to once a week.
6. Curing should last at least 2-4 weeks, but can be continued for up to 6 months for optimal results.

Storage: Store your CBD flowers properly

Proper storage is crucial for long-term preservation of the quality of your CBD flowers:

• Store the flowers in airtight, opaque containers
• Store them at a constant temperature of about 20°C
• Maintain relative humidity at 58-62% (use humidity regulators if necessary)
• Avoid direct sunlight and extreme temperature fluctuations

If stored properly, your CBD flowers can retain their quality for up to a year.

With careful harvesting, drying, curing and storage, you can ensure that your home-grown CBD cannabis flowers reach their full potential. Remember that patience during these processes is key to high-quality, CBD-rich end products. Each step is important to preserve the valuable cannabinoids and terpenes and maximize the therapeutic effects of your CBD flowers.
