    What is the most important step in the drying process?

    • Using the oven

    • Singing to plants

    • The first 72 hours of uninterrupted darkness

    • Immediately put the flowers in sealed jars

    Correct Answer
    A. The first 72 hours of uninterrupted darkness
    Explanation
    The first 72 hours of uninterrupted darkness is the most important step in the drying process because it allows the flowers to properly dry and cure. During this period, the flowers are protected from light, which can degrade the quality of the final product. Darkness helps to preserve the potency and flavor of the flowers. It also allows for optimal moisture evaporation, preventing the growth of mold or mildew. Therefore, ensuring the first 72 hours of uninterrupted darkness is crucial for a successful drying process.

    When preparing your nutrients, you should

    • Use cold water

    • Put in nutrients individually then test ph

    • Change ph, then add nutrients

    • Use hot water

    Correct Answer
    A. Put in nutrients individually then test ph
    Explanation
    When preparing nutrients, it is important to put in each nutrient individually and then test the pH. This is because different nutrients may have different pH levels, and mixing them together before testing the pH can result in an incorrect reading. By adding the nutrients one by one and testing the pH after each addition, you can ensure that the pH is properly adjusted before moving on to the next nutrient. This helps to create optimal conditions for nutrient absorption by the plants.

    What are the sulfur burners used for

    • Lack of nutrients

    • Spider Mites

    • Powder Mildew

    • Aphids

    Correct Answer
    A. Powder Mildew
    Explanation
    Sulfur burners are used for controlling and preventing powder mildew. Powder mildew is a fungal disease that affects plants, causing a white powdery coating on leaves, stems, and flowers. Sulfur is an effective treatment for powder mildew as it acts as a fungicide, inhibiting the growth and spread of the fungus. When sulfur burners are used, they release sulfur dioxide gas, which helps to control and eliminate the powder mildew spores present in the air and on the plant surfaces.

    How many hours of darkness do you need for flowering?

    • 6 hours

    • At least 12 hours

    • 3 hours

    • 10 hours

    Correct Answer
    A. At least 12 hours
    Explanation
    Plants require a certain amount of darkness to initiate the flowering process. This is because the length of uninterrupted darkness triggers the release of certain hormones that stimulate flower development. In order for flowering to occur, a minimum of 12 hours of darkness is needed. Anything less than this may inhibit or delay the flowering process. Therefore, the correct answer is "At least 12 hours".

    Charcoal filters are used for

    • Changes the flavor of cannabis

    • Filters the ait

    • Eliminate odor

    • Filters airborne disease

    Correct Answer
    A. Eliminate odor
    Explanation
    Charcoal filters are commonly used to eliminate odor. When air passes through the filter, the activated charcoal absorbs and traps odor-causing molecules, effectively removing the unpleasant smell. This makes charcoal filters a popular choice for various applications where odor control is necessary, such as in air purifiers, water filters, and even in grow rooms to control the smell of cannabis. However, it is important to note that charcoal filters do not filter airborne diseases, as they primarily focus on removing odors.

    What is the 1st sign of spider mites?

    • Webbing

    • Brown leaves

    • Little Black Insects

    • White dots on leaves

    Correct Answer
    A. White dots on leaves
    Explanation
    The first sign of spider mites is the presence of white dots on leaves. Spider mites are tiny pests that feed on plant sap, causing damage to the leaves. As they feed, they puncture the plant cells, leading to the formation of small white dots on the leaves. These dots are actually the damaged plant cells and can be an early indication of a spider mite infestation. It is important to identify and address this issue promptly to prevent further damage to the plant.

    The earliest you can determine the sex of a cannabis plant is:

    • When the plant is three months old

    • During the first 2 weeks of flowering

    • During the first month of vegetative growth

    • All of the above

    Correct Answer
    A. During the first 2 weeks of flowering
    Explanation
    During the first 2 weeks of flowering, cannabis plants start to show their sex characteristics, making it possible to determine their sex. This is because female plants begin to develop small white hairs called pistils, while male plants start to produce small sacs called pollen sacs. By closely observing the plants during this stage, it becomes easier to identify their sex and take appropriate actions such as removing male plants to prevent pollination.

    What is a desirable level of humidity for your grow room?

    • 10-20%

    • 20-30%

    • 30-50%

    • 75-85%

    Correct Answer
    A. 30-50%
    Explanation
    A desirable level of humidity for a grow room is 30-50%. This range provides enough moisture for plants to thrive without promoting the growth of mold or mildew. Humidity levels below 30% can lead to dryness and dehydration of plants, while levels above 50% can create a damp environment that encourages the growth of harmful fungi. Therefore, maintaining a humidity level between 30-50% is ideal for optimal plant growth and health in a grow room.

    Cannabis should be watered:

    • When the plants and leaves are limp

    • 3 times per day

    • Every 3 days

    • When the medium is bone dry

    Correct Answer
    A. Every 3 days
    Explanation
    Cannabis should be watered every 3 days. This is because watering too frequently can lead to overwatering and root rot, while watering too infrequently can cause the plants to become dehydrated. By watering every 3 days, it allows the soil to dry out slightly between waterings, ensuring that the plants receive enough moisture without risking waterlogged roots. Additionally, this watering schedule helps promote healthy root growth and prevents the development of mold or fungus in the soil.

    • HPS have different light spectrum than metal halide

    • All of the above

    Correct Answer
    A. HPS have different light spectrum than metal halide
    Explanation
    HPS bulbs have a different light spectrum compared to metal halide bulbs. This means that the type of light emitted by HPS bulbs is different from the type emitted by metal halide bulbs. This difference in light spectrum can affect the way colors appear under the light and can also impact plant growth. Therefore, the correct answer is that HPS bulbs have a different light spectrum than metal halide bulbs.

    Which of the following pests is the LEAST harmful?

    • Thrips

    • White fly

    • Spider mites

    • Aphids

    Correct Answer
    A. White fly
    Explanation
    White flies are considered the least harmful pest because their feeding damage is relatively minimal compared to other pests listed. While they can cause damage to plants by sucking sap and transmitting diseases, their impact is generally less severe than that of thrips, spider mites, or aphids. Thrips can cause significant damage by feeding on plant tissues and spreading viruses, while spider mites can cause leaf discoloration and webbing, and aphids can reproduce rapidly and cause stunted growth and deformities in plants. Therefore, among the given options, white flies are the least harmful.

    When is it time to harvest?

    • When the plant is 6 feet tall

    • When the growth stops

    • When calyxes swell and enlarge

    • When the pistels turn from white to red

    • All of the above

    Correct Answer
    A. When the pistels turn from white to red
    Explanation
    The pistils of a plant are the female reproductive organs that are responsible for capturing pollen. When the pistils turn from white to red, it indicates that the plant is reaching its maturity and is ready for harvest. This change in color signifies that the plant has completed its reproductive cycle and is now producing mature seeds. Therefore, when the pistils turn from white to red, it is the ideal time to harvest the plant.

    How many hours of light do you use for vegetative plants?

    • 6 hours

    • 14 hours

    • 12 hours

    • 18 hours

    Correct Answer
    A. 18 hours
    Explanation
    In order to promote vegetative growth in plants, they require a longer duration of light exposure. The process of photosynthesis is essential for plant growth, and providing a longer period of light allows plants to produce more energy and grow more rapidly. Therefore, using 18 hours of light is recommended for vegetative plants to ensure optimal growth and development.
