FAQs
What is Advanced Nutrients Sensi Bloom A+B?
Advanced Nutrients Sensi Bloom A+B is a two-part base nutrient system specifically formulated for the flowering stage of plant growth. It provides a balanced blend of macro and micronutrients essential for robust bloom development. This pH-perfect formula adjusts to your water's pH, ensuring optimal nutrient uptake. Sensi Bloom A+B supports vibrant flower production, enhances terpene profiles, and promotes overall plant health during the critical blooming phase.
When should I use Sensi Bloom A and B?
Start using Advanced Nutrients Sensi Bloom A+B when your plants begin to show signs of flowering. This is typically when the light cycle changes or when natural daylight hours decrease. Continue using Sensi Bloom A+B throughout the entire flowering stage until about 1-2 weeks before harvest. For most plants, this means using it for 6-8 weeks, but the exact duration can vary depending on the specific strain and growing conditions.
What is Sensi Bloom used for?
Sensi Bloom is used to provide essential nutrients during the flowering stage of plant growth. It supports the development of flowers, buds, and fruits by delivering a precise ratio of nutrients tailored for bloom production. This formula enhances flower size, density, and quality while promoting overall plant health. Sensi Bloom also helps in developing rich aromas and flavours in flowers and fruits.
How do you use Sensi Bloom A and B in soil?
To use Sensi Bloom A and B in soil, first shake both bottles well. Mix equal parts of A and B into your water, typically 4ml per liter of each part for normal feeding. Always add part A first, stir thoroughly, then add part B. Use this nutrient solution to water your plants as needed, usually every other watering. Adjust the concentration based on your plants' needs and growth stage, and always monitor for signs of over or underfeeding.
Can I mix Sensi Bloom A and B together?
To use Sensi Bloom A and B in soil, first, shake both bottles well. Mix equal parts of A and B into your water, typically 2mL per litre of each part for normal feeding. Always add part A first, stir thoroughly, then add part B. Use this nutrient solution to water your plants as needed, usually every other watering. Adjust the concentration based on your plants' needs and growth stage, and always monitor for signs of over or underfeeding.
Is Sensi Bloom suitable for all types of plants?
Sensi Bloom A+B is formulated to benefit a wide range of flowering plants, including vegetables, fruits, and herbs. It's particularly popular among growers due to its ability to support high-value crop production. However, it can be used for any plant in its flowering stage. Always start with the recommended dosage and adjust based on your specific plant's needs and response.
How often should I feed my plants with Sensi Bloom?
The frequency of feeding with Sensi Bloom A+B depends on your plants' growth stage and needs. Generally, use it with every watering during peak flowering. In soil, this might mean every 2-3 days. In hydroponic systems, it's typically used continuously. Monitor your plants closely and adjust the feeding schedule as needed. Some growers alternate between nutrient feedings and plain pH-adjusted water to prevent nutrient build-up.
Can Sensi Bloom be used in hydroponic systems?
Yes, Sensi Bloom A+B is excellent for hydroponic systems. Its pH-perfect formula makes it ideal for water-based growing methods. When using in hydroponics, start with a lower concentration (about 25% of the recommended dose) and gradually increase as needed. Monitor your plants closely and adjust the nutrient strength based on their response. Remember to change your nutrient solution regularly to maintain optimal nutrient levels.  
What's the difference between Sensi Bloom and Sensi Grow?
Sensi Bloom and Sensi Grow are both base nutrients, but they're formulated for different growth stages. Sensi Grow is designed for the vegetative stage, promoting leaf and stem development. It has higher nitrogen levels. Sensi Bloom is for the flowering stage, with higher phosphorus and potassium levels to support flower and fruit production. Switch from Grow to Bloom when your plants start showing flowering signs.
Can I use Sensi Bloom with other Advanced Nutrients products?
Yes, Sensi Bloom A+B is designed to work synergistically with other Advanced Nutrients supplements. You can enhance your feeding regimen with products like Big Bud, Overdrive, or B-52 for targeted benefits. Always introduce new products gradually and monitor your plants' response. When combining products, you may need to adjust the concentration of each to avoid overfeeding.
