Foliar feeding is a method of delivering nutrients directly to your plants through their leaves. When using Reiziger Bud Booster for foliar feeding, you're providing your plants with a potent blend of nutrients that can enhance their flowering presence.
Procedure for Foliar Spray with Reiziger Bud Booster:
1. Preparation: Begin by filling a container with demineralised (RO) water. Aim for about 0.5-0.6L per m² of plant canopy. Adjust the quantity based on plant needs and growing conditions.
2. Mixing: Add the required amount of Reiziger Bud Booster to the water and stir until uniformly mixed. The organic contents in the Bud Booster can settle over time, so ensure you shake it well before use. There's no need to adjust the pH.
3. Initial Watering: Before spraying, saturate the growing medium with your regular nutrient solution. This step is crucial as it prevents the plant from absorbing excessive Bud Booster, which could lead to leaf burn.
4. Temperature Control: Lower the ambient temperature to around 72°F (22°C) and use dehumidifiers to maintain a humidity level of 55-65%. This helps in preventing mold and mildew issues.
5. Spraying: Mist the underside of the leaves to ensure total coverage but avoid excessive runoff. Then, spray over the top for complete saturation of all plant foliage. After spraying, allow around 3-4 hours for drying before turning on high intensity grow lights.
By following this procedure, you ensure that your plants receive a direct boost of essential nutrients, enhancing their growth and flowering potential. The Reiziger Bud Booster is specially formulated to provide optimal results when used as a foliar feed, making it a top choice for cannabis craftsmen.

The optimal time to introduce phosphorus and potassium bloom boosters is during the third stage of the generative phase, roughly three to four weeks before harvest. Overuse of PK boosters can disrupt nutrient balance, reducing Calcium and Magnesium availability. Maintaining this balance in the flowering phase is vital for optimal essential oil and terpene production.

REIZIGER nutrients are designed with separate A&B components to cater to plants' diverse needs at different growth stages. These components, when in their concentrated forms, can counteract each other, hence the need for separate mixing.

To prevent unwanted growth in your reservoir, keep it covered, maintain optimal temperatures, and clean it regularly between crops and growth stages.

Even if plants haven't consumed all the nutrients, the solution can degrade over time due to factors like temperature, light, and microbial activity. As a rule of thumb, many hydroponic growers change their nutrient solution every 1-2 weeks, but this can vary based on the specific system and conditions.

Maintaining the right temperature for your nutrient solution is essential not only for plant health but also to prevent the proliferation of harmful pathogens. Ideally, your reservoir temperature should be kept between 65-70°F (18-21°C). If maintaining this range proves challenging, it's advisable to change the solution more frequently to ensure plant safety. For your grow room, aim for temperatures of 70-84°F (21-29°C) during the day and a cooler 68-71°F (20-22°C) at night for optimal plant growth and development.

Chlorine evaporates upon exposure, ensuring that by the time the nutrient solution reaches the roots, it's chlorine-free.
