Combined with algae, vitamins and other phytohormones, the BioTab flowering booster will allow you to increase the yield of your plants .
At Growled and we are keen to provide you with correct information and after tests on our plantations we advise you to use organic PK 5-8 in the following way on your crop:
During flowering, dilute 10ml of organic PK in 1 liter of water and water each plant during the 3rd, 4th, 5th and 6th week.
Or
from the second week of flowering until harvest add 1 to 3ml of organic PK in a liter of water each time you water your plants.

If you are using a system like AutoPot, make sure to turn off the automatic watering 24 hours before and after applying to avoid any risk of blockage.
The difference between these two methods of applying Bio PK 5-8 lies mainly in the regularity and timing of nutrient input:
In summary, the first method aims for a more intense effect at a critical moment, while the second favors gentle and consistent support throughout the flowering cycle. Depending on your goal - a punctual boost or regular support - you can adjust the application.
To avoid over-fertilization with Bio PK 5-8 from BioTabs, it is essential to strictly adhere to the recommended dose: between 1 and 3 ml per liter of water at each watering during the flowering period, starting from the second week until one week before harvest.
Alternatively, you can apply 10 ml per plant, diluted in at least 1 liter of water, once a week during weeks 2 to 6 of flowering. Both methods ensure balanced nutrition without the risk of overloading.
Note, this product is not suitable for drip irrigation systems; prefer manual watering to avoid clogging the pipes.
The Bio PK 5-8 from BioTabs is recognized as a flowering booster that promotes better size and a more pronounced aroma of the flowers. However, there are no precise data on the average yield gain expressed in grams per watt (g/watt) over the entire flowering period according to usual protocols.
Its recommended use is to add between 1 and 3 ml per liter of water at each watering, or 10 ml per plant per week during weeks 3 to 6 of flowering, which clearly optimizes floral development. For a personalized estimate of yield improvement, direct experimentation in your growing conditions remains the best approach.
If you want to maximize your yield under LED, you can also look into our LED horticultural solutions, perfectly suited to accompany this type of nutrient during flowering.
For an indoor micro-culture of 60x60 cm, Bio PK 5-8 is ideally dosed between 1 and 3 ml per liter of water with each watering, starting from the second week of flowering until one week before harvest.
Alternatively, it is possible to apply directly 10 ml per plant, diluted in at least 1 liter of water, during weeks 2 to 6 of flowering. This method ensures good stimulation of floral production and quality of trichomes.
Caution should be taken not to use this product with an automatic irrigation system to avoid any risk of clogging.
To maximize yield in g/watt with Bio PK 5-8 - BioTabs on an auto-flowering or photoperiod culture, it is recommended to apply 1 to 3 ml per liter of water at each watering starting from the second week of flowering, until about a week before harvest.
Another effective method is to apply 10 ml per plant, diluted in at least 1 liter of water, during weeks 3 to 6 of flowering. These dosages promote a dense and rich flowering thanks to the contributions of phosphorus, potassium, and trace elements.
Be careful not to use Bio PK 5-8 with an automatic irrigation system to avoid any risk of clogging. By following these recommendations, you will optimize the health of the plants and their production, contributing to a very good yield per watt consumed.
Bio PK 5-8 from BioTabs is recognized for its stability and effectiveness over several growing cycles. With its 100% organic composition rich in essential nutrients, vitamins, and trace elements, it promotes optimal flowering, good root growth, and improved harvest quality.
After several uses, it significantly contributes to yield increase, with larger and more fragrant flowers, while enhancing the natural resistance of plants against environmental stresses.
Regarding side effects, no harm is reported: this organic booster minimizes the risk of salt accumulation and avoids root burns, thus ensuring good health for the plants and stable substrate in the long term.
In summary, Bio PK 5-8 is a reliable choice to accompany several cycles without loss of efficiency, with a clear improvement in yield and robust plants.
Alternatively, a weekly dosage of 10 ml per plant diluted in at least 1 liter of water during weeks 3 to 6 of flowering is also recommended. These practices ensure optimal flowering while preserving the health of your plants.
No specific data allows to quantify the exact difference in yield between these two methods, but it can be noted that the concentrated mode targets a key phase to quickly maximize volume, while the diluted mode ensures steady and sustainable growth.
The choice thus depends on your strategy: are you looking for a one-time "boost" effect or consistent nutrition throughout flowering?
To optimize the use of Bio PK 5-8 on different varieties in bloom in the same room, start with a low dose of 1 ml per liter of water, applied at each watering from the 2nd week of flowering. You can also prefer individual watering, diluting 10 ml per plant in 1 liter of water once a week. This method allows adjusting the quantities according to the size or specific needs of each variety.
Carefully monitor the condition of the leaves and vigor to detect signs of deficiencies (yellow leaves) or excess (burns), and gradually adjust the doses. Avoid drip systems to prevent any risk of clogging, and do not exceed the 6th week of flowering to apply this booster.
The key lies in controlled application, personalized manual watering, and regular observation to achieve harmonious blooming of all your varieties without overdosing or deficiencies.
Moreover, it sustainably improves root health and the plant's resistance to environmental stress, ensuring optimal flowering over several cycles. However, this product is better suited for hydroponic systems with manual watering rather than drip systems that could clog due to the organic matter.
Bio PK 5-8 consumption per plant over 4 weeks of flowering: count about 40 ml per plant, diluted in 4 liters of water (10 ml per liter, once a week during weeks 3 to 6).
Average yield and increase %: there are no precise quantitative data. This product mainly improves the quality of flowering (size, aromatic intensity) rather than directly increasing the volume of crops.
Optimization for 1.5 x 1.5 m: depending on the density (e.g. 9 plants at 50 cm intervals), apply 10 ml per plant each week, totaling about 90 ml diluted in at least 9 liters of water per application. Individual application allows for precise dosing and avoids overdosing.
Important: apply manually, never through drip systems, to preserve the proper functioning and consistency of the product.
The Bio PK 5-8 from BioTabs is a liquid organic flowering booster to ideally be used from the second week of flowering until one week before harvest, at a rate of 1 to 3 ml per liter of water at each watering or 10 ml per plant once a week.
For integration into an automated irrigation system, it is important to know that this product can clog pipes of drip systems as it contains organic matter. Therefore, its direct use in these systems is not recommended.
If you are using a system like AutoPot, you need to stop automatic watering 24 hours before and 24 hours after application to manually apply the diluted solution. This helps to avoid any clogging and ensures optimal nutrition.
In summary, to optimize flowering with Bio PK 5-8, prefer manual application or a temporary pause in automatic watering, while respecting the recommended doses.
The Bio PK 5-8 - BioTabs - Flowering Booster is not suitable for use with an automatic irrigation system, particularly drip systems. Indeed, this liquid organic booster can quickly clog pipes and emitters, compromising their operation.
For precise dosing during flowering, it is better to apply it manually during watering, following the recommended doses (1-3 ml per liter of water or 10 ml per plant once a week between weeks 2 and 6 of flowering). This method of application ensures optimal efficacy without the risk of obstruction.
The Bio PK 5-8 from BioTabs, as a 100% organic flowering booster, promotes a higher quality resin production than a conventional fertilizer. It stimulates larger and more fragrant flowers, resulting in denser resin. Thanks to its formulation rich in vitamins, trace elements, and natural extracts, it also improves plants' resistance to stress, supporting optimal resin biosynthesis.
Unlike mineral fertilizers, it avoids the risks of root burns and salt accumulation, thus preserving root health and substrate stability over time. These conditions contribute to a more consistent and sustained resin production. In summary, Bio PK 5-8 provides a gentle and balanced nutritional input, promoting rich flowering and quality resin without negative side effects.
The main difference between these two methods of using Bio PK 5-8 - BioTabs lies in the growth strategy:
At 10 ml/l from the 3rd to the 6th week, you give a powerful boost to flowering, promoting rapid development and a larger bud volume.
In contrast, a lower dose of 1 to 3 ml/l from the 2nd week until harvest ensures continuous and gradual nutrition, ensuring optimal plant health and stable quality throughout the flowering period.
Therefore, the yield can vary depending on whether you prioritize a concentrated growth peak or a steady progression, with the first method favoring a larger volume in a shorter time frame, while the second supports consistent and homogeneous production.
Bio PK 5-8 from BioTabs is a highly valued organic liquid fertilizer that stimulates flowering due to its rich composition of phosphorus, potassium, algae, vitamins, and phytohormones. Many growers report a noticeable improvement in the volume and fragrance of flowers, as well as increased stress resistance and accelerated regeneration.
Regarding a measurable yield increase under real conditions, feedback is positive, but there are no formal published scientific studies confirming a precise quantifiable impact. The product remains a recognized bloom booster for its overall quality and beneficial effects.
As for consistency from one bottle to another, BioTabs ensures rigorous quality control and recommends strict dosing. However, no formal guarantee or specific certification on the absolute stability of one production to another is mentioned in the official documents.
In summary, Bio PK 5-8 is a reliable and proven choice to enhance flowering and improve flower quality, with consistent quality in line with the standards of a recognized organic brand.
The Bio PK 5-8 is a powerful organic fertilizer to boost flowering, but it is not recommended for home hydroponic crops, especially those with drip or automatic systems. Indeed, its organic composition can cause a clogging of irrigation pipes and lead to a nutrient imbalance due to the accumulation of salts, which can harm root health.
For a healthy and efficient hydroponic culture, it is preferable to use fertilizers specifically designed for hydroponics to avoid any technical or nutritional risks.
