NOTES:
#01 Base A Coco & #02 Base B Coco
-
Use #01 Base A & #02 Base B always together.
-
#01 Base A and #02 Base B NEVER mix directly, always via water.
-
Always add #01 Base A first, mix/stir well.
-
Then add #02 Base B, mix/stir well.
-
Always use #01 Base A & #02 Base B in equal amounts.
#03 Root Stimulator
-
Excessive use can make the plant feel “too wet.”
-
Never use all three together with #04 Veg Care and #05 Growth Vitalizer.
#04 Veg Care
-
Not suitable for the flowering phase — delays the transition to flowering.
-
Never use all three together with Root Stimulator (#03) and Growth Vitalizer (#05).
#05 Growth Vitalizer
-
Growth booster for strong, compact growth.
-
Helps with growth deficiency, slow plants, and improves leaf structure.
-
Stop using in week 3; continuing causes plants to stretch.
-
Never use all three together with #03 Root Stimulator and #04 Veg Care.
#06 Bud Enhancer
-
Activates flowering and ensures more compactness.
-
Increases flower density → works together with PK, but is not dependent on PK.
-
Works well together with #07 Flora Core and contributes to the shape and seize of the flowers.
#07 Flora Core
-
Enhances aroma, resin production, and flower structure.
-
Constant light dosing works best.
-
Using it too early delays growth.
#08 PK-P
-
Ensures larger buds; be careful with excessive use, as it can undermine density.
-
Week 6 is critical for bud structure and density.
-
Overdosing causes burnt leaf tips.
-
After adding #09 Bloom Tam, reduce PK-P.
#09 Bloom Tam
-
Strong flower stimulator, especially for weight and resin production.
-
A higher dosage of Bloom Tam means PK-P should be reduced.
-
In late flowering, very high dosing is possible
-
Ensures “ripening” of buds and increases yield.
-
Using it too early leads to overfeeding and premature flowering push.
Start of the cycle
-
The cycle starts after transplanting into the final pots
-
The growth schedule assumes an average of three feedings per week.
-
After an average of 3 feedings, give water once.
-
Always monitor the condition of the plants and adjust timing and dosages accordingly.
-
The P2TP-Holland growth schedule serves as a general guideline for producing proven high-quality flowers.
Grow Phase, week 1, 2 & 3
#01 Base A Coco
#02 Base B Coco
#03 Root Stimulator
#04 Veg Care
#05 Growth Vitalizer
We start with light dosages of the products above and gradually increase it until the end of week 3.
#03 Root Stimulator, #04 Veg Care, and #05 Growth Vitalizer are used alternately in this phase.
See the growth schedule for exact dosages.
Early flower phase, week 1, 2 & 3
#01 Base A and #02 Base B is maintained at 4.0 ml/L in week 1 for the first time and then reduced to 3.5 ml/L until the end of week 4.
The dosages of #03, #04, and #05 are reduced and combined according to the following schedule:
#03 + #05
#03 + #04
#04 + #05
#06 Bud Enhancer: start with 1.0 ml/L until the end of week 3
#07 Flora Core: Start once with 1.0ml/L, increase to 2.0 ml/L at the second application in week 1; this dosage remains the same throughout the cycle.
Mid flower phase, week 4, 5 & 6
#01 Base A and #02 Base B;
- remain at 3.5 ml/L in week 4
- reduced to 3.0ml/L in week 5
- reduced more quickly in week 6 due to the increase of #08 PK-P and the addition of #09 Bloom Tam.
#06 Bud Enhancer: Start week 4, increase to 2.0 ml/L until the end of week 7 / beginning of week 8.
#07 Flora Core: 2.0 ml/L until the end of week 7 / beginning of week 8.
#08 PK-P:
Week 4: 1.0 ml/L
Week 5: 2.0 ml/L
Week 6: 2.5 ml/L
#09 Bloom Tam: Start in week 6 with a light dosage, increase with each application.
Note:
#03 Root Stimulator is shown in the schedule as once per week. Low supplementary dosages once a week are possible in case of stress or root demand.
Late flower phase, week 7, 8 & 9
#01 Base A and #02 Base B is reduced to 1.0 ml/L in week 7.
#06 Bud Enhancer and #07 Flora Core remain at 2.0 ml/L until the end of week 7 / beginning of week 8.
#08 PK-P is reduced to 1.0 ml/L in week 7.
#09 Bloom Tam is increased with each application.
Week 9: Flush with water 3 to 4 times.
NOTE:
At the beginning of week 8, based on the condition and ripeness of the plants, it is assessed whether the feeding schedule continues according to week 7, third application. If the plants need more time to ripen further, this schedule is temporarily maintained. Depending on this, the application of #09 Bloom Tam will be done in the beginning or the end of week 8.
The application of #09 Bloom Tam alone is done as shown in the growth schedule. #09 Bloom Tam is applied 2 to 3 times, every day. So, three days in a row
NOTE:
In week 7, water supply is reduced to about 1.0 liter per plant.
In week 8, water supply is further reduced to about 0.5 liter per plant, adjusted to the actual water uptake of the plants.
This gradual reduction of water supply helps to limit excess moisture in the substrate and crop and reduces the risk of mold formation (such as bud rot) during the late flowering phase.
Watering:
The use of reverse osmosis (RO) water is strongly recommended.
This schedule assumes the use of tap water with an EC value of approximately 0.2.
Maintain the nutrient solution at a pH between 5.8 and 6.2.
Keep the water temperature between 17 °C and 20 °C.
