NPK fertilizer kit
The step by step user guide

Please be advised that these nutritional recommendations are indicatory and that this feeding schedule is sole to be used as a guideline. All values should be applied in accordance with your personal situation, and no rights can be derived from the use of this schedule.

Never apply more than the recommended amount and beware of over nourishment. After the second application, always provide your plants with plain water once in order to allow the plant the opportunity to absorb the remaining nutrients from the soil.

For all product information, take a look at our NPK Fertilizer Kit

Tips

Use water with a temperature around 24 °C / 75 °F.

We recommend a PH level between 6 and 7 for soil cultivation and between 5.5 and 6.5 for hydroponics. If you need to raise or decrease your pH level, mix your fertilizer first, and then adjust the PH level.

Conversion

1 gram = 0.035 ounces
1 liter = 0.26 gallon

For your convenience, MSB has included a measuring spoon which you will find in the seedling fertilizer. This spoon equals 1 gram!
