Green House Powder Feeding Mostly Sativa is a professional fertilizer specifically designed for Mostly Sativa strains with long flowering periods. Here are the dosage recommendations and instructions for use:
Dissolution measures:
- Concentration gr./Lt.: 0.5 - 1.5 grams per liter of water.
- EC (mS): 0.7 - 1.4 - 2.6 (These values are calculated with tap water at a medium hardness of EC 0.7).
Recommendations:
- For young plants and seedlings: Mix 2.5 to 5 grams of Mostly Sativa Powder Feeding in 10 liters of water. This range is ideal for the initial growth stages of the plants.
- During growth and flowering: Use 10 grams of Mostly Sativa Powder Feeding in 10 liters of water. This is the recommended range for the growth and flowering stages of your plants.
In soil:
- Alternate watering between using fertilizer and watering with water. This means that once you water with Mostly Sativa Powder Feeding, the next time you should only use water to water your plants.
In hydroponic or coco crops:
- Use the fertilizer at every watering. Every time you water your plants in hydroponic or coco systems, make sure to include Mostly Sativa Powder Feeding in the watering solution.
Recommended pH during flowering:
- Keep the pH in the range of 5.8 to 6.8 to optimize nutrient absorption during the flowering phase.
Important:
- Stop using the fertilizer 10 days before harvest. This ensures that no fertilizer residues remain in your plants at harvest time, which is essential for obtaining high-quality and flavorful buds.
By following these dosage recommendations and proper instructions for use, you will be able to make the most of Green House Powder Feeding Mostly Sativa and achieve optimal growth and flowering in your long-flowering Mostly Sativa strains.
