Extended Application Rate:
GROW – Fertilizer with Supplements – Soil/Soilless/Water Culture: Mix ½ tsp per 1.25 qt (2 ml per 1 L). Use as part of your regular fertilizer program during periods of green growth.
Fertilizer – Stand Alone – Soil/Soilless/Water Culture: Mix ¾−1 tsp per 1.25 qt of water (3−4 ml per 1 L). Use every time you fertilize.
As a suspension, this formula requires sufficient agitation prior to use. Each bottle of Impact Grow contains pure nutrients and has no added water. With this in mind, be sure to re-suspend nutrients prior to use to ensure top results.
BLOOM – Begin use 7-10 days before blooming.
Fertilizer with Supplements – Soil/Soilless/Water Culture: Use in conjunction with your regular fertilizer program to boost flower production. Early Flowering: Mix ½ tsp per 1.25 qt of water (2 ml per 1 L) Use as needed. Late Flowering: Mix ¾ tsp per 1.25 qt of water (3 ml per 1 L). Use as needed. Fertilizer – Stand Alone – Soil/Soilless/Water Culture: Mix ¾−1 tsp per 1.25 qt of water (3−4 ml per 1 L). Use every time you fertilize.
