Usage Rates
While HGV does not provide a "feeding chart," our baseline recommendation remains a 3.0 EC from clone to harvest. Since every facility and room have unique variables, adjustments will be necessary depending on how you manage plant growth. Additionally, water sources vary regionally and globally, so our usage rates may fluctuate based on the elements present in the water.
Our cultivators typically achieve the best results with a pH of 5.7 and an EC of 3.0, whether using rockwool, coco, DWC, or NFT. Plant health will dictate the ideal EC in relation to your environmental strategy. When using LED lighting, we typically observe a 10-20% increase in feed strength, whereas under HID lighting, we usually maintain a 3.0 EC.
In soil, feeding strategies depend on soil analysis, whether growing in-ground or in large pots. Through soil analysis, our team can develop a tailored feeding strategy for the season and provide precise consumption predictions and annual spend forecasts. Contact us to learn more.
That said, HGV performs well across various growing media and conditions. The key focus should be on environmental and irrigation strategies, as these two factors are the primary causes of plant health issues. In fact, 9 out of 10 times, plant health concerns are attributed to environmental stressors.
For HGV, we recommend a 60/40 or 0.6:1 ratio. For every mL (or gram) of Grow or Flower you adjust, you should increase or decrease the Base by 0.6mL (or gram).
We advise against following a 1.2 EC or 1.8 EC reading with our products, as nutrients are non-cumulative. For example, if one input reads 1.2 EC and another reads 1.8 EC, the combined result will typically range between 2.5-2.7 EC. To maintain the correct ratio, divide the HGV Base by the Grow or Flower ratio (e.g., 18/30 = 0.6). This ensures proper mixing. In a final 3.0 EC solution, separating the inputs will likely result in 1.4-1.6 EC for Base and 1.8-2.1 EC for Flower or Grow.
At HGV, we live by the principle of “Trust but Verify,” so we recommend conducting a nutrient analysis to confirm elemental levels. Our Nutrient Experts review these results daily and are available to assist with any questions. Contact us to learn more about sampling and test reviews.
