Key insights about video Gardening with Rik: How to make Hydroponic nutrients

🔍 The optimal NPK ratio for growing onions hydroponically is 150-150.

🌱 A nutrient called Ultra Green, with a ratio of 23-6-10, is commonly used for lettuces but is too low in concentration for onions.

💦 To achieve the desired NPK ratio, a chemical called mono ammonium phosphate can be added.

⚖️ By adding mono ammonium phosphate, the final NPK ratio for hydroponic onions can be adjusted to 150-97-60.

🌿 It's important to remember that the initial ratio of 150-100-50 was used for onions grown in soil.

🔬 The NPK ratio for hydroponic onions can be adjusted by dividing the concentrated solution with mono ammonium phosphate.

⏳ The final adjusted NPK ratio for hydroponic onions is 37.5-24.25-15.

Timestamped Summary

01:56 The narrator explains that the optimum NPK ratio for growing onions is 150:150.

02:26 The narrator introduces a nutrient called "Ultra Green" with a ratio of 23:6:10, but notes that this ratio is too low for onions.

02:58 The narrator suggests multiplying the concentration of "Ultra Green" by 6 to achieve an NPK ratio of 138:36:60.

03:16 The narrator introduces another chemical called "Monobasic Ammonium Phosphate" with an NPK ratio of 12:6:1.

03:47 Combining the "Ultra Green" and "Monobasic Ammonium Phosphate" will give a ratio of 150:97:60, close to the desired ratio.

04:15 The narrator explains that the concentration needs to be reduced, and decides to divide the numbers by 4, resulting in a final ratio of 37.5:24.25:15.

04:56 The narrator shares that this will be the ratio used to grow the onions in hydroponics.
