Plants grow well in a wide range of hydroponic nutrients. Plant nutrients used in hydroponics are dissolved in the water and are mostly in inorganic and ionic form. They contain cations (positively charged ions) like Mg2+, Ca2+, and K2+ whereas anions (negatively charged ions) present are So4–, No3-, and H2PO4-. These charged ions provide equilibrium to the solution and help in better growth of plants.
In indoor gardening, plants can be grown in hydroponics nutrient solution in water or any other inert medium such as coco coir or rockwool or perlite. Organic nutrients help in healthier growth of plants. These nutrients are specially formulated to meet all your plants’ needs. Another advantage is that most of the nutrients must be dissolved in water and then supplied to the plant. Some hydroponic nutrients help in overall growth of plants while others are focused on specific parts such as fruits, flowers etc.
Let’s have a look at some for the best suited nutrient solutions for indoor gardening:
- Bloom Boosting Nutrient Solutions: In hydroponics, growers concentrate on their final product which is often either fruit (tomato, apple, strawberries etc) or flowers (lilies, roses etc). These parts of the plant require extra nutrients for healthy growth. Bloom boosters are completely organic and promote intense growth of the vegetation zones of plants. Nitrogen is the main nutrient supplied by these solutions, as well as limited amounts of other micro-nutrients.
- High Impact Hydroponic Nutrients: These nutrient solutions are often used in drip irrigation system of hydroponic indoor gardening. High impact nutrient solutions have macronutrient such as nitrogen, phosphorus and potassium. These nutrients along with calcium, sulfur and magnesium are required in doses to help the plants develop firm cell walls, fight off disease and infection, and give the plant enough energy to mature into a bloom or fruit. Another advantage of these solutions is the ability to test the pH of the solution when mixed with water on the basis of color.
- Inorganic Nutrient Solution: Many hydroponic growers prefer inorganic nutrient solutions because organic nutrients require some time to decompose before they can impart their nutrients to plants. This changes the amount of nutrients being fed to a plant during feeding, since decomposition of the material happens at variable rates. Inorganic chemical compounds such as dietary minerals, water, and oxygen form these nutrient solutions and help in flourishing growth of indoor plants.
Remember that the right type and amount of nutrient solution along with the best medium, appropriate lights and controlled atmosphere inside the grow room will help you get the best yield.
