Plants grown traditionally in the soil could get essential nutrients form the soil, but if you’re growing using a hydroponic system, it would be up to you to ensure that everything your plants need is in the nutrient solution. You could choose ready-made hydroponic nutrients concentrate and simply add a certain amount of water. It is also a good alternative to make a simple, inexpensive hydroponic nutrient solution on your own using some basic ingredients.
Here’s how: www.nutritionlines.com
1. Pour just enough water into a tank, tub, bucket or other container to fill the nutrient reservoir for your hydroponic system. Make sure you measure the number of gallons.
2. Check the pH level of the water you’ll be using in your nutrient mixture, using a pH test kit for hydroponic systems. You can get this kit from hydroponic stores and suppliers. The pH level must be between 5.0 and 6.0. If the level is beyond this range, use the chemicals in your kits to adjust the pH level down or up, until it’s within that range.
3. Measure two teaspoons for every gallon of a complete dry fertilizer that is soluble in water. Use a fertilizer with macro nutrients like magnesium, sulfur, potassium, nitrogen, phosphorous, and calcium. Also, make sure that it contains essential micro nutrients such as boron, zinc, chlorine, cobalt, manganese, iron, copper, and molybdenum. Then add this fertilizer to the water.
4. Add one teaspoon of Epsom salts for every gallon of water.
5. Mix all dry ingredients in the water until all crystals and powder dissolve in the water well.
6. Remove and then replace your nutrient solution every one or two weeks to make sure that the plants will have a continuous supply of the nutrients they need.
If your reservoir in your hydroponic system holds plenty of water, mix one or two more batches of hydroponic nutrients.
Never overfill the container, otherwise the hydroponic nutrients will spill as you mix them. Use the solution immediately after mixing, since they could lose some of its strength when you store it before usage.
If the level of the water drops between changes because of absorption or evaporation, use just plain water to replace what’s lost. Adding a new batch of nutrient solution to the old could cause an imbalance and salts which could harm plants can build up.
This type of fertilizer is best used in ebb-and-flow hydroponic systems, hydroponic raft setups, and other hydroponic systems that do not tend to clog. Hydroponic systems like aeroponics or drip hydroponics could clog if solids reach the nozzles.
