Preparation of nutrient solution for hydroponic Flower

Liquid A: 125g of calcium nitrate, 12g of ferrous sulfate + liquid B: 37g of magnesium sulfate, 28g of ammonium dihydrogen phosphate, 41g of potassium nitrate, 0.6g of boric acid, 0.4g of manganese sulfate, 0.004 g of copper sulfate and 0.004 g of zinc sulfate. You can also buy flower fertilizer or compound fertilizer and add it to the water after dissolving.

Common preparation

Required materials

Liquid A: 125g calcium nitrate and 12g ferrous sulfate. Add the above to 1 kilogram of water.

Solution B: 37 grams of magnesium sulfate, 28 grams of ammonium dihydrogen phosphate, 41 grams of potassium nitrate, 0.6g of boric acid, 0.4g of manganese sulfate, 0.004 grams of copper sulfate and 0.004 grams of zinc sulfate. Add the above to 1 kilogram of water.

Preparation process

1. Weigh all kinds of fertilizers and put them on clean containers or plastic film bags, as well as plastic film bags spread flat on the ground.

2. When mixing and dissolving fertilizers, strict attention should be paid to the order. Calcium nitrate should not be mixed with several fertilizers other than potassium nitrate, such as magnesium sulfate and ammonium dihydrogen phosphate, so as to avoid calcium precipitation.

3. In the order of fertilizer dissolution in pot A, ferrous sulfate is dissolved in warm water, and then calcium nitrate is dissolved, stirring while adding water until evenly dissolved; in pot B, magnesium sulfate is dissolved, then ammonium dihydrogen phosphate and potassium nitrate are added in turn, and water is added until completely dissolved. Boric acid is dissolved in warm water, and then the rest of trace element fertilizers are added respectively. Two kinds of liquid tanks An and B are stirred separately and then set aside.

4. When using nutrient solution, take 10ml of A tank mother liquid and dissolve it in 1kg water, then add B tank mother liquid to this 1kg water, then you can use it.

Simple method of preparation

Some flower friends may be dizzy when they see so many numbers and the kinds of fertilizers. Don't worry, netizens have also provided their own experience, so you might as well give it a try.

High efficiency flower fertilizer method

Buy a bag of efficient flower fertilizer at the flower market, add water to clarify, and then pour it into a large bottle. Be careful not to pour too much in hydroponics, just add a few drops to the plant at a time.

Compound fertilizer preparation method

Every time the water supply plants change water, you can add 4 or 5 grains of compound fertilizer to the water, netizens test the effect is good.

Of course, the specific amount of use depends on the size of the plant and the size of the flowerpot. Be sure to remember that when preparing nutrient solution, do not use metal containers, you can use glass, ceramics and other utensils.
