Add some material to the hydroponic bottle, the roots will be as thick as fingers, and the leaves will be green and glow

The most feared thing about water-growing flowers and plants with iron nails is iron deficiency. Once iron deficiency occurs, the leaves will turn yellow and the branches will become limp, which is really painful to look at. At this time, a simple small iron nail can release iron ions into the water, supplementing the necessary iron elements for flowers and plants. How to use: Be sure to prepare rusty iron nails, otherwise the intact iron nails will be difficult to oxidize in water, and if you want to replenish iron, you will have to wait until the end of time! Potassium permanganate Potassium permanganate actually has a disinfectant effect. Many people use it to wash the roots before potting. If the roots of your hydroponic plants are rotten, then they will have yellow or burnt leaves, and you will need to use potassium permanganate. How to use: Dilute potassium permanganate and water in a ratio of 1:500, then pour about 20 drops into the hydroponic bottle, stir evenly, insert the plants, pour out after a day, and replace with clean water.
If plants with ferrous sulfate are iron deficient, yellow leaves will appear due to iron deficiency, and we need to supplement them with iron in time. This is the case with the iron nails introduced above. But if you think using iron nails is too slow, try ferrous sulfate. How to use: Take 1 ml of ferrous sulfate and add it to 1000 ml of water, which is about the amount of two bottles of mineral water. Add 8 drops into the hydroponic bottle at a time, once every two weeks. Charcoal has the function of purification and preservation. Hydroponic plants often have root rot and stem rot, and charcoal can save them. How to use: Break the charcoal into fingernail-sized pieces and gently place them into the hydroponic bottle. Put 5 or 6 pieces in a palm-sized bottle. You can put more in the large bottle as appropriate! Remember to replace the charcoal with new one when changing the water.
Coarse sand hydroponics is most important for root health. Pour coarse sand into the hydroponic bottle to help the plants take root. This is the same principle as placing cuttings in coarse sand to promote rooting. How to use: Prepare coarser gravel, because fine sand or soil will make the bottle water turbid. Then sprinkle it gently along the wall of the bottle until it reaches a thickness of 3 cm on the flat bottom. Rooting Water Do the roots of your hydroponic plants have strong roots? If the leaves often turn yellow, it may be because the roots are too weak. In this case, even if there are a lot of nutrients in the water, the roots cannot absorb them. So if this happens, be sure to add some rooting powder. You can buy rooting water of excellent quality in Huahua Mall. Just click the original text below to buy it. Huahua highly recommends it! How to use: dilute 1g with 1 liter of water, add about 15 drops to the hydroponic bottle each time, and you will see significant results in one go. You can use it once or twice a week. Vitamin tablets If you have expired or damp vitamin tablets at home, such as vitamin B12, they can help plants take root, promote germination and leaf growth, and are also a good assistant for hydroponics. Directions: Crush the tablets and put one tablet in 2 liters of water. Stir well and use it up quickly, otherwise there will be a strong vitamin smell in the kettle. Finally, remember to use it once a month, not too frequently. If you feel that the plants are fine, you can increase the frequency and amount as appropriate.
You can mix the nutrient solution with a little flower fertilizer, such as common compound fertilizer, potassium dihydrogen phosphate, etc. If you find it troublesome, you can go to Huahua Mall to buy it. It is very cheap. Click the original text below to buy it. How to use: dilute at a ratio of 1g to 1 liter of water, and drop 7 or 8 drops into the hydroponic bottle. That’s all for today’s introduction. Do you know any other “magic tools” that can be put into hydroponic bottles?
