Hydroponic is a farming method where we don’t need to use soil as the planting medium. Napa cabbage is an up and coming vegetables originated from China and luckily, you can grow this hydroponically.
Here’s how to grow hydroponic napa cabbage easily:
Tools and materials
- Used plastic bottles, a knife or a pair of scissors, nails
- Rockwool as planting medium
- Water, topsoil, compost, hydroponic nutrients
- Wick, which you can make from twisted flannel or cotton
Step by step
- Cut your rockwool into pieces, then wet them with water, and put them on the tray.
- Put one or two napa cabbage seeds per rockwool.
- Put the train in a dark area or cover it with a lid. Your seeds will germinate in 24-48 hours.
- Once your seeds have germinated, open the lid or move your tray to a well-lit but still shady area.
- Spray some water to your rockwool twice a day, in the morning and the evening.
- Prepare your plastic bottle, nail, and scissors. Cut your bottle in half and make a hole at the end of each part using the nail. The hole should be in the size of the wick.
- Put the wick in.
- Fill the half bottle with a piece of soil humus.
- Fill two thirds of the bottle with water and hydroponic nutrients. You can also spray hydroponic nutrient directly on to the plants once or twice a day.
- Make holes in the humus about 1 cm deep, and then move your napa cabbage seedlings into the holes carefully.
- Pay attention to the amount of water, the pH level, heat contact, and the growth rate of your hydroponic napa cabbage.
