Onion sprouting can be put into the container water culture, and it is easy to germinate, it is best to use rainwater or river water breeding. Onion aquaculture planting methods: processing onions, poor growth and messy parts of the excision, into a good choice of appropriate containers; water and fertilizer management, according to the different growth period of the water, you can add the rooting powder to accelerate the growth; light temperature, daily to maintain 4-6 hours of light time.

Onions can be put into containers of water after germination, and it is easy to germinate. The best use of rainwater or river water breeding water, when the onion grows root logistic water, and put it in the light ventilation, every day to give the onion enough light time, so that it can make it grow healthily.

1, processing onions

Choose a large, preferably close to the germination of the onion bulb, will have rotted off the epidermis for the removal, and with a clean knife to cut off the bottom of the growth of the poor or too much disordered rhizome, can better absorb the water. For better water absorption, pick a container with a mouth slightly smaller than the onion's and add water, just enough to touch the bottom of the onion.

2, water and fertilizer management

The early stages of aquaculture need to be diligent in changing the water, usually once a day, about a week or so you can see the new growth of the roots, and to be grown after the new roots, you can reduce the frequency of water changes, every other day and then change the water until the top of the green shoots. After the change to 3-4 days once, you can add rooting powder to accelerate the growth of onions during the growing period.

3, light temperature

water need to be placed in the position of light ventilation, onions like to grow in the environment of 13-22 ℃, in the maintenance of the initial period, you can see less light, to be grown after the new leaves, to provide sufficient light, light on the roots! Favorable, keep 4-6 hours of light time every day, can effectively accelerate growth.
