Also it is best sown into any of your individual cells, pots or cubes as the seedlings does not suit to transplant in order to propagation. You might be waiting for only five days to observe germination only if the temperature is about to 70-80 degrees F.
At the same time, cilantro seeds will take approximately 7-14 days to germinate as they are quite hard coated. When the sprouts appear, transplant them into a hydrophone system. Don’t worry if the seedlings seem to be growing slowly at the beginning, they will prove a rapid growth after they are provided adequate nutrients through water.
If you want to enjoy the greens for a long time, avoid bulk of them at the same time sowing a lot of seeds at once. Instead, maintain a sequel. Maintain a gap of one or two weeks for sowing. This will allow you harvesting for a long time.

Harvesting your coriander
It depends on the grower when he’ll harvest it as all the parts of the plants are use-able. So, the time of harvesting it for leaves defers from the time for seeds and flower. We must focus on the time that suits best for leaves. In this cause, you can harvest it from the seedlings as micro-greens to mature plants especially before it starts flowering. The young plants have a mild flavor to enjoy while the matured one may be bitter and you might not like it as many of the gardeners do.
Cut your fresh cilantro freshly and use it within a few hours. Otherwise they might wilt. If you are going to store some of them for later application, store it at 32 degrees F being packaged in a plastic bag. After harvesting for current usage, if you think it will take several hours to use them, you can place the stems into a glass of water avoiding storing in refrigerator for a short time.
While you are opting to grow some hydroponic cilantro, you may face with some problems specially with two – bacterial leaves and powdery mildew. When the leaves are affected by bacteria, they result in some yellow spot on them. It happens only because of the excessive moisture or high humidity of the growing area.
The second one i.s powdery mildew is nothing uncommon as indoor pest and you can easily identify it by a powdery film that is white in color. To fight against this disease, ensure the proper temperature of your growing area. Also you won’t hesitate to weed out the affected seedlings soon after you identify the spot on the leaves. Some spray may be applicable if the attack is acute but before applying chemical, you are highly recommended to consult with an expert or an agricultural officer.
Again you might face with root rot. It is caused by inadequate oxygen at the root. Install an aquarium air stone in your hydroponic system or apply an air pump instead.
In cause of putting the system outdoor, the plants may also be affected by white-flies. They are very quick and can easily be everywhere on the plants. Treat quickly. Apply a dose of neem oil or such a spray that contains neem oil. Hope it’ll do enough to break the cycle of the pests.
