The best thing about potatoes is that they are a good source of nutrients and you can store them for a long time without much effort.

Potatoes Seeds

You can start growing potatoes indoors from potato seeds. You should buy high-quality potatoes seeds to grow them at home.

Buy potatoes that have small spots on them. These spots are called the eyes of potatoes. This is the part that germinates and one potato with 6 eyes can give you near about 2 lbs of healthy potatoes.

If you do not find potatoes with eyes in the supermarket do not worry, I have a solution for this.

Buy healthy potatoes and leave them near a window for a few days until they develop small sprouts.

Once they Sprout you need to wash them with a vegetable brush. In case you don’t have a brush, wash them under running water and lightly scrub them to remove dirt and another residue. Be careful around the eye of potatoes to make sure they don’t get damaged while washing.

Potato Germination

First of all, take a potato with eyes and cut it into two pieces. Place your potato on a table and cut it from the middle. While cutting them do not cut potato eyes.

Because this is their germinating part.

Now put the 4 toothpicks in the potato as shown in the figure. The purpose of these toothpicks is to hold the potato when you put it on top of the glass of water.

Submerge the potato half into the water as shown in the picture. Now place this glass of water with submerged potato under the grow light or south-facing window.

At this point, you need to give 6 to 7 hours of light per day. After 7 to 10 days, you will surely see the new roots coming out of the potato.

Soil and Container for Growing Potatoes Indoors

For home gardening, you can use plastic-made containers they are easy to move from one place to another and cheap to buy.

Just make sure every container has one drainage hole at the bottom. This hole is there to protect your plant from accidental overwatering.

If you give more than enough water to your plant the extra water will drain out of the container through this darning hole.

Put small stones or pebbles at the bottoms of the container. This action will protect your plant from root rot and mildew.

To get a high yield you should use a container that has 9.5L of capacity.

Fill one-third of the container with potting soil. The soil should be loose and high nutritious. The pH of the soil should be between 5 to 5.7.

If the soil pH is high, use a Soil acidifier also called elemental sulfur to adjust it to near 5.4.

In the next step place the potatoes in the pot with roots facing down into the soil. The longest sprout should be facing toward the ceiling.

Now cover the potatoes with 2 to 3-inch-thick layers of soil.

Light for Indoor Growing Potatoes

Potatoes need a good amount of light for 8 to 12 hours per day. The light source can be sunlight or artificial man-made grow lights.

If you can give sunlight to your potatoes for 8 hours then you do not need to buy grow lights. You will harvest a huge number of potatoes in the end.

But if sunlight is not sufficient then you definitely need a grow light.

In fact, it is best to buy a grow light for indoor growing potatoes. Moreover, if you can afford a grow tent you can grow any vegetable at any time of the year.

Because grow tents give you full control over the vegetable growth. You can control the internal environment of the tent.

600 watts of LED grow light is enough to use for growing potatoes indoors and many other vegetables and salad items.

Water requirements of potatoes

At the initial stage keep the soil moist and spray water once every 2 to 3 days. After week 6 you must increase the water applications.

Because now potatoes are in the second stage of growth and need more water to grow large in size.

Avoid overwatering the plants because this will only result in potato fungus. always check the soil conditions before watering them.

If the top 2 inches of the soil are dry then immediately give some water to your potato plants. They must be clean and do not contain heavy minerals.

In some parts of the country tap water is not suitable for drinking. You must not use such water for watering indoor growing potatoes.

Cut the water supply 15 days before the harvesting time. This will help the tubers to dry and curve.


Indoor growing potato plants need fertilizers once in 30 days. Use any balanced liquid fertilizer that has a bunch of organic content.

Stop feeding your plants 14 days before the harvesting time.

For feeding take the appropriate amount of liquid fertilizer and mix it well in water. Then pour it to the base of the plant.

Adding Soil

Add more soil to your container as the potato plant grows in height. Because when the potato vine grows it produces potatoes. Potatoes need sunlight to fall on the foliage.

So, by mixing more soil you can encourage your plant to grow more in height and produce more potatoes.

Harvest your Potatoes

After 10 weeks you can harvest your potatoes. If you cannot remember the plant age don’t worry wait until the foliage gets to die.

Whenever the foliage begins to die, stop watering it, and after 7 days harvest your potatoes.

Give water to your plant to loosen the soil and after 30 min take the plants out of the container. Collect the fresh potatoes with your hands (wear garden gloves).

Leave the potatoes as they are for 3 hours to harden the skin.

This process will save them from many diseases and you can store them for a long time.

Store Harvested Potatoes

The good news is you can store your potatoes for 5 months in a cool and dark place. keep the temperature between 8 to 14 degrees C.

You can also store your potatoes in the refrigerator in the vegetable tray but for only 1 week. Because after 7 days the starch in potatoes starts converting into sugar so use them within 7 to 8 days.

If you are storing them in your fridge.
