How to Grow Beans Indoors:

Step 1: Select the location for growing beans

Choose a place with at least 6 hours of sunlight per day. This way the plants will receive enough light to grow properly.

Step 2: Preparing the soil

First, add a layer of mulch to the soil, because it helps keep the soil warm. Next, make sure the soil is well-drained and evenly moist. You may want to add some pebbles or sand to the bottom to help this.

Sow your bean seeds into the soil, about two to three seeds per inch (5-8mm). Water them first, then cover the pot with plastic wrap.

Step 5: Moisture

Keep the soil moist, but not wet.

Step 6: Let the seeds grow for about 7-9 days

Remove the plastic wrap, and water if necessary.
