First and most important, fruiting plants require pollination. We doubt that you will have bees buzzing around in your home, so pollination has to occur by hand. This is best done by using a small paintbrush. Simply brush on the flower and then brush on other flowers to pollinate them.Growing fruit requires a lot of energy both in the form of light and in the form of nutrients. If you have pollinated the flowers and no fruit are growing (most often this goes along with yellowing of leaves which means that the plant has a nutrient deficiency) it is recommended to increase the fertilizer dosage to 4mL – 5mL of fertilizer per liter of water. It is also recommended to have the light duration set to 16 hours per day at maximum light intensity setting.
