Indoor Pepper Growing Kit

One of the biggest issues most people face when growing peppers plants indoors, or any vegetable, indoors is creating the appropriate growing conditions. If you can replicate their needs inside the house, you can successfully grow peppers indoors.

Before growing peppers indoors, consider these few items because having a proper setup can enhance your indoor gardening experience.

  • A dedicated area to grow your plants: You can choose to put them on the floor and hang the lighting above them. But it will be easier on your back if you invest in a table, shelve, trunk, or any other flat surface to give your plants a place to sit.
  • Grow lights: To grow hot peppers successfully indoors, you need to give them enough light, according to the University of Texas at Austin experts. Insufficient light leads to your plans being leggy and weak. In most cases, you might need a grow light when growing peppers indoors, unless you have an indoor sunroom or other extremely well-lit spaces in the house. Some pepper plants are easier to grow in low light, including Thai Pepper, which can produce loads of peppers for you even under a T5 fluorescent shop light or compact fluorescent (CFL) grow light. However, other pepper plants, including jalapenos, will not give you many peppers, even if they have tons of foliage. 
  •  Grow mat or a heating pad: It helps provide the warmness your pepper plants need without heating your whole house. While a heat mat underneath the plants will also provide warmth, placing grow light about 3 inches (7.62 cm) above the pepper plants will raise the temperature by about 10°F, according to The Brooklyn Botanic Garden.
  • Container: Ensure that it is sufficiently large to support your pepper plant and drains well. The size of your container depends on your available space, the type of chili pepper plant you want to grow, and how big you want your pepper plant to be. Because generally, different chili peppers react to container sizes differently. For example, the Jalapenos pepper generally provides fewer pods when constrained in a small pot (1 gallon or smaller). Like the Thai Dragon, Thai varieties can still produce loads of peppers even in a smaller container.

Tips For Growing Pepper Plants Indoors

  • Remember that indoor pepper plants need the same requirements as those grown outside. They need sufficient space in a container for their roots to grow. They need plenty of sunlight; ideally, place them south- or west-facing window, according to the The Brooklyn Botanic Garden.
  • Peppers plants need full sun. If you don’t have adequate light available, use a grow light because peppers like it warm; how warm depends on the pepper variety. Generally, ornamental chili peppers plants thrive in lots of sun and moderate humidity.
  • Habaneros prefer mild temperatures and high humidity.
  • Most hot peppers thrive in cooler nighttime temperatures and do not do well in hot or cold drafts.
  • Peppers require growing temperatures of about 80-degrees Fahrenheit (26 Celsius) during the day and 70-degrees Fahrenheit (21 Celsius) at night. You may not be able to keep these temperatures at these levels, but if you can maintain them within a 20-degree range, your plants will still thrive.
  • You can boost the temperature by placing the plants under grow light or on a heat mat, without you requiring to raise the temperature in your entire home.

What Month Should You Start Pepper Seeds Indoors?

The best time for planting pepper seeds indoors is about 6 to 10 weeks earlier than transplanting, which ought to be finished 2-three weeks after the anticipated final frost. Most pepper seeds sprout approximately every week at a temperature of 70-80 degrees F so mid-march is the most suitable time because it gives the finest temperature and all necessities are met.

As hot peppers can be very finicky germination can be spotty depending on the variety here is a little tip to avoid surprises:

Providing about sixteen hours of light for your pepper plants will encourage them to start or continue thriving indoors. Try to give them as much natural light as possible and then supplement the remaining hours with a grow light.
  • Consisting watering the plants properly: Pepper plants, particularly hot peppers, need to dry out between waterings but ensure they get at least 1 inch (2.54 cm) of water each week.

How Many Pepper Seeds Per Hole?

Use the germination rate information for an individual plant to calculate the optimal number of seeds for what you’re planting. Just make sure when you’re using new or clean pepper seeds, you may plant one in a hole.

  • If you’re using aged seeds that have a low viability rate, then plant two-three in the hole. If multiple germinate, thin out the weakest when they have 2-3 sets of genuine leaves.
  • If you place more seeds than needed competition for sunlight, water, and minerals increase, and requirements are not met. It is possible that only one seed will sprout and may wilt shortly due to no proper nutrition so placing multiple seeds is not optimal.
