Growing Hot Peppers Indoors

Winter is still upon us, but this has no bearing on your ability to grow delicious hot peppers in the comfort of your own home. Whether you are growing indoors from sprout to harvest, or simply starting off your seeds for the outdoor season, both can be accomplished with great success.

In part one of this series I will discuss the best methods used for sprouting your pepper seeds. Although it is possible to sprout your seeds in soil, we will be focusing on the hydroponic methods in order to take advantage of the many benefits of hydroponic growing. These benefits include increased growth rates, faster maturity and fruit production as well as increased yields.

The first step in sprouting pepper seeds is to give them a presoak. This means you should soak your seeds in water overnight to kick start the germination process. A shot glass or similar device works well for this practice. Remember to separate seeds based on variety in order to be able to identify which plant is which down the road.

The next step is to prepare your growing medium. Jiffy 7 propagation plugs are best suited to soil or soilless growing as they have fine particles which can become loose and clog or soil active hydroponic systems. Rockwool starter plugs can be easily transplanted to either soil, soilless or hydroponic gardens making them the most versatile. Both of these types of growing media require a presoak before they are ready to receive the seed. Using your pH tester and your pH Down, set the pH of your water to 6.5 for the Jiffy 7 method or 5.5 for the Rockwool method. Do this by first testing the pH of your water and then adding a few drops of pH down and retesting until your pH is in the correct range. Be sure to stir the solution well before taking your adjusted pH readings.  Once your pH is set to the correct level, it is time to soak your media. 10 seconds is sufficient for Rockwool and the Jiffy 7’s will require more time to expand since they come in compressed form. Once your media is soaked it can be transferred to your propagation tray. The Jiffy 7’s will require some shaping and removal of excess water before they are placed in your propagation tray. Propagation media should be moist but not soggy or else your seeds may rot.

Now that your tray is full of propagation media, it’s time to insert your presoaked seeds. Best practice is to place three seeds per propagation plug. If your seeds are far more valuable than the cost of the propagation media, you may elect to plant only one seed per plug. Seeds should be planted at a depth of 1/4? and tamped gently to ensure coverage. Sometimes it is necessary to tear off a small piece of Rockwool from the edge of the cube to cover the seed. Once seeds are planted and tamped, they are ready to be sealed in their propagation dome to establish a warm humid environment to aid in germination. A Seedling Heat Mat can help speed up the germination process, however, be sure that the media does not dry out due to the added heat (ideal seed temperature for germination is 80-85 Degrees Fahrenheit).Ensure that there is no standing water in the bottom of your tray and then the propagation tray/dome can now be placed in a sunny location or under a grow lamp to speed up the propagation process.

A general rule of thumb is that a single T5grow lamp can be sufficient to sprout seeds, however, multiple lamps will produce better growth once germination has occurred.

Suggestion: Coloured small paper clips make for excellent plant identifiers. Other low cost items can be used as well, just be sure that they do not absorb moisture such as wood or paper or they will be prone to grow mould while sealed in your propagation dome.

Note: some pepper seeds can take up to 4+ weeks to germinate.

Once your peppers sprout and begin to grow, the strongest of the three seeds should be left to live, and the weaker plants culled from each propagation plug. This can be achieved by simply clipping the weaker plants with a pair of scissors at the base. It is not recommended to grow more than one plant per plug as they will compete for resources for the rest of their lives. Also at the time of germination, the vents on the propagation dome should be progressively opened each day to slowly expose the seedlings to the less humid atmosphere. Once the first set of true leaves appear (not the first set of rounded leaves called cotyledons) it is time to apply your fertilizer at 1/4 strength. For DNF Gro this means 1.5 ml of part A and 1.5 ml of Part B to one litre of H2O. Only water once plugs become dry and light weight, however do not wait too long for your delicate sprouts to wilt or the damage may be irreversible.

Congratulations, if you made it this far then you are well on your way to producing a healthy pepper harvest!

Stay tuned for the next installment which will focus on the lighting and growth methods available to grow these sprouts to the size required for an abundant harvest!
