Growing Jalapenos Indoors


“I’m wanting to grow my own jalapenos. I was curious about indoor growing in a large pot. Would jalapeno plants thrive as an indoor plant, assuming a good, sunny window?

Michael”

Hi Michael,

Thank you for your email regarding growing jalapenos indoors.  To be honest, given the conditions that you are planning to grow them under (in a sunny window), I would not recommend it.

First of all, I don’t want to say that it won’t work.  It’s just that you will have some problems in terms of light and you will probably not have a great crop of peppers.  The reason why I am hesitant to recommend this method is because of the composition of window glass that is found in most homes.  Glass that is found in greenhouses is very basic and allows for all solar rays other than UV to go through.  However, windows used for homes have glass that is a little bit more high tech and blocks more than just UV rays.  Because these other types of rays are blocked, the plants in your
home sitting by the window do not get a full spectrum of light.  For some, like a pathos or a philodendron, that is fine because they are used to filtered light in their native outdoor environments.  But for peppers, that’s not good because they are accustomed to having full, direct sunshine.

What you would see happen is that your stems would become elongated between the nodes where the leaves and branches come out.  Also, the color would be lighter than normal.  Not having the optimal conditions would eventually reduce the amount of buds set and/or the amount of fruits set.

I admit, I have brought bell and habanero type peppers into my home that were grown outside before frost and were brought in to finish things up. They did okay, but only because it was for a couple of weeks.

I don’t want to discourage you from growing peppers inside, but I want to make sure that you are aware of what they need so that you are not disappointed.  What I would recommend doing is growing them under a grow lamp.  Unlike the rays allowed through the window into your home, a grow lamp will provide the full spectrum of light that will be needed for the plants to have normal growth rates.  It can be the same type that you use to start seedlings in spring, but just make sure that there is enough room under it to allow the jalapeno plants to grow to their full height.  Keep
the grow lights about 1-3 inches above the tops of the plants as they grow so the light is not too diffuse.  You can leave the lights on for 18 hours a day.

I hope this information helps you out.  If you have any other questions, please feel free to ask.

  1. Wow… I must say that your response is the most thorough I have received from the places I have inquired about growing jalapenos. Thank you.
    I was wondering about the varieties of jalapeno peppers you have and how well that these would grow here in Iowa and in a large pot (outside) instead in the ground?

    • Thank you for the compliment. I appreciate it. =)

      As for jalapeno varieties, the one I recommend hands down is our Goliath Jalapeno (Tula F1) Hybrid. It has a really well developed flavor and a lot of heat, but not so much that it would be overwhelming. Plus, you can also taste the pepper in addition to just the heat – I find that it works well when using them for salsa, scrambled eggs/breakfast burritos, pickled peppers, etc.

      If you want to go with more an heirloom type, then I recommend Early Jalapeno. It has a good flavor too.

      Both of these varieties would work well in Iowa. And also, other varieties will too.

      Again, thank you for the comments. If you have any other questions, just let me know.
