If you want to ensure rapid growth of your vegetable seeds indoors, then using grow lights can make all the difference. Get advice on which plants benefit from starting indoors and how to use grow lights.

If you are planting seeds indoors, then your seedlings must have strong light once the first leaves have emerged. Otherwise, they will get leggy and weak, a sure sign they are not getting enough light.

If you have ever grown seeds on a not-so-sunny windowsill or too early in the season, then you have seen how seedlings get tall and spindly and sometimes flop over. In many areas, the winter sun is simply too weak to provide enough natural light. 

Grow lights provides strong light to start healthy, vigorous, fast-growing plants. They provide light from directly above which promotes strong, upright growth. This is different than a windowsill where light is from the side. 

There are many different grow lights on the market. See our post on what kind of grow light to buy.

Vegetables for Grow Lights

Some crops should not be started indoors—such as root vegetables (which do well outside in the cold, anyways). 

However, many vegetable seedings are perfect for starting indoors. Here are our favorites:

  • tomatoes
  • peppers
  • cauliflower
  • chili peppers
  • squashes
  • broccoli
  • melons

Many of these vegetables require a long growing season so starting them under grow lights will give them a nice head start.

Growing lights article is in video form and that video does not work. Please fix.

Hi Kay, The video is indeed working and has been tested across platforms, so this is probably related to the computer set-up. If you are using Chrome, it might be necessary to clear the cache which you do by going to the Settings menu (three dots icon) > More Tools > Clear Browsing Data and then restart Chrome.

Not sure if they fixed it but it is working for me this morning 2 - 18 -17. I am on my laptop and just thought I would let you know that often videos don't work on my Kindles. Maybe it is the device you are on. I have no technology skills so don't know why some of these work and others don't but wanted to share my experience with you in case it helps.
Happy Gardening!
