Is there a particular type of fertilizer for growing herbs and vegetables indoors?

Asked January 19, 2019, 4:53 PM EST

I'd like to grow lettuce, chard, and other foods indoors throughout the year. I want to be clear on what type of fertilizer to use. I only see information for house plants; does it matter that the plants I'm interested in are for food use?

You can use any balanced fertilizer for vegetables (for example, liquid fish emulsion and seaweed is an organic option with 2-3-1 NPK). Follow the label directions. Both chemical and organic fertilizers, if over-applied, can burn plants.

Perhaps more importantly, make sure you have a system set up for your plants to get a sufficient amount of light. Lettuce seedlings, for example, need 14-16 hours of light daily placed 2-3 inches above the seedlings.
