Can you substitute a lamp for sunlight when growing indoor plants?

You have to use a grow light like this one

YES you can!!! This is the one that I’ve used with great success. This one is NOT currently available, but the specs might help you to find a good one. The “red/blue spectrum” is very important!!! There are 3 at the very top of the page tht has the right specs that will most likely work but I can’t verify them. I also learned when I was about 25 that you could use 1 red & 1 blue fluorescent light bulb & get the same effect for a LOT LESS money. That works great in an office where you have the light fixtures already in place & your eyes won’t see any difference.

My dad grew a jungle in our basement using grow lights.

Special pink lights are best from what I understand.

Yes, but there are also many houseplants that thrive in low light.
