Well, instead of building a dedicated structure I've decided to instead start my seedlings in the house. Don't tell my wife, she doesn't know it yet. Anyway, I have numerous (4) foot shop lights in storage and I was wondering what tubes I should use? I'm not really a cheap person but money is rather tight these days so I don't want to spend a fortune if I can help it. I know they do have grow lights available, are these better than regular tubes? BTW...I've always direct seeded so that's why I'm not familiar with propagating under lights. Thanks!
