Hey, so I remember we had a hydroponics thread a while ago, and it's the season...
First off, to get the jokes out of the way... no, not everyone growing plants indoors is growing drugs
Right now I have a bunch of cacti, bamboo, a few poppies germinating, this weird palm tree kinda plant my friend gave me, and an amaryllis that I think is infected with some kind of fungus. I've also planted a bunch of cactus seeds, so we'll see how that goes over the next couple of months.
For light I have 3 42 watt CFLs (each is a 150 watt equivalent) and I have most of the surfaces of my closet covered in aluminum foil to reflect light onto the plants. I'm running an 18/6 cycle.
I also have shiitake mushrooms which are incubating. I'm not that knowledgeable about growing plants but I have a little more experience with mushrooms, and I'd love to answer any questions you guys have about growing them. If you follow the steps, you can pretty much count on pounds and pounds of them. I'm also going to grow Oysters soon, I haven't had those in a while. It's very different from growing plants, for sure... and not too many people know how to do it.
So question to the experienced indoor growers: Do you think it's worth it to upgrade my lighting? I think a 250 watt HPS light would be fantastic, that would put me from about 8000 lumens to over 30,000, and I wouldn't be using more electricity since I'd be running it for fewer hours than the inefficient CFLs. I'm thinking run the CFLs 4 hours, the HPS for 10, and the CFLs for another 4.
As I understand it, if I want to grow fruits/vegetables indoors, I will need to upgrade to HPS.
