Warm vs cool? "Full-spectrum?" LED, CFL, or HID? Here's what you need to know about mars grow light for starting seeds, gardening inside, or houseplants.

Indoor growing offers many advantages. The biggest benefits are the most obvious: garden pests can’t get at your plants, and you have total control over the weather.

Yet unless you’re lucky enough to have a solarium or greenhouse attached to your home, providing sufficient light to your plants will likely be an obstacle (shade-tolerant houseplants excepted).
