I've heard that LED isn't there yet for growig, which surprised me. I used the hood of an Aerogarden. It worked well enough to grow a jalapeño from seed. It grew forever and wouldn't flower. Someone on here told me that I needed to start shortening the light to trick the plant into flowering. I did that and it worked almost immediately. I got two small jalapeños, then couldn't get it to grow again. At some point one of the bulbs in the Aerogarden quit so the plant just maintained.
