LED lighting

We use many forms of lighting when growing medical cannabis.  I investigated LED's because they use so little electricity.  LED lights work really well during the vegetative period.  Hanging a large CFL along side the panels aids as well, but it's not required.  If LED's are used during flower, the buds are typically not as large as with HPS lighting, or when grown outdoors.

Below are two examples of plants grown under (1) a UFO, and (2) under panels.  The first picture is of various newer clones; the second is of two Jack the Ripper plants.  We added a CFL in the middle of the panels for additional light.  It's hard to really see the plants under the UFO with the glare from the mylar as well as from the light itself.

Lighting isn't cheap, and sometimes patients live in older homes where they only have so much power.  LED's can be a reasonable option for them.  Smaller buds process into medicine just as well as big buds.  With LED's it's a win win - less heat, less electricity cost.  Plus they look awesome!
