If you have something to smoke, that's great that you want to use just (or mostly) LED's. It will be very intersting to see the results. If you're short on weed though, I would just blast them with whatever light you can, especially when they start to flower.

In other words I don't want you to go without smoke just to appease my quest for knowledge.

Please keep us posted. Can't wait to see. I want LED's to work, dad gummit.
