did you ever add any lights? Even if you have to add 24 watt cfls, from Lowes or Home Depot, they would surely help.
Man, what you are doing now and have going for you is great, but if you only get a few joints, you are going to be disappointed and NOW is the time to turn it up and get er done! Don't you want some coke can colas? then add some lights, cfls, up close to the tops and buds.
Peace
