Shake, Don't bother with the LEDs they just aren't there yet. You really don't have enough light to get them much pass breaking the soil. You can get some CLF's pretty cheap these days, Ralph's has them buy one get one free and I believe they are about $1 a piece they have both 6500K 23 watts and 2700K Walmart also has them for a little more. If you are only going to use a single spectrum the 6500K will do better then the 2700k. I'd say you could probably get a decent little micro grow for around $100-$200 not including cost of seeds but with only what you have got already going I don't think you'll be getting much in the way of results.
