They're still growing, and all similar in size. Makes me wonder if there is any difference between red and blue, and if the white encompasses all of what's needed to suppliment every day lighting. More controlled experiments should yield more conclusive results, but I'm ok with what I've got so far, esp. since they're using approximately 3 watts of energy, vs probably 13W using a small CFL for the same area.

We're trying an upside down tomato planter that cost $0 out of pocket, as I had all the materials here. The plastic coffee can was originally planted upside down (as seen in this post), and once the material settled and enough was added to bring it close to the top, was seeded and sprouted with no problems so far. Now hanging upside down, it hasn't whithered, and is fighting gravity.

This is the start of a "Japanese Tomato Ring" which has been documented in a number of places. Mine (have 2 so far, going for 3 or more) are smaller than the ones written about (instructions on the internet are for four ft diameter and three ft diameter, mine are 29" and 22", while the third will be only 12"). Other differences are the materials used are composted horse manure and wood shavings (animal bedding) instead of leaves. The rest will be the same.
