I actually use 2 cups too but my lower cup is clear and the roots don't come out like yours they swirl around on the bottom of the cup with the plant, I like Mc's bottom feed idea but are you soaking it till it reaches the top or just wetting the bottom? would make sense the plant is growing faster if its actually reaching down for the water so im curious as to how much you let it get wet before you pull it out as far as feeding from the bottom goes Mc

As simple as it sounds chron, like everything else I have to pay attention......this is just my experience...but if the pots or cups or whatever get too dry, the water won't wick up correctly. Your attentive skills have not failed you, so, if the container feels too dry, which is more of an intuitive skill to asses, I use my turkey baster to water from the top a little....once the capillary action is jump started, the whole pot will absorb the water. You can leave them in for as long as you like...within reason, or until the top of the soil gets the water. I'm getting good results this way, but I put 5 in grobags yesterday and they will be top watered for obvious reasons.
