Here are the new pics. The first is my attempt to get them all in the picture at once.

below:a group photo of all of them up close

the next three are single plant shots. Their side branches are bushing out quite nicely now.
and finally, the roots. They are about a foot long on most of the plants.
I just changed the res. and filled it using bloom nutes this time. I want short bushy plants because this system cannot handle large plants. This system jkust seemed way cooler then the ebb and flows i was looking at. Plus, my four bulb t5 covers the width of the aroflo perfectly. Its a perfect match with light and system so its great. hope you all enjoy the pics.
