This experiment could easily fail, but I’m going to give it a try. I’m wondering if the arugula will grow quicker if I cut the rockwool in half. My theory is that the roots will reach the Tower Garden water sooner. This experiment is similar to cutting slits in the bottom of the rockwool.
If you’ve given this a try, then let me know in the comments.

 June 12: The roots are coming out of the rockwool so I placed the arugula into the Tower Garden. |

 July 5, 2015. One stock of arugula is doing well. The others probably didn’t get enough light. |

| We’re at 6 weeks now and this arugula isn’t as large as arugula in a full rockwool. I’m going to label this as a failure and move on. |
