In order to get more space for growing arugula in the Tower Garden, I decided to purchase full block of rockwool and cut my own. I found some at htgsupply.com. (I also purchased from them a single-bulb, t5 fixture to replace one of my fixtures that went out.)

Thanks to Joe of Level2 Concepts for the straw idea.

After 2 months and 2 weeks, I harvested 11.2 ounces of arugula. This was in the Tower Garden a lot longer than I would like. The arugula gets very strong with age. So if you like it spicy, let it grow. 🙂
I’m going to experiment more with cutting my own rockwool, but on a shorter time-frame to better compare.
