I’m trying to get as much arugula as I can out of one piece of rockwool in 35 days. (Ferry-Morse seeds say 35 days to harvest) So for this planting, I took 5 pieces of rockwool and planted each in 5 different ways using this seed starting procedure.

 4 holes poked around the center hole with 2 arugula seeds placed per hole – 6 in the middle |
 4 holes poked around the center hole. I put 2 arugula seeds in each hole. |
 8 holes poked around the center hole. I placed 1 arugula seed in each hole – 2 in the middle. |
 4 arugula seeds placed in the center hole. |

| 1 and 1/8 oz | 1 and 1/4 oz | 1 and 3/8 oz | 1 and 1/8 oz | 1 and 3/8 oz | |
| The winner here were the 2 that had 8 seeds planted. It didn’t matter if the seeds were spread out or put all in one hole. (Instead of 35 days, I harvested after 48 days.) |

| Since the rockwool with 8 holes did well, I decided to run this arugula experiment to expand on the 8 holes idea. | |||||
