I’m narrowing down the best way to grow arugula – at least for my Tower Garden setup. Of course, your mileage may vary. 🙂
Burpee arugula seeds seemed to produce a higher yield than Ferry Morse, Slicing the bottom of the rockwool seemed to help as well. Letting 8 plants grow in one rockwool also produced a higher yield.

I sliced the bottom of the rockwool, poked 8 holes around the center hole and put 5 or 6 seeds in each hole. Two rockwool cubes are the normal size. Two are the quarter size doubled left over from this experiment.

| The arugula planted in the full rockwool cube is larger than the 1/4 size doubled. | |
