Arugula in the Tower Garden – Burpee Seeds, Sliced rockwool, eight holes

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.

July 20, 2015

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.

Cress in the Tower Garden

I picked up some Burpee Cress (Berro Cresso) to try.  The packet says days to harvest is between 15-35 days.  I used this seed starting procedure, but poked extra holes in the rockwool like I’ve done with the arugula.  The seeds germinated in about 24 hours and are looking healthy.

The seeds were planted July 22, 2015.

I’m going to close off this experiment and call it a success.

Circle Cut Out of Rockwool to Give Room for Seeds – Arugula in the Tower Garden

I cut a circular slit in the rockwool to plant the arugula seeds.  (My wife says all I need is a little smile on the plate now.)

Cutting a circle out of the rockwool didn’t work as well as just cutting a hole in the middle and planting the arugula. So I’m going to mark this as ‘failure’ since it might be better to just cut out a hole.

8 Holes in Rockwool with Multiple Seed Per Hole – Arugula in Tower Garden

With the success of putting 8 holes in the rockwool from this experiment, I decided to max out the holes with seeds and see what happens.  I poked 8 holes in 5 rockwool cubes and planted the following:

Rockwool #1 – 2 seeds per hole
Rockwool #2 – 3 seeds per hole
Rockwool #3 – 4 seeds per hole
Rockwool #4 – 5 seeds per hole
Rockwool #5 – 6 seeds per hole

If needed, I’ll thin the arugula seedlings to eliminate 1 seedling per hole.  Example: Rockwool # 5 will end up with 5 seedlings per hole.
