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.)

Circle cut out of rockwool to give room for more arugula seeds.

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.

August 12, 2015 – Harvest.  The arugula with 4 and 5 seeds per hole did the best.

Slitting the Bottom of the Rockwool for Arugula in the Tower Garden

This experiment is similar to cutting the rockwool in half. I’ve cut slits in the bottom of the rockwool to help the arugula roots reach the Tower Garden water sooner.  The seeds have been started using this seed starting procedure.

After 6 weeks the arugula in the sliced rockwool grew well.  I may try this again.

Cutting Rockwool in Half for Arugula in the Tower Garden

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.

 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.

What’s the best planting arrangement for Arugula in the Tower Garden?

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.

Harvested July 3, 2015 – I weighed each
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.
