Sometimes experiments happen on accident. I ordered rockwool from Amazon, but didn’t check the size. When it came, it was about 1/4 the size of the rockwool recommended in the Tower Garden.
I cut them into double-rectangles and planted the same seeds on each side. My plan is to place the rectangles into the Tower Garden in 2 weeks.

Placed plants in Tower Garden. So far they look healthy.
The plants were growing great until aphids attacked and I had to start over. I think the smaller rockwool will work fine, but I’ll make sure to purchase the larger next time since there’s no advantage in purchasing the smaller size.

Quick update. I harvested a gourmet lettuce mix and discovered that I’d used 2, 1/4 size rockwool and the lettuce grew fine.
