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.
