Closely!

I went to buy some Tomato plants plus a Bag.  No long Bags, OK purchase two short bags, somewhat astounded to see a message:-
"3X DEEPER FOR STRONGER ROOTS"  Immediate reaction:-
A Biden-like "Come ON MAN! Ordinary Bags are thicker than one inch" (Known by some as approximately 25mm)
THEN - I looked/read more closely - seems I'm expected to blance them upon their thin edge and slice along the other thin edge, I'm forced to wonder if they'll stand un-aided.
