This is my theory
When we plant out seedlings the bigger and deeper and more abundant the roots the better it is for getting the veg started in the open soil.They can be grown longer in the warmth and shelter of the house or conservatory
That said it must be the depth of the trainer that is the main benefit.
I will try toilet rolls on a few plants just to see what difference it makes
? Do they encourage more roots or is it just the depth
? Which plants NEED bigger roots to start off
