T-Frames – Placement in 4′-Wide Boxes

Q.  Where do I place my T-Frames in my containers that are 4′ wide? 
 
A.  If putting T’s in a 4′-wide box you place them inside the box but at the outside edges.  That way there is 16″ between the T’s in the middle of the box, and with a 3 1/2′ aisle (which is the minimum you need in this case) you end up with 14″ between the T’s in the middle of the aisle.  Always place 4 T-s in a 30′-long bed or box – 10′ apart.
 
If you build the PVC arches and cover with plastic to extend your season, the plastic doesn’t come straight down, but would be angled back in toward the box at the bottom, so a person can walk down the aisles.
