Many growers strip that growth away, which costs labour and gives up part of the crop. Under-canopy bars put light where top lights cannot reach, adding roughly \u003cstrong\u003e35–50 cm of usable canopy depth\u003c\/strong\u003e (Faven's figure is 14–20 in) and evening out \u003cstrong\u003elight penetration\u003c\/strong\u003e from the top of the plant to the bottom.
