Indica strains are more suitable for the SOG technique than sativas. Indicas are shorter, bushier, and more consistent in size and shape. They flower faster and produce denser buds that form a tight canopy under the light. Sativas are taller, lankier, and more diverse in size and shape. They flower slower and produce looser buds that create gaps in the canopy. These traits lower the light efficiency and yield of the SOG method. Some growers may choose to use sativa strains for their distinct effects and flavors. They can still succeed with the SOG technique with some adjustments.
