This is some text I cut from the serious seeds catalog regarding their Chronic strain:
"Our most commercial variety, this medium height, not too dense plant is the perfect combination of good yield and excellent quality. Smokers that know and grow choose this plant for its combination of appearance and sweet smell. With its indica background Chronic can produce up to 600 g/m2 without losing that connoisseur feeling. Grows a single huge central bud with few side branches. Do not top plants to encourage multiple big buds, as this strain does not respond well. Mild, sweet smell develops while flowering, take care to dry thoroughly after harvest (before packaging) to maintain this subtle fragrance."
Based on it being a medium height plant with a large single cola and few side branches, I would think it would be ideal for SOG.
Usually when doing SOG, people begin flowering at 8-12 inches tall from what I have read. Maybe somebody with personal experience can verify that, because I only know from reading.
