I have always vegged my grows until this one here so I can't guess about indica seed under 12/12 right off. I wouldn't try it myself. But I have no reason to believe it could not work out reasonably well.

yield : space : time : cost

I will be comparing this grow's metrics compared with previous successful grows. My feeling, looking at the colas and the calendar is that this grow will be above average cost/time/yield.
