Sour diesel auto

So it begins, have you grown that strain before Invi? Is this an outside grow because I see the rocks on the soil and wondering if it's to protect from wind and critters digging them up? How long does the breeder say it takes to finish.

Inside in a 4x4 tent. The volcanic rock is keep the coco from drying too fast and dust. Also to soak them up with insecticide and neem haha 
the seeds are from ILGM grow time is 10-14 weeks from seed. I also mixed the smaller more porous pieces if volcanic rock in the coco mix, read it was really good. And no havent grown this one and fairly new to every strain tbh haha

Very cool thanks for the explanation.
