At latitudes where summer days run twenty hours, photoperiod indica plants refuse to flower until September and then get caught by frost, which is why autoflowering indica seeds dominate up there. The long days actually suit autos, since more light hours mean bigger plants in their fixed ten week window. Grow reports from Scandinavia, Alaska and northern Canada, with planting dates and which auto lines finished before the cold, are collected on https://kushindicaseeds.com (https://kushindicaseeds.com) in a northern thread. Two staggered plantings in May and June usually beat one big one.
