The Chemdog 91 looks like its still in veg almost a full month into flowering and then all of a sudden it sets up some pretty nice nugs. At least that's been my experience, that strain takes longer than everything else to get started but then surprisingly it doesn't take that much longer to finish. It's not really lanky at all once it does it, but because it waits so long to start producing calyxes i think it probably has a low calyx to leaf ratio. Not a production variety, but it's not a weak plant either like it's S1 the Tahoe. If only the Tahoe was as strong a vegger as it's mom or if Chemdog 91 had the calyx to leaf ratio like the Tahoe.
