Leftwood said:...with more moisture retentive mixes I would sometimes get seed germinating at the edges of the pot, rather than all over the surface. This I attribute to the faster drying of the medium at the periphery.
growitall said:Interesting... I often see that too with indoor growing and constant moisture. In my own case, I figure it's due to washing the seeds to the pot edges in the initial watering, as I often sprinkle the seeds directly on top of the soil mix, with no soil or only a little sprinkling of soil overtop.
