Decent growth through the week, the runt is still with us but only to "see what happens". The 3 remaining trees have climbed to around 20cm tall and 30cm wide. Another week and I hope to be reporting on them turning tho I will still maintain the 4:20 lighting. A few issues in the week with rearranging the tent and trying to keep noise from the fan down but the trees didn't seem to mind.
