Starting to bend over at 24 days from seed. Plant looked happy and supple and appears to be growing fast. Brick and bent coat hanger worked well as training tools. At 25 days, discovered that I had mixed up which side of my timing power switch was a timer and which was always on. For the last 7 days, bubbles and temperature control were switched off for 4 hours per day. Oops. Appears to have been okay but was getting too much light and not enough bubbles for that week. Plants looks good though so I hope this doesn't matter too much. Only 7 days of 4 hours each day of mess up.
