The bubble lamps are as described earlier. Two 5 gallon buckets flipped upside down for vegging a single plant in my bubble bucket. One uses white paint and the other uses hardware store reflective insulation - way better than mylar. I designed two as a comparison. They are pretty close in output. The painted one runs cooler because of airflow out the venting holes.

The updated plant pic may look the same as the original from a few days ago as it is just under 1" taller but is almost 4" wider! Currently it is 4.7" tall and over 10" wide. Never seen one stay that low before. Hope it stays that way.
