The Duck Tape did the job, pitch black in the shed. I have not got the timer working correctly yet. Girls look fantastic. New growth is getting bigger, maybe because it is growing. Colour still really good, no yellowing. This coming week I add Big Bud to the Bloom A and B plus the Voodoo equivalent. Not dry enough to feed again as of yet. The moisture meter is a good tool. Over watering is a cause of many troubles.
