Sorry for the late update as things have been crazy! My lighting is in flux, because one of my cobs on the Timber has quit working. So now, 3 plants are sharing 3 cobs with a 180 watt driver. I'm guessing they are now running higher wattage, as it has to go somewhere??? I've placed a clip fan to blow across the heat sinks and I've got the driver on full power! Hopefully, I'll be adding a 4 ft Flower Power T - 12 to the grow along, with a regular T-8/12 LED within the next few days, (along with replacing the burnt out cob).
