Thanks MRDiff.

Some of the plants, particularly the BA were showing signs of heat stress. The edges of the leaves were starting to curl up. I raised the light from 14 inches to 18 inches to see if that helps. If it doesn't, I guess I'll take it even higher. Canopy temp (while the light is on) is running 80 to 83 degrees with the ambient room (house) temp running 77 to 80. With the light off, the canopy temp runs 74 to 77. The house A/C is always set at 78.

The canopy temp is cooler running the HID than running the CFL's. With the CFL's the temp would climb to 85 and sometimes 86.

Humidity is about 36% with the light on and about 40% when it is off. This is with the humidifier set on high and running 24/7. The exhaust fan also runs 24/7.

The light is currently on a 18/6 schedule. Last time we ended up running the lights 24 hours during vegging. We're thinking about keeping it at 18/6 with dark time during the day (noon to 6PM) to help offset electricity costs. Our electricity is cheaper betwen 9PM and 9AM.

The 10 buckets are taking about 3/4 of a gallon of water/nutes each day. Still running 1/2 strength nutes and the plants seem very happy with that.
