Attached are photos of the 2x4x6 cabinet, which is lined with IR Blocker reflective film. Net pots are hung on wooden top to a rubbermade container, which sits inside insulating sheeting. Nutrient solution is 2" below bottom of net pots with fog (ultrasonic) in between top and surface of solution, which is aerated with 2 6' flexible air stones and aggitated with recirculating pump, which also feeds 15min each 3 hours. Solution is 5.8 to 6.1ph and around 600ppm, since flushing a few days ago and is changed each week. Fert. is GH NovaBloom, two part. Solution temp is around mid-70's, so it is circulated thru fridge, bringing temp down to mid 60's.

Exhaust fan is on 15min/hour and also thermostatically controlled to vent at 90 degrees. CO2 augmentation is coordinated with regular venting and lights on schedule and keeps concentrations at 800 to 1200ppm CO2.

Plants seem better since purging and have restarted rapid growth. Light is being reduced 1/2 hour per day and we are 11 days from 12/12.

Thanks for all the help and comments!!!
