Please don't laugh on my latest hack - because it works! Dehumidifier could only keep the tent at 60-65% when humid outside, until... I put in the feedback tube, taking intake through the top of the tent and feeding into the DH appliance. It dropped to 50-55%, but there was an additional benefit - 200W DH is keeping the tent warmer than when I had a 400W heating fan turned on (whose thermostat made the temp swinging every 5-10 minute by 2-3 degrees). So now, incredibly, the VPD has steadied around 1-1.5, which according to the papers represents weed nirvana.
This new set up kicked in Thursday evening - see the last part of the graph. The plants seem to be loving it. 5 days since watering, bags are light, leaves are still up - will water in the eve with 1/4 nutes. The only worry at this point is the smell - it is kicking in, wind is blowing around when it is sunny, and this may just be the biggest hurdle - soon I may need to bring this into a dark and cold basement garage. It may be too much of the shock.
