My ladies are growing great now staying in the 60 - 70 percent humidity range now during most of the daylight hours. Which keeps the vapor pressure deficit around 1.34 to 1.65 which is a little high, but much improved over the higher than 2.50 I was getting. I am having trouble with the tent having higher than 95% humidity in the mornings which puts my VPD very high.
I think I'll invest in a second timer to have the humidifier on a different on/off cycle than the LED lights. I currently have both my lights and humidifier on the same on/off cycle. If I got the second timer I could have the humidifier kick on after the tent heats up a bit and the humidity from overnight in the tent drops a little.
I love my LED lights the plants look great and are growing great guns, they heat up less than other lighting solutions, but still I have a temperature range between 70 and 85 degrees. According to the Marijuana Horticulture book (by Jorge Cervantes who used to write for High Times) this is a good range for my girls.
I also trimmed away some none productive leaves and branches at the bottom, not quite lollypoping them but close. I won't really lollypop them until they have a couple weeks of flower time so I can really see what leaves are just sucking up energy from the plants.
No pics of post trimming, will post next week
