I’m currently in flowering, and I always have to deal with higher-than-I-like humidity, but my VPD is nice. For example, looking at my logs from yesterday, my average temp was 79 and my average RH was 69, with an average VPD of 1.1, which I’m pleased with.
I have wrestled with the humidity, and I just have to deal with it. I tried a dehumidifier but that creates enough heat to bring my temps up past where I like. Just rolling with it.
Anyways, I guess my question is which is preferred – shooting for a good VPD even if that means going higher/lower on temp/RH or trying to maintain proper temp/RH even if that means the VPD will be higher/lower than what’s needed at that growth stage? In other words, we see charts that show optimal temp and RH at different stages of growth, but is it better to stick with proper VPD?
My plants are not complaining and seem to like the environment, so that also tells me a lot as well.
