I'm having thoughts on air humidity levels in my greenhouse. I have always considered the levels to be good for growing when they are high. But I have recently begun to have doubts that they are too high. The humidity is seldom below 90% (both day and night). I think plants would benefit from having faster dry-up rate with a lower humidity. I'm planning on installing a dehumidifier to achive a daytime drop in humidity to ~70-75% What is your thoughts on this? What humidity levels (day and night) do you have?
