Light too close for seedlings?

[Sixpackdad]

What did you get for a humidity controller? I was looking at a few last night thinking about all that vapor pressure deficit stuff.

Lowering temp and raising RH ,during lights out?

im reading an implied question with two parts. 1. does humidity and temperature factor into flowering 2. if they do then how do i use it to my advantage? i think mainly you want to apply the concept of Vapor Deficit Pressure. [image] [image] [image] [Humidity 102: Vapor Pressure Deficit — VPD Chart]
