Yes, water and nutes are absorbed thru the leaves.

I live in the desert. During the summer the temps get to the 120's, and humidity get's up into the teens . You mentioned nothing about the heat, but excessive heat combined with low humidity, and the plant can struggle to keep upper zones hydrated.

I veg indoors, and mist the plants once daily, as they much prefer the higher humidity. But I flower in an outdoor shed, where the A/C keeps the temps around 90ish and the plants have little to no problems adjusting. Keep an eye on them daily, especially when they start filling-out. The larger the plant, the more moisture they lose thru the leaves. (transpiration)
Oversize pots will hold moisture a bit longer, but don't keep the soil wet all the time, will cause root-rot.
It can be a fine balance between "ok...I need to water later today" and "shit...I should have watered yesterday."
Rusty Trichome Reviewed by Rusty Trichome on . will LOW humidity hurt a plant? If your humidity is around 20% or lower can it be bad for the plant? If it is I don't understand why it would be bad for the plant because the leaves don't absorb water do they? Rating: 5
