Sharing this in case anyone new needs help dialing in their environment.
My loft grow temps and humidity in the 2 x 4 has been all over the place with soaring temps.
Picked up a £15.99 humidifier from Amazon and dialed the room in using the vpd chart below that is specific for cannabis. Couldn't do anything about the temps but by walking up the humidity is sorted everything. I swear by this chart now.
Heres the humidifier, cheapest one I could find, large res and works a treat.
Good luck growers.
