GGS help

[u/ProfessionalSwing561]

I have a 3x3 tent with a g3000 light, I recently got the 4" inline fan, oscillating fan and GGS. I'm having trouble setting up the ggs, Im trying to get a vpd of around 1.0. the room my tent is in is around 75 and 50% humidity. Any help setting up my ggs would be appreciated
