Reach out to Randy he said he wanted to send u a new device they were working on that hooks to your power source and has sensors in the room for temp and humidity and can dim cia Bluetooth. He is gonna send ripper two I think. I know he mentioned getting one to u man. I want a dimmer too but hanging it at the ceiling has worked from seedlingI am still trying to get my hands on a dimmer but I can tell already that the light from the 320w vs the 240w is brighter and since I am growing 6 plants with the 320w and only 3 plants with the 240w its going to be nice to see who its all works out
