I’m getting ready to switch to flower mode but am concerned that during lights out my plant will have light come in through the fan grill. I’ve read unless it is totally dark you run the risk of turning into a hermaphrodite.
Grobo has been tested and there is no herm from fan light exposure.
No issues with light seeping through. My grobo is next to lights that grow copepods which are running constantly… not much light comes through, and what does looks more like moonlight.
