Max Auto Barn

So I'm day 10 of breaking soil so decided to start week 2 of my Diary. That LED says 600W but I'd guess its not that great? What's the ideal height for this kinda light. To much different info online. GC did stretch but I think iv fixed her. I just feel like they are both a bit slow developing.... Day 11, after yesterdays concerns I Started using an app and have switched the flower switch on that unit as apparently its pretty wack and the red light will actually help the little autos along and without it on the apps suggest the light is wacker than wack. So I now Seem to have Par and intensity and DLI etc and all that stuff down now which I hope helps alot. Hopefully this will give them the light they was wanting cus my measurements by guess work were cleary causing some undesirable performance and issues. GC seems happier😏.
