Im going to germinate with rockwool, and transition the rockwool to clay pebbles buckets. My tray is 3x3 and I want to be growing 3 plants. Because I bought the fruity mix! Check out my pics and see if im missing anything please
In my opinion I seen in one of your photos you have fan inside of tent behind HPS light , I think you need to take the fan out of tent cause it will add heat in your grow tent , but I’ll put the fan outside the tent and run tubing from scrubber to one end of light than tubing to the other side of light threw the vent hole to inline fan outside the tent pulling stale air out of the tent and helping cool light off at the same time . The only moving device inside the tent will be a small oscalating fan that don’t cause added heat .
