Finishing up my first indoor grow.  Using a Gorilla Grow 2×4 with an AC Infinity 6″ exhaust fan, along with two of their oscillating fans.  I’m using the HLG Diablo 350 and Coast of Maine Stonington Soil.  Gaia Green base amendments and bloom.  Also adding in Yucca from Raw and silicone.  I also add in worm castings from my worm bin, nice and fresh like Scotty says.  I appreciate all the help from the DGC.  You have been an excellent resource (and comic relief).  Be well!!!
