This is my second grow. Put down two cheese twin clones and added a rack of LEDs. Using gnat gaurd for this round and started in full size 15 gal bags so I won't need to transplant. I'm thinking about trying to SCRoG or SoG. But I'm hesitant. I also added a mushroom grow kit to raise the CO2 level in the tent. Any tips for a beginner? The photos show the comparison over 8 days.
