You dump it out, mix in some more EWC and 1st run ammendment, remix, water, & re-cook.Dam brother those look amazing and nice lights to congrats. I cant wait for my QB lights to show up it will be my first attempt to deal with electrical issues lol. Idk but from the videos I seen on you tube how to set them up doesnt seem to difficult lol. But yea those buds look great man congrats. Also when u harvest and go to re cook ur soil do u jus leave it in those big pots an put the amendments back in threw the top? or do u redump it out and mix it up again?
