i just installed my co2 system... i set it for 1500ppm works good so far.... but i have spider mites and i want to kill them... i was told to use co2 and rase the level to 10000ppm for one hour and it will kill them.. my unit only reads 6000ppm how can i tell when i get to 10000ppm and can this hurt the plants...:smokin3:
