Left town for four days added 5 gallons to the rez and got the ppm up to 915. They drank it all so 25 gallons for the week... thirsty chick's. Doing a rez change tomorrow and moving them to the room I built with 9' ceilings and a 1000w hps I'll put the led's out there for supplemental light as well. So the next 3-4 weeks I should see some great gains.
