Mix Photo/Auto Grow

pH was low then high then low. PPM was over 3000 (meter only reads up to 3000). Only fed pH water this week and no nutrients. Much improved today, finally fed but will report with next week's data. Also rerouted the exhaust fan to outside instead through the room. But temps still high in early afternoon to early evening up to 90 and need the fan at 9 or 10. Since the first harvest I'm now saving money every month that would have been spent at the dispensary, soon to purchase a room AC that pumps directly into the tent.
