Rdwc sog

Hi there! New grower, currently trying to plan my set up for future grows. I was thinking about a RDWC SOG, using 2 liter bottles, 4 per square foot. I was thinking I could have 36 or so bottles hooked up inline with a hose at the water level top point of each bottle connecting to the next bottle. Then a water pump in a separate reservoir of 10 or so gallons. Then the overflow hose on the last bottle dumps back in to the reservoir. I would probably only circulate once a day just to keep ph and nutrients stable. I would supervise the circulation each day in case of backups or overflows. Any thoughts on this type of setup?
