you can get a ph and feed doser to help with the swings of them. but you have to set up a water line to the system to self fill res depending on how long your going to be gone. and how big your res is. but put a float valve in your res for a safety shutoff to the water.you can buy the float shut offs at most grow shops. good luck

The blue labs PH dosiers are over $400 these days. I am glad I bought mine for the RDWC and it was a stretch for me @ under $300. Its totally worth it but you have to have the $ first. I did finally have to replace my sensor but they are down to $45 now from $90 when I bought it.
It makes 0 sense to me why component prices will go down and assemblies would go up
