Heck, I change my res every week, unless they're little and the water is cold.Outside soil to inside soil to hydro is the natural progression. My first hydro was ebb and flow. I got a cheap setup since I was not sure if I would like it. Bulk head leaks and failing pumps guarantied I would hate it. Had to spend more money.
Tried cocoa coir drain to waste. Healthy plants in almost half the time of soil. vary little equipment. but you have to keep up on the watering regiment, every 2 days+/-. Had to spend more time.
Switched everything to DWC 4 years ago . DIY you just need tote (2-3 gal per foot of plant height), net pot, nutes, air pump, air stone, hydro tone, PPM, Ph meters. Separate res per plant makes it easier to monitor and quarantine each plant. Only maintenance is change the nute/water once a month. Grows faster and healthier than the drain to waste. Cheap setup and I can leave town for two weeks without worrying bought it.
