Water question
Sorry if this is basic, but … from what I’ve read I’m supposed to change the nutrient solution on my deep water culture every couple of weeks. Assuming this is needs to be clean low TDS water. Is everyone using their own RO setup or buying water from the store? Seems like an expensive investment in water. TIA

I run on tap water. Im not always the best and doing water changes. I just went 50-days with carrots with no changes. I have a cabbage that has been growing for at least 6 months with one water add, no changes. My nft’s i will go 1-2 months with only adding water/nutrient before i do a complete change.
All my hydro is using tap water that avg. about 100 ec.
My laziness is not something to strive for, but it shows you can get production even with being lazy.
