So now each bucket has Fresh water and the air stones and everything in it. Then we add in all of our nutes. We started at a nute ratio of 6 to 12 I believe maybe even 5 to 10. Were now using a nute ratio of 9 to 18 though but that's cause they're a lot bigger. But so now all the buckets have water with nutes. Now is when we pH because adding nutes can change pH's sometimes and you don't want to have to pH twice. We keep our pH between 5.5 and 5.8 and try to keep our water temps around 68 degrees. It is good though to clean your buckets between harvests and between veg and flowering if you want to also.
