This is awesome. I wanna try a one bucket setup, just want to ask some questions, how important are the water temps? I don't intend to keep mine inside as it is spring here so outside would be the right place. I read the first page about the nutes you use and how often you change, just want to confirm the top ups. Is that with regular ph adjusted water or is that a nute and ph adjusted mix that you top up with. If I read correctly its a 45 day cycle between depleted nutes and changes?
A single bucket would be a great learning instrument!
The water temperature is critical in my humble opinion. 62-68 degrees is optimal. You will begin seeing pathogens starting to thrive in 73+ degrees.
45 days is about 31 days too long to let your reservoir go.
There is two schools of thought generally speaking when it comes to topping off the reservoir.
1. Top off reservoir with ph adjusted water only to maintain proper reservoir depth.
2. track your nutrient usage and add ph adjusted water and nutrients to obtain your desired ppms.
I use method number two.
If there is interest in some calculations for method two, I would gladly explain it.
