Running a sterile vs Bennie reservoir: DWC

So I recently switched my vegging plants (3 of em, 10 weeks old) from hydroguard/live res to UC roots (basically pool chlorine) and sterilized water. Before switching, half my house stank like dank and near the tent it was especially strong. Now, with the sterile root zone, there is ZERO smell. Nothing. Totally odd. Anyone have any similar experiences? If the disappearance of the smell is actually related to the loss of microbes at the root zone then I think we may have to change how we think about live vs sterile res, at least during the couple weeks leading to harvest.

Peace

sounds interesting. what nutrients are you using? im new to this so im trying to figure out whatg to use.im running rdwc for 2 plants with(not autos) I have green emerald micro grow bloom and general hydroponics grow micro bloom. im not exactly sure how this is suppose to work. what all do i add , other than the 3 part nutrients, ive been reading and it sounds like i need to add hydroguard or uc roots , do i add this every time i top off res? do i top off res with just plain water or nutrient/ucroot and/or hydroguard mix? and also i read im supposed to use calmag also? same with this one do i add every time? i got a good quality ph pen and tds/ec meter im just a little confused to how this all comes together.

Thanks for anyones help
