changing your reservoir
So the guy at the hydro store tells me to change my reservoir every two weeks... Well, I started doing that and have now resorted to topping it off every two weeks :) I mean FULL changes every two weeks for lettuce and peas??? I think the guy at the hydro store wants me to invest hundreds of dollars in nutrients for a dollar item at the grocery store. ON top of that, after topping off a few gallons here and there over the past few months my veggies are growing and producing perfectly fine. So I guess my question is how many of you guys change out your reservoirs in their entirety OFTEN? I mean I'm a hobbyist just having fun. Doesn't seem like I need to grow lettuce and peas that are going to be in contests? Any feelings on this?
