It feels like my 5 gallon reservoir for my 4 wicking buckets take a couple of weeks to go down and sometimes I refill it with plan water..Thanks! How often do you feed them? Every time you top up, or every couple of weeks?
I bought the Scotts Earth Grow Brown Mulch from Home Depot. At first, I kept passing it by because it had different color pigments, but when I read the label, it said it was safe to use, so I bought it. I topped some of my pots and grow bags with it and found that it does a good job keeping the soil moist on top and my reservoir take longer to go down.
