deja,
I have to agree with Weedhound...I do about the same thing, except I change my containers each week, sometimes 2 weeks if I forget about them.. keeping some of the "old" water in the bottom of the container. This helps get/keep things going with the bacteria and essential goodies in each container. Much like changing your water in a fish tank, one never takes all the "old" water out when doing a water change/cleaning of the tank...this keeps things healthy the same way...

Peace,

Treetops Reviewed by Treetops on . DWC Maintenance? Just started doing DWC two days ago. I ran out of room in my Ebb and Flow setup and my plants became root bound and started dying, but they seem to be loving it now. I've got 9 plants sharing a 50 gallon res at 1100 PPM and 5.6-6.2 PPM. I've got three bubble curtains glued to the bottom. What kind of maintenance do you guys do as far as cleaning and changing the res and how often do you do it? Any help is appreciated!:jointsmile: Rating: 5
