Coco wast water question

So im using 6 3 gal buckets each with its own waste water saucer underneath. I was wondering is it ok to leave the waste water to evaporate in the saucers or should I just discard it? or just leave it for the coco's to suck up later.
thanks

my advice: Discard. If you leave it to evaporate, it could grow bugs and general scum. You don't want it reabsorbed ... feeding 'til runoff and getting rid of the runoff is your #1 protection against nute buildup and lockout. Especially since coco slowly bleeds sodium. cn

Awesome thanks for the feedback. Im going to start getting rid of my waste water for now on by using a shopvac or something like that

That works pretty well. Be careful not to give your honeys an unscheduled grooming, though. cn

yeah that wouldn't be to nice for them

You need to have a way that salts and stuff can leave the system. Ideally with coco 10-20% of what you put in should come out. 10% if you mix nutrients light, 20% if you mix stronger. If you are lazy you can use a rubbermaid tub with something to hold your pots 6" above bottom. That way you can accumulate water for a few days then dump all at once.
