Canna: They are not on a table... I run two tents so I can grow perpetually. There are multiple strains going. I have trays underneath my pots that catch the runoff so it doesn't go everywhere lol, so I need to shop vac up the water. Yes if they were on a table I am sure it would be much easier like you said. Maybe I will be able to think of something that will elevate the pots a few inches so they are not sitting in the runoff, while letting it pass through to the tray underneath. Thanks everyone
