Thats a pretty good system for those mobile grows - but for those of us that use SCROG or a variation there of, it is not practical. And I'm not sure I'd want to be lugging buckets of dirt dripping muddy water through the house with the little woman present, she'd kick my ass for making a mess like that.If you are only growing a few plants then it is always a good idea to water the plant in the bath.If you have a shower even better has long has the ph is ok then you can just flush the plants straight from the shower head.Then wait for about harf hour by this time most of the excess water will have run off.If you can't get hold of a decent size tray then use a cat litter tray for one plant if you are flowering quite big if you are flowering small and the pots are not that big then you may get more than one in each tray.Then the next day you can take the tray and the plant to the toilet or bath and emty any excess water in the bottom or leave it if you want the humidity to become a little higher........tyke.................................
