Hello. I've got a few plants indoors doing well about a month into flowering (7 out of 9 plants were female. Cool, hey.) but I have to leave them unattended for up to a month. The lighting is fine, but I need some way to keep them watered. I was thinking of Putting the pots in big trays of water, would this work? Perhaps a drip system from bottles, but that'd be much harder to set up. Any suggestions?
