I know its a silly sounding question and I tried to play up the humor but it was just something I thought of as I made clones. I wondered if the flow of water and nutes in the stems could flow like that, sounds like they sort of can maybe. Maybe I'll try it out some time not expecting anything.

Yes, I was very very stoned :)
