I Just threw one in there to see how she does, i read alot of journals , off this site, of people growing with them, i will update you guys on the progression of it for sure, my theroy is that if i Lightly water the plant, and keep the TOP of the hagers dirt moist, the root will go toward to top.
ALSO there are new ones out that uses circle sponges that hold dirt/water from gravity, so i think IF this doesnt work, then i am going to try that out, thinking that will solve any issues that you disscribe but idk if that was just your experiance,
I did find the study you were talking about withthe wheel,
How Do Plants Know Which Way Is Up And Which Way Is Down? : Krulwich Wonders... : NPR
But, idk why they sell these things IF they didnt work, my dad has grown tomatoes in them and they were great, i will run it through and see what i get tho, like i said some people have done it so far so good, even if it root balls i should be able to get a oz or two from it if i can.
Bro, the more I think about it.....if you can lst the branches equally around as they come up..........oooooeeeeeyaaaaa! The only trouble with mine that led to low prduction ( tomatoes ) was the fact that it would dry so quickly......at the time I was NOT focused at all. I just bought a house and couldn't live there because I was carin for dad and I had to live there with him, so the thing was getting shitty care. I'm excited ta see what you can do with it! +reps for gettin the plant in it without killin it!
