Thanks for adding the Facebook comments mate
I do like the sound of the "Cola Wars" . Bit of recycling with the containers which is always cool for the environment
I think the Solo Cup Challenge could be first up buddy as its relatively easy to set up, members know the format and we always have a blast with those
A few have suggested beer cans or soda/pop cans. The only concern I have with this, could this play with ec/ppm as you would essentially be growing in aluminum?
Could growing in a metal container have any bad results etc?
