Wow, i just relied to this, my RIU is acting up or its my laptop, i like the idea man, sounds like a plan to me, im thinking of moving up from the party cup lol
i have to water at alot now, i was think of cutting out the bottom, then plating it like half way in another cup with dirt, kina like pot stacking when people grow, instead of transplanting. maybe it use like 3 cups, just to give the roots some room
