well, ive DEF thought about that and have been planning it and thinking about it for some time.
first of all, the container is pretty small as u can probably tell from my pics, therefor shell become root bound before long and as long as proper nutes, light, and co2 are adjusted its size will eventually be limited by the container just as a fish grows to accommodate his tank.
second, i will preform a combination of FIM, trimming, and topping to limit growth.
lastly, i will flower very early as early as 1.5 weeks and as late as 3 weeks, depends on its rate of growth
check out kindprincess's shotglass competition for more information and to see why this will work. also note that i am using a larger cup than her and therefore will have less of a likelyhood of producing all males and will hopefully yield more
