Poor Man's Cannabis Grow with CFL's Surprise Sprout - Day 20 Topping my plant

This takes a really long time I KNOW!!! But, to be fair this plant was like super elastic like a bean sprout or a blade of grass. Whatever, at least the root seems to be strong. I don't have the space available to grow giant plants. Thus I will top my plants in an attempt to control its height. I'm also keep these plants in a small 1 gallon pot to stunt their growth as well. If you have other suggestion let me know.
