Haha you have just discovered Stunted.
Stunted used to post here on AFN and when he stopped posting here he started posting at AFP.
If you google "Stunted Art autoflower portal" you will see much more of his work!
Easier still - Link Here -
Stunted Art
I used to chat with him about different grow techniques and other stuff but I haven't seen him around since last summer!
He lives in Australia and is Australian.
He grows in in all sorts of tiny pots, nursing them through each day drop by drop.
He doesn't just grow small he also grows od shaped plants, sometimes looking like candelabras and he even grew a plant with a knot in the stem.
The plant with a knot in the stem almost died as it was straggling itself!
AFN has in the past had Shot glass challenges but these are really difficult to pull off!

For me a Solo Cup in a nice size for a challenge, that will give a decent amount of bud to have a smoke!
