looking good.autos are known for being a bit pernickity delicate as a rule,but at the same time we can be a bit brutal with them.looks as though there more room if you lay the pot on its side.you gonna have to get brutal with this one,either that or chop the top half off and we dont want to do that.
bend bend a lil more,come back in half an hour and bend it some more.i dont do it at all myself (lazy) garden wire its a thick green stuff,pipe cleaners,velcro strips or good old fashioned twine can be used.even cable ties at a push,if it snaps tape it up.
a lot of great lil grows in here
