Glass vase from walmart works nicely

Im from the UK; is a pitty really, from reading peoples threads walmart and other american stores are very usefull for home DIY and growing. Will have a look around though. Cheers

you can buy a 6" cooltube for 40-50 quid in the uk, saves all the hassle. it will probably cost you 30 quid to make one, and the bought one wont look ruff! lol

Hi Rob; where have you seen a cooltube for 40-5 £; obviously a bought one would be ideal for me as i aint no handy man. Cheers all for help
