Yep the tubs are going to be filled with dirt as im not a fan of Paper ect as a substrate.. The tubs are being made out of 13mm Natural Polypropylene & i will be adding supports to the outside & inside of the tubs so there wont be any sagging.. i am planning to use very heavy duty draw runners so the tubs can slide in & out with ease.. although it doesnt show any of this on the pictures, basic design software sucks!.. the build should be starting in around 2weeks whilst i get some supplys together i will keep you updated![]()
