This is a quick and dirty tank.
I am building a DIY greenhouse and needed a lot of tanks CHEAP.
It is made out of 3/4″ plywood and 1/8″ plastic used for shower stalls.
You can build it to whatever size you need.
Easy to cut holes wherever you need them.
The best part is that nothing has to be perfect.
The outer plywood box is just for structural strength!
The inner plastic box needs to be cut close but any oops can and will be covered with caulking.
The tank above is 4′ x 2′ x 1′.
Total cost of the tank above was less than $30.00
Sheet of 4′ x 8′ plywood $23.51
Sheet of 4′ x 8′ plastic
