Tomato Boxes 2010

I built these boxes for tomatoes this winter so I could keep the different heirloom ones seperated.They are 3/4” pressboard with 1 coat of primer and 3 coats of outdoor paint inside and out on each one.I drilled drain holes in them and put 2”x2”frames in them and runners on the bottoms. I then lined them with black plastic bags.They are different sizes because I used scrap wood from a housing project near here.I sure hope they work for me.
Sizes are
2 boxes at 33 1/2” L x 14 1/2” W x 16 1/2” deep
1 box at 20” L x 12” W x 11” deep
1 box at 27 1/2” L x 14” W x 18” deep
