I don't normally write reviews but I had to share this! You can buy a pack of Midwest's Medium (30-32Q) Liners and two of these liners fit perfectly inside this tub! Now you can literally do two grows side by side in one bin! Even better you can purchase 3 of these tubs and 2 of the 3-pack medium liners and you have enough for 6 grows in 3 tubs! I am super happy I found this!
