I also saw these when I was trying to get a mental plan before I built my rack. But when I really got down to the details, I figured out that this would not work that well. It definitely COULD work but it's not what I was looking for. With this rack, unless you make some serious modifications, you would need to keep the lids on the tubs. There are lips on the underside of the shelves that don't let you slide tubs. You'd also need to put wood on three sides to keep in heat and darkness. Hope this helps in your decision!
