I am fortunate to have the room to do so many. I can get about 19 six inch pots of 3 to 5 bulbs each in a refrigerator dedicated to winter forcing. Plus I have a covered stairwell from outside to a basement door. I put pots of bulbs in those big totes and then cover the totes w/ blankets and rugs. I could probably max out that space with 25 more six inch pots. However, I usually make a couple big pots of forcers and put maybe just one or two big pots in a tote or two.
