Is there a source on the internet one could purchase bulb crates and 3 to 4 inch pots?
I buy mine locally. I was told that in every region of the country there is at least one large wholesale business that direct imports bulbs from Holland. These are the crates used to ship bulbs. They always have them for sale. I've seen them listed in the Brent and Becky's Bulbs catalog or maybe on their website. With local pickup I can get them for $3.50 a piece. I think everywhere I've seen them on the web they were about double that price.
