Sometimes Bob is stupid. I just received an email from Greenhousemegastore.com (Danville, Illinois) asking me to write a review of the 1020 cell inserts that I recently purchased from them. Duh.I usually buy trays and inserts from Growerssupply.com, in Iowa: http://www.growerssupply.com/farm/supplies/cat1a;gs_pots_trays_containers.html The cost per tray is higher, but the shipping seems to be lower.

So, I guess I didn't buy them from growerssupply.com this year.

They offer 10 different insert configurations, any of them for $8 per set of 10.
