I leave most of my bulbs in their pots all summer, like Jim's greenhouses, they can reach well over 100F with the fans running. Recently I installed a shade fabric called Aluminet, and I love it. It doesn't cut down much on light, but reduces the temperature of the greenhouses by about 10F, and I now place sheets of in on top of the pots to shade them, in addition to it shading the greenhouse itself, on the assumption that it will keep the pots cooler. It is extremely light, and unlike black shade cloth it doesn't heat up itself. There's a posting about it plus pictures on my blog: http://www.thebulbmaven.typepad.com/ under 'Greenhouse Tips'. The bulbs that are being shipped have been harvested and are kept in trays in temperatures of about 65-75F. Fritillarias, Lachenalias, and other fragile bulbs are kept in dry vermiculite.
