I like Amanda's potted Idea. I have seen conversations on here on the Iris thread about places you can buy discount pots, though it has been quite a while. And then tell hubby you need a house with a patio that will hold 100 plants. I saw leave them on the patio and set up a drip system on a timer for each plant, because if they are on the patio and out of the heat then they should not need to be watered very often. Just ideas. I guess it really depends too on how long you are going to be gone at a time, whether you are traveling during months where the plants have already gone into dormancy, etc;
