I too have seen the hipe on the flow hive. As pictured, I don't see how that much honey can be taken from such a small hive without starving the bees. I am guessing they must feed them a lot of sugar water, which, in my opinion is not what the bees need to stay healthy. It's too new not covered her book, but Jacgueline talks a lot about natural bee keeping.
