I grew my sweet peas in empty toilet roll tubes for the first time this year & I wondered the same myself, but once stood on it's end watering is easy and no compost escapes from the bottom. I presume that when ready for planting there will be enough roots to hold the compost together and avoid the whole thing dropping out of the end. I am going to do sow my beans the same way this weekend.
