Well, we've been back from the Cultivate '16 trade show for two weeks now, and have almost recovered! We met way too many customers and potential customers at this year's show to possibly count. Thank you to all who stopped by our booth!
One question of sorts that seemed to come up frequently revolved around the type and size of plants that can be grown on Ebb and Flow benches. Many people were under the impression that you can only grow small plants like 4" pots of geraniums on Ebb and Flow benches. While Ebb and Flow benches are a fantastic choice for growing crops such as 4" pots of annuals, etc., they are certainly not limited to such crops. In fact many growers grow all different sizes of plants on our benches. It is not uncommon to see 6", 8", 10" pots, and larger nursery pots up 5+ gallons in size being successfully grown on Ebb and Flow benches.
The key to success in growing any size containerized plants on Ebb and Flow benches is using the proper root media (soil mix). With any sub-irrigation system, it is important to have a significant portion of the media consisting of an ingredient that readily absorbs and moves water through capillary action. This is typically medium grade sphagnum peat moss, coir (coconut hull waste), or a similar component. One or more of these ingredients should make up 40% to 60% of the total media recipe. Fortunately, these types of growing media have been shown to be ideal for growing virtually all types of plants (with a few exceptions, such as orchids, cacti, etc.) Virtually all of the readily available commercial growing mixes are already designed to work well with a sub-irrigation system.
