Interesting. Note that the plants are nicely maturing. At a one hour rotation it should be enough for the base of the vases to pass through the water every hour. The one hour duration is also fast enough to prevent gravity from directing plant movement.
Assuming it can then stand up to normal operating conditions it may well turn out to be useful on earth. I am much more skeptical regarding space conditions. We are then dealing with zero gravity and this provides little in the way of acceleration in any direction.
Who knows on this unusual product at this time but it is worth watching..
