Ann: Roto-Gro Launches Growing Management Services, page-6

I don't see companies signing contracts for large orders unless they have a chance to see the units in action for themselves. Maybe RGI have supplied a certain number of test units that are currently on trials? Each MM company may have requested 3 odd months to see how they go.
This would give them first hand proof at the speed of the plant growth and their production capabilities.
And now, maybe they are just running the numbers, looking for new large warehouses/facilities, signing new lease agreements and will be placing orders soon.
Or something like this hopefully
