Can you add more space, like an extra row to the top or longer rows?

Yes, we can add more space...

Yes, we can add more space. We only recommend adding an extra row to the top if you're growing small, short crops like lettuce. We can install longer rows up to 35 ft long, if you don't opt for a vestibule. This would also require decreasing your lighting to avoid overloading your farm's electrical system. It can also be refitted for plant propagation without having to change the power load.  This would depend on the configuration of the farm. We believe we’ve covered the majority of feasible options that would be suitable for your needs, but feel free to ask. We’re always open to considering other possibilities and will be sure to give you our honest opinion on the advantages, disadvantages and feasibility of any proposed designs.
