Riga Greenhouses Bases

  

Anchoring The Greenhouse

BASES

All greenhouses must be attached to a base or foundation. An optional galvanized steel base is available for all our greenhouse models. Another option is to use standard 6" x 6" landscape timbers as a foundation, which you may also want to anchor. Loose gravel, wood chips, brick or the bare ground are all nice flooring options for your greenhouse.
