$IDVV About the OGGL: The OGGL is the first purpose-built, self-contained, off-grid growing laboratory. Built in a low-cost shipping container, the OGGL has integrated solar modules and lithium-phosphate batteries coupled with a generator backup to supply uninterrupted power to the grow room. The OGGL is configurable for the three stages of the growing process, which are: vegetative, flowering, and cloning.
