Stacking FAQ
Expert answers to help you create a safe, professional vertical habitat.
01. How high can I stack them safely?
We recommend a maximum of 3 units high for the 4'x2'x2' enclosures to maintain absolute stability.
02. Do I need to drill holes to stack them?
No. The Spacers are precision-engineered to lock into the existing frame structure without tools.
03. Will the bottom cage get too hot?
Not if you use our Spacers. They create a 1-inch ventilation gap that prevents heat transfer from lights.
04. Can I mix different sizes?
Our stacking system is optimized for enclosures with the same footprint (e.g., 4x2x2 on top of 4x2x2).
