Here are some pics of my cabinet and a design i made for you on " how to build one of your own with 2 chambers .you can build a box out of ALMOST ANYTHING , most important things are lighting , reflective surface inside , ventilation and airflow , and of course the space and or size that will suite your needs . If you check my grow journal and others here we almost all describe our boxes , cabinets and how they are made and what we used to make it . Good luck with things and i hope this helped a little !
If ya need anything else just ask . PEACE
