Thanks yeaster! It's a full addition I built a few months ago. A lot of work, time and money but it's fully tricked out. I have a journal of the build somewhere here.
Some of my fav features.
Flood tables are just for runoff but also have drains to the outdoors
Veg / water storage room is fully waterproof. With a pitched rubber floor with a drain.
Water area has a 50g resivour, blue lab guardian for Ppm and ph, water stones, drains and fill valve.
Co2 plumbed above the plants
Water is semi auto. Pumps and gravity lines to each table.
Built in drying cabinet with areas for different stages of drying.
Big ass leather chair to watch the girls grow and even a Keurig coffee pot.
Below is a photo of last grows start.
I suffer from severe OCD!! lol
