I live in Brazil and it's almost year-round summer.
Always had problems with temperature when growing in a closet and HPS with the internal closet temperature during the summer time hitting almost 45 degrees celsius or more!
So this time I'm trying to grow in a Fully Working Fridge to keep the temperature down.
I brew beer as well so this fridge has a temperature controller and it keeps on 20-23 degrees celsius.
Using a 500w equivalent LED Panel.
For the air flow and exchange, the idea is to use a Carbon Scubber to constantly filter the internal air, a CO2 tank and an air de-humidifier.
The carbon filter will also reduce the odor and the fridge door is well sealed.
I guess it's like a big sealed grow room with air conditioner, but smaller.
