It's nice dude, I got my airflow fan, can fan for carbon filter, besides the can fan blowing out, it's a passive airflow I got going on. Temps stay cool down there in the basement so as long as I'm not using more than 400w I won't have any problems. I could run six if I had the right hood for deeper penetration. Otherwise it might be too much light, which is possible. Only thing I'm worried about is bugs. Which it's almost time for an over haul in cleaning and re- set everything up. I found some spider webs going from the concrete wall to the outside of the wall of the tent. Blah, cleanup sucks, but has to be done. It was a good investment. Saved me the time and hassle of building a grow box myself. With the secret Jardin tents, you can pretty much find any tent you are looking for. I will be looking for one that is about 3 times the width, to finish off the wall. Just no need yet with just the 2 hps lights and stupid fluros I have. @CharmCity915
