K..... I hear y'all.... Ventilation... Got it figured.....
To keep things discrete I just bought a couple bilge fans...
3 of em..... 4"... I've got limited space to vent outside due to the concrete walls in the basement, But I have room to pop 2 more 4' holes.... Everything vents under my deck, and I made some activated carbon filters at work...

Each of these fans puts out 192cfm without a filter, so with im guessing 150cfm each with filters. Sound right?

Also I just ordered 2x 600w HPS for dirt cheap....

So thats two 600w HPS, one 400w HPS, three 150cfm Bilge fans going out, Sufficient air in. That's my flowering room. When these girls are done I'll upgrade hard.

Can it shock the shit out of them if I add more lights, or will it all be good? I'm growing my first batch of purple power, and I'd hate to waste em.......
