Ok, i got a 6x4x8' grow room. I want to use half for veg and half flower, im gonna seperate the 2 rooms with black and white plastic and just mylar the black side.I got 3 different kinds of bagseed and waiting for my white russian to come in.So do you think i will need a filter in the veg room? Only plan on vegg for month. Or should i put 2 filters in the flower room?Im gonna try to get away with 6-7 plants under 400watt high pressure sodium with some cfls.Anyone grow white russian?How bad was smell during vegg?What did you do?I also have ona gel.
