Hey guys, I'm new to the forum and have been reading tutorials ect. and I'm thinking about growing. I'm planning on growing in a small (but not too small)"hidden room" on between my attic room and the roof of the building. I'm considering buying a 400W HPS bulb for 4 or so plants (is this a good number of plants?) And i'm wondering if a single oscillating fan (or some other fan?) will provide enough ventilation and also, since the attic is poorly ventilated, will the plants have enough CO2?
