my cp project is starting to get off the ground i have a 20 foot by 20 foot growing area (basement 6.5 foot ceiling) I'm making into a green house growing chamber for cp's i plan to grow any an all i can get my hands on. I'm adding 2 large ultrasonic humidifiers, an exhaust vent with fan, 8 pools as mini bog's and several shelfs for more growing space i will post pics at various points in construction. I'm very excited anyhow before this post gets to large here is my main questions:
*what wattage, Kelvin, mounting distance/position, high pressure sodium bulb would i need to * *
*cover the entire room? Suggested ballast unit to accompany it? Other light bulb types that should accompany HPS bulbs for proper light spectrum?
*how powerful a exhaust fan would be needed? Air intake/cross ventilation fan needed?
*Any special priming/painting required to prep room for high humidity/heat? ( basment has concrete floors wood sealing beam's sheet rock walls painted with interior paint ) humidity level for broad spectrum of plant's?
*can any one offer suggestions on a project like this possibly things i should consider, other items i might need. any input is much welcome/needed.
i may edit with more questions later as they pop up.
thanks for reading/commenting
