Wrong section man Ask grow related questions in the Marijuana Cultivation section but I'll help ya out. Intake isn't necessary because of passive intake(negative air pressure). If the 4" is strong enough to pull the hot air from the tent created from the 600w then you won't need another fan. Setup everything except for the plant. Record the temperature and humidity and you'll know if it'll work
