I am purchasing a 400W HPS with a bat wing reflector coming with it. I can upgrade to a YieldmasterII air cooled for $58. Is the air cooled reflector needed? I ran a 150watt HPS air cooled one my first grow, but it didn't get too hot. Will I tell a difference without a aircooled hood? Soil grow, nothing else to cause heat but the light.
