    For a 600w HPS (air cooled hood)?

    The 4x4x6.5 grow area will be cooled independently.

    many thanks

    10,000 CFM is ideal..... or really stupid one of the two lol

    150-250 would be fine, just put a small circulating fan inside to keep the plants moving a little to give you a strong stem
