  1. Ok so my first harvest is just around the corner and its going to get me some more funds to expand my grow. I have a 250 watt digital HPS with MH conversion. I want to have around 600 watts though, one question is

    Should i buy a 400 watt lumatek and use it with the 250 watt i have now or just buy a 600 watt lumatek and put the 250 in storage? I dont wanna go above 650 watts power usage cause it would be expensive.

    Now second i was wondering if this is a good tent? It is off ebay for 90 bucks! and is the perfect size for me.


    Next i would like to talk air flow, how much cfms of exhaust and intake would i need for the above tent and 600-650 watts of HPS?

    And are these fans good? 6 inch fan

    Last question:
    What is the best type of reflector for easy cooling? These are the choices.

    Im using ebay for the tent, and for the light, and im not sure about the fans yet but maybe

    thanks in advance if you help me [​IMG]
  2. with 2 250w setups you could keep the temps under control.

    I have that tent and a 600w light, if you have a glassed / air cooled reflector you can manage the heat.
