  1. 1, Light 250/400 m, with bulbs. Will be getting one more 250/400 light set. Need advice on what to get next. Fans, filters, ect.......Thanks
     
  2. 2x 400w hps in that tent would be better than what most guys would do here...lol
    take a visit to you local grow shop

  3. (2) 6" fans, one for your air-cooled hoods and one for your filter. Use speed controllers to turn down your fans.
     
  4. See I have a enclose back porch, and I have 4x8x6'7" to play with. I just bought a Sun System 250/400 Digital built-in ballest. About to buy the same system Tuesday, and I was wonder is two 400 light systems powerful to handle the space I have. My book say 400 watts will handle a room 4x4 is that true. Thanks
     

  5. The weapon of choice is the ....600 watt HPS, the lumens at 98000, and the lumen to watt ratio is the best you can get from a HPS light, also the heat/watt ratio, 600w does 9 plants in 3 gallon pots in 1 sq. yard or meter, to 3 ft (1m) tall in 3 months, in potting mix, at 50/50 sat/indica mix.
    A 400w HPS does the same but kicks out 38000 lumen, so is 'slightly' less, with less heat to worry about, and finishing may take an extra week or so.

    Your 2 x 400w lights total an average of 76000 lumens 22000 lumens less than 1x 600w light, (or roughly 1 x 4" T5 rack of 6 tubes) but thats OK as you can get closer with the 400w than you can with the 600w.
    Your 2 400w's will easily handle 4x4, try 4x6 or just 2 sq yards and again bud an extra week

    peace
