  1. Hello,
    I wanted to know which qb's and how many I should get for a 50cm x 100cm x 50cm grow tent. Also, where could I get them in Germany, note that customs are a pain in the ass for everything right now.
    Thanks in advance!
     
  2. How many feet is 50x100cm?

  3. 30 cm is a ft I believe u could google it
     
  4. I’m sure I could but I’m watching a football game. So I was hoping the person asking for this info would do so. ‍♂️

  5. And 50cm = 1’. So the answer will more than likely be the hlg65s but again I’d wait for Tbone to respond.

  6. 5.5 sf x 40 watts per sf = 220 watts.

    A 4 pack of qb120’s with a Meanwell HLG-240H-c2100a driver will push 235 watts
     
  7. Wait am I missing something here? This is a 1’x2’ tent right 50cm =1 foot. How in gods green earth will he fit 4 120’s in a 1x2.? I’m interested to see how this works out lol.

  10. Math is my thing. I estimate and organize construction jobs for my home improvement company and deal with numbers all day long.
