Quick Question For Growers

Discussion in 'First Time Marijuana Growers' started by NaiveTerror, Jul 24, 2014.

  1. when growing outside, what is it compared to indoor lighting? how would i know if its getting enough light outside? how would u compare it to a grow light?

     
  2. 10,000 lumens per Sq ft

    1kw in a 4x4 is the same as full sunlight, 165,000 lumens/16 sq ft.
     
  3. 1,500 watts per square meter.
     
  4. So if I had a 600 watt how would I mimic sunlight

  5. What are the demensions of Your growing space?
    I cannot help You on this but it is useful for someone who can.
    Usually 600w can get You a nice grow though. :)
     
  6.  
     
    Metal Halide for veg
     
    High pressure sodium for flowering.
     
  7. I was meaning lumen wise

    It's shit compared to indoor lights but it's free. At least here in the UK anyway. Bud doesn't form as good on my outdoor plants anywhere near as good as my indoor ones. Most days the sun light is largely filtered out by the clouds. So it very much depends on where you live, and of course time of the year is a massive factor
     
  10. How is marijuana in the UK? Potent? Just a thought.

    A 600w HPS lighting up 1 metre square will provide around 90,000 LUX and here is the wiki list of sunlight intensity. It doesn't mention how close to the equator or time of year so very much rough estimates really

    September and October sun is like a candle in the sky in the UK. Just when bud is fattening up it goes cold and dim. Thank the gods for automatic flowering plants

    Potency is the same wherever you grow. It's all in the genetics providing you have a healthy plant. Obviously a sick plant will have issues, but as long as it healthy potency isn't effected. Yield is massively effected though. My indoor plants always yield better 
     
  13. Southern California gets 120k lux about 300 days a year. Long live the cali sun.
     
  14. Just checked out Your grow. Looks awesome! I've been into scrogs lately. Can You really tell the difference of the yield?

    Thanks man, yeah huge difference 
     
  16. Your welcome. :)
