In the big tent there is close to 2k watts true draw less parafact works is like 2300ish at 12 in height the light meter I use shows like 1500 to 2000 over 95% of the room but it’s just a cheap light meter like 8x7 x 7 space wrapped in reflective Mylar but there is 6 different brands of lights they start under like 500ish true watts at 18 i I don’t worry too much about all that just as long as I get results if the strain is good genetics I get the higher end of the yield charts and size charts the 3 I’m running on here make it 18 auto strains since March running mostly this setup
