Why diff? Phadubious asked a question about something not posted. I know you have been reading the thread. Pisses me off having done all the work, people can’t even read the f’king thread, for things already posted.
This is quick and dirty, cuz my test gear is stored, but should be close enuff.
@ ~125w, directly under single 96:
25” ~ 300 ppfd
22” ~ 400 ppfd
18” ~ 500 ppfd
16” ~ 600 ppfd
If you look at the single 96 maps, you can get very close to this by looking at the 120w tables at diff hts. Let me know if you want me to walk you thru it, may save you time in future.
For veg, 300-600ppfd is recommended.
