Ran some seedlings at around 900ppfd from germination, worked out well Bugbee was right weed sites wrong that 300ppfd is too low light.
Averaging the same outdoors zero issue either.
Not the best photos presently under a Mars hydro fc-3000 Evo in an 80x80cm tent. Whole tent is Mars hydro with iconnect, hub, fan and inline/filter.
My photone app is pretty consistent with the advertised figures for 12 and 16", seems to read led better than other lights as first light it's matched the ppfd maps.
Bugbee was right, seedlings can take much more light than we thought, the same as flowering meaning one ppfd Will do start to finish.
Disagree all you want I was as shocked as you, this is my next run just trying to find tune things a little more, I might find they need more or less to hit optimum but going down to 300ppfd for seedlings just produces weak slow things whilst after four days at 900ppfd I'm growing monsters already.
Zero signs of heat or light stress how is that possible at 900ppfd unless one side was seriously wrong here.
Anyone else using flowering figures for seedlings and not torching them as the info suggests?
