So if this is the PAR mapping for my light at full 400w power in a 4x4 space. Do yall think think i ahould be running my light at 30% power in a 3x3 space hung at 14-15". I noticed the tips of the new growth looked a little brown today, couldnt get a clear pic, just wondering if Im overdoing it a little bit for seedlings. Right now im running it at 50% because that would have matched up with the light made for my tent, 240w.
As a general rule of thumb.. i go 200 for seedlings, 400 for veg, and 600 for flower. They don't require much light as seedlings. I use the photone par app for me iphone which helps a lot setting the right ppfd and DLI.
