Hello all! One of my baby Gorilla Glue’s opened this morning and I’ve got her all set up now. I need to dim my SE3000 down a lot and am wondering what PAR reading would be good for a new seedling? What’s the max? I have a Photobio Phantom PAR meter. Thanks much!
For a seedling I’m sure it’s around 200-500 ppfd, you can slowly ramp it up. This is what I have saved for myself.
Seedlings: 200-400 ppfd Vegetation: 400-600 ppfd Flower: 600-900 ppfd
Those are way off my dude.you wana be more at like 1000ppfd with seedlings and clones.they love the extra light and helps them grow big and fast
