Noticed my leaves curling down, so I dimmed the light from 430-450 ppfd (28-30 dli) down to 375-395 ppfd (23-25 dli) was this the right move here? I just turned it up to 430-450 yesterday and
So my new plan is to keep the light at this level until they get their first real full leaves and then ramp it up to the mid 400s then when they start flowering ramp up to the high 500s. Seem about on track?
I have yet to go down the rabbit hole of DLI but I believe @Nicky has a thread that talks all about it. And I don’t grow autos but I think after 2 weeks they are not considered seedlings anymore.
Yea I’ve got the dli thing down I’m just not clear on the whole seedling/veg thing so I’m kinda guessing on the light levels because idk what stage I’m in. But the two weeks sounds like it would be right. I’m at day 10 so 4 more days until it’s really vegging I guess.
It’s a non exact science. Some say it when the first 2 full set of leafs (so the 3rd set of leafs) means your now in veg.
In reality just watch the stretch, more light keeps a plant shorter which isn’t a bad thing it helps grow the roots and not over stretch the young plant.
I always grow a really short and stocky plant for a couple nodes then start watching their Node spacing shooting for 1/2" after a couple nodes.
It’s an art.
Also I wouldn’t use that DLI advise from growers diarys
