Farside, when do you decide that your seedlings are ready for more light. Is it a particular stage of growth? I’ve had some under about 18000lux since sprout and they’re just over 2 weeks. They have super tight node spacing, almost too tight. I’m thinking they’re ready for me to drop the light a it but am worried it will be too much for them and they’ll stay even tighter. I have a similar light setup - why i ask here (for veg, 640 diodes at 3500K in a 3’ x 3’, I have some 3000K to add in for flower)
I start my seedlings around 20,000 lux. They'll get that for about the first 10-14 days from breaking ground. Early veg I'll up it to 30,000 (about week 3). Veg I keep it around 40,000, and Bloom I'll go 50,000. Was going up to 70,000 in later Bloom but I'm noticing light stress at that level. I think I'm gonna leave it at 50,000 this next grow. Really I don't think I'm moving my light too much until the stretch. The first couple increment (20k,30k,40k) the plants are just gaining height and increasing the level at the tops on their own. My node spacing is very tight, but I like it that way. I don't have that tall of a tent so the stockier the better.
