@Arthur That is true that people have different starting points for counting. I basically call day 1 when it is fully above ground.
@damien50 that’s a good suggestion, I don’t think I need to be that precise though. I do change combination of different lights in each grow so it’s not always consistent.
@Mañ'O'Green ahhh, I think I get what you’re saying. so then if the seedling isn’t too hot or bombarded with too much infrared, it should be able to utilize as much light as it can regardless of it being over that amount?
I guess then in this case, it’s not too hot at 24C, and i may be wrong but I think COBs spectrums don’t include infrared, so adding the 3rd light couldn’t have a detrimental affect?
...or am I just high?
