I didn’t realize my light was in seedling spectrum

[Chieft666]

I didn’t realize my light was in seedling spectrum while I was trying to do a veg spectrum. So did I just did a month long seedling stage or does it also count as a veg? The smaller plant is do to too much heat. It bounced back though.

I run seedlings and veg under the same color temp. 6500K.

What are the plants and are they photo or autos. What is the light?

Most people look at the growth cycle like sprout to two weeks as seedlings. Then veg whatever length of days/time you want for photos. Then flip lights to flower when ever you want.

Autos hold you to their timeline.

Light spectrum does not hold the grow to any particular stage of growth in the plants life cycle. But bluer spectrum of light will keep the plants shorter with tighter node spacing. Redder light spectrum fosters vertical and vegetative type growth. You blend the two you have full spectrum.

I didnt kbow sedling spectrum existed...
Its all about light power.seedlings cant handle flower level lights. But spectrum.... yea blue and red to make it stretch or not.what spectrum is seedling?

It’s been vegging, the only difference is less spectrum of another color, I think less red. You won’t notice much if any difference. In my opinion the plant is vegging once the first set of leaves start to grow. As long as it’s receiving the proper DLI it’ll grow

Seedlings can handle more light than most folks give them credit for. By and large blue is seedling spectrum. Keeps stretch down, tight node spacing and good root development. I bought and still use from time to time HLG 100V2 @ 4000K for seedlings. When I bought them I was using HLG 260 Rspec lights and they have a lot of red so you had to be careful with them the first two weeks from sprout. Getting the ppfd up meant a lot of stretch. And they also induced a lot of stretch at flower flip. With the HLG 650R and 350R's I have in the tents now I can bring the seeds right out of the dirt and put the ppfd to them and not have stretch issues. And I'm finding out plants don't stretch much when I flip to flower like the more red spectrum lights do. Of course there is some strain/genetic issues at play. But with the big blue and red spectrum peaks they seem to work together well as a total package spectrum wise.

Soo whats the difference with seedling blue spectrum abd veg blue spectrum?

If you veg on the blue side your going to get smaller, tighter node plants. In the recent olden days. Many of use used white or blue side fluorescents for our seedlings. Then veg with MH because it was on the blue side then flower with a redder light. There were a lot of choices when it came to bulbs. Now we do it with leds with IMHO better control of spectrums and blending to get better full spectrum lights.
