If it's just for one seed. 23 watt 6500k bulb will do. Just keep it 3 to 4 inches above the seed when it pops out. If you don't have a 6500k bulb 5000k will do. Best of luck with your grow.

That depends on how many seedlings and size of the space.

First true leave not visible , not growing , why ?
California Snow Auto popped out very well but looks like it does not have first true leaves and looks like they are not growing. Other seedling looks great at this moment. Do you know what could cause the issue like that ? Is this only genetics or it can be wrong environment ?

From germination to big pot?
I transferred my auto seedlings in their plugs to a small, transitional pot. Is it true autos can and should go straight from germination to the big pot without a stepping stone?

Seeds in 12/12
Does keeping seedlings just the first week under a 12/12 light cycle can hurt them? I have some seeds that are not sprouting after 7 days, maybe it's because the outside temperature is too low so I decided to keep them in my growbox with my other flowering plants until they start

please look at my seed 3 days after germination and tell me if she is a goner
my germination pot fell while being moved. one seed got out but it wasn't rooted yet, I put it back in. do you think she will be okey or do I germinate another one? I damaged the tip of the root when putting the root in the hole.

- I have a greenhouse ceiling that covers 50% of the terrace - should I grow the plants always under this ceiling, or if it is beneficial to expose the plants to direct sunlight? - If so, how old the plant has to be to expose it to the sunlight? I don't want to burn my seedling

Light Burn? Mars Hydro TS3000 at 30% Power, 26 inches away per manual. I have since raised back to 30 inches.
Is this light burn? I noticed some slight yellowing/crispy looking leaf at day 11. Light is about 30% Power, about 30 inches away. I previously had it about 26 inches and raised when I noticed this issue about 24 hrs ago. Pics are updated. Temps: 70-75 RH: 50-60 Soil Runoff: 6.5
