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.

Leave humidity dome on seedlings?
Once the seedlings pop can I poke some more holes in the cups and leave them on for a while longer to maintain high humidity or will that put them at risk of rotting?

How much should i water in the beggining?
I'm growing Green Gelato Auto from RQS, this is the first day and it's hot outside (31ºC). I don't know if I'm watering too much or too little. I spray with water 10 times but it dries up after a few hours. Should I water it more?

Should I put the light on before sprouting or not?
I'm most likely going to be transferring my autos from paper towel into my medium, I've heard some people say have the light on before they sprout and some who say after it's sprout, which is the best thing to do?

- 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

When to pot the seedlings?
Hi! When is the best time to plant the jiffy pellets into pots? They sprouted yesterday, and are doing nicely in my propagator. Should I plant in pots now and keep them inside the propagator or leave them a little longer? Or just plant them up & put them inside the grow tent?

Seedling leaves turning white, no true leaves
Why have my seedling leaves turned white? One of them sprouted 3 days ago and it’s first true leaves haven’t sprouted yet? I am growing in coco and perlite and watering with water and rhizotonic? Is it because I haven’t let the soil dry out and I’m watering it everyday?

Pre-grow in 1L pots after germ? (Autofl.)
Not sure if i should put straight in the big pots after germ. I’m going to use Batmix, but as this can be overkill of nutritions on seedlings i was thinking either dig a hole in the pot and fill it with lightmix and the rest with batm., or put them in 1L pots of lightmix first?

Do you have a solution to stop the growth of stems?
Apparently this would be due to a lack of light and stress because of the too high temperature. I exposed them in a brighter place and I controlled the temperature to a maximum of 25/26°C. It doesn't seem to stop... How can I repair the damage? Is it too late? Thanks in advance.

PH problems (DWC)
I'm using 5% acetic acid (vinegar) to lower the pH but with 6 hours it's always back up to the original pH. A similar bucket with no aeration remains stable. Is it because I'm using a weak acid? Is there any way to buffer the solution to keep it in the desirable range?
