The warmth is important. Just be sure that it is quite far away until the seed breaks surface, or risk drying out the soil.
I keep seedlings on 24h of light to keep temps stable.
stinkyattic Reviewed by stinkyattic on . lights on seeds I guess I always thought it didn't matter, but did it anyway in case., but I just read that it doesnt matter? Do any of you throw a light on after sowing your seeds? If it's done just for heat then that doesn't matter im just curious about the light part of it. Rating: 5
