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.

You need to have some light above the seed or it won't know what to reach for. It does not have to be intense.

You need a light as soon as the seedling breaks the surface of the soil.

You need light before the seed breaks surface.:thumbsup:

I germinate mine at the end of my veg closet. No muss, no fuss.
Seeds can not see light or dark if they are under ground. Keep them moist and warm and make sure when you notice the first one poking thru, start them on the timer. Should start greening up in no time after tossing its shell.

Sorry Stinky...just saw your post in there.

Hey thanks all, I mean I always did just in case with a little floro 25 watter, but then after I read they didn't require light right away then why waste the time ya know?
:thumbsup:

I'm pretty sure that a sprout can see the light when it is 1/4 or 1/2 inch below the soil. That little bit of soil is not solid, and light does penetrate the surface. Also, when I close my eyes I can still tell a difference between light and dark. I'm fairly certain that plants don't have eyeballs, but just to be safe I try to get a little light over them at least within 2 days of planting. Helps keep em warm too. I imagine you would not really need to do so until you see the first sign of life.

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.

Hey stinky, anyone. How does gravity affect a seed sprouting and growing?

I read somewhere that 24 hrs of light encourages males, whaddya think?

I haven't seen an issue with m/f ratios. I think to get to the point where you would notice a difference, your sample size would have to be huge- like, a hundred plants at a time to see anything statistically significant.

I keep light on my seedlings 24 hrs and I have always had a greater than 50% female.

Thanks Dutch Pimp. So what have we learned?

imbibition
testa
ratticle
hypocotyl
cotyledon
abscision
dicots
etiolate
de-etiolation
skotomorphogenesis
phytochrome
photomorphogenesis

Should we be using these words in mixed company? Anyways, study up. Test nest Tuesday.
