I think that's it for me maybe...little light they can see with their 0 eyeballs...I swear they can feel that warmth though and follow it....I'm sure Shed will bite that in the ass and say it's inanimate, it doesn't have feelings. Lol right, I'm sure, but I like to believe in MAGICSorry, I'm not them but I saw this. It makes zero difference. It will come up regardless. I keep mine in the light cuz I believe the little seedling can "see" the light it's striving for if you leave it on. The dirt is brighter above it than below it and I believe the seedling knows it. But it will come up either way. If either of these much more experienced guys says anything different I'll be shocked. But I'll learn something.
