So as I wait to find time to get to the store all but 2 of my little seedlings are poking about the surface of the rooters. Some seem to be stretching over an inch tall and are just about to shed their seed shells and open up their seedling leaves. It might just be me, but they seem to be stretching upwards. Are they reaching for light?

I do not have them under a grow light yet because my veg room is still under construction. Hopefully it'll be done today with a DIY carbon filter and duct muffler.
