I am new to this site. My husband and I have recently tried to grow our own. We made a PC grow box with two lights (I will have to ask him to be sure of what kind of lights). We purchased some seeds and put one in a pot. It started to sprout, but the seed seems to still be on the top. It has now been about 4 days like this. The plant is increasing in height, but there are no leaves. Also the plant has a rather brown hue. The brown color has got us a little concerned. I know this can be rather common, but should I attempt to remove the seed with some water or would it be better to just leave it be and let nature do its thing?
