I let the root grow a bit too long say 3 inches give or take. Anyhow i sowed it 2 days ago and now it has sprouted but the casing is still attached to the sproutling[?]. I have germinated a few times and it has sprouted a few times but always has the sprout casing stuck to it and it always stretches. It has never happned to me before. To prevent my plants from stretching should i put it under light? I mean i dont see why i should because the leaves dont even show because of the seed case still stuck to it. I pulled off the casing once but it was quite unwise. what should I do?
