I am having trouble with the sparsness of the wheatgrass. I sprout until 1/4 tails appear and then sow in soil. I pretty much cover the entire flat but I would guess perhaps 1/3 of the sprouts result in grass. Also, the tips of the grass turn brown. I am growing indoors. Any help you can give will be greatly appreciate by both me and the cat.
Cheers
