I have attempted growing onions from seeds, this time Spanish sweets and Granex hybrid. I have used the Jiffy peat discs where you rehydrate them. They have sprouted and are now 3 inches tall but the stems seem to have no real root and they just lay over and tend to die off. I don't believe I am overwatering them. I have thinned them out and the germination ratio seemed to be great with 65 out of 72 sprouting. I have them in my kitchen on an island under a sky light. This is my second round of attempting these. I live in Las Vegas, Nevada if that matters. What can I do to keep my seedlings from dying off, again?
