Maybe I missed it but what were they growing in? Get yourself a 2 or 4 foot standard floures shop light and put it 2-3 inches over the sprouts. Raise the light as they grow always keeping them 2-3 inches away. Use a seed starting soil mix if you can find one, if not google how to make one. You live in a desert...is there sand in you mix? You can also use Rapid Rooter plugs or rockwool plug to start them. Just remember that rockwool has to be conditioned to maintain Ph. Good Luck.
