Moving seedlings outdoors earlier the better?

I was curious because I have never moved seedlings outdoors but I have a propogator 2 kit from nirvana seeds which for those of you who don't k ow what it is it's basically a little box that has lights in it and you add certain things to it specifically for soil just to get them out the ground. I read that the earlier you get your seedlings outdoors the better. If I were to put like a 2 day old seedling outdoors would I have to do a whole transition of getting it used to the sun or could I just put it right outside. Do temperatures matter should I not do it if it's too hot?

You should be good to go on the beginner leaves irregardless where you popped them. They should be born with a protective wax on those leaves. Personally not only do I like to get them out early I also like a little preveg to around a foot tall at least. But you will do extremely well this way also.

Found this article when I was thinking about global warming. Look ma, a sunblock for plants! Humans are amazing... (This is not necessary for you it's conversation only)

When mixed with water in the manner described and applied to growing crops, the above mixtures dry to form an insulating light and heat reflective film which is highly effective in accomplishing its intended purposes. Being virtually white, it reflects direct rays of the sun and obviates or minimizes sunburn of leaves, fruit, limbs and trunks of the crops. In areas of the San Joaquin Valley of California where the limbs of walnut trees are usually killed where exposed to direct sunlight, thus resulting in half limbs, the sprays of the present invention have made it possible to avoid such half limb destruction and may to permit Walnut trees to be grown with entirely sound limbs. The same has been true of peach trees. The sprays have also made it possible to avoid or minimize the sunburning of the trees and crops of plums, peaches, apricots, oranges, grapefruit, grapes, walnuts, and other fruits and nuts.
