How much sun for Longan seedlings

[baccarat0809]

So, the first of my longan seedlings have sprouted and are up around 3 inches out of the soil.

I sprouted them on my patio / bird cage area but want to figure out if i need to leave them there and grow them out or if they should be put in the sun right away.

thanks

Gradually introduce more sun slowly to avoid burning
